The concept of portable, one and two man, hole digging equipment has been successfully utilized for manyyears as a practical solution to many types of hole digging job requirements. The basic concept is provenand well accepted within the associated marketplaces. Use of a Hole Digger requires strenuous workactivity. This type of work activity can be considered to be greater in magnitude than that experiencedwith the use of many other types of both light construction and lawn and garden related equipment. This

type of work activity should only be attempted by operators of adequate physical size and stature, mentalawareness and physical strength and condition. The body parts most noticeably affected during the holedigging process are the arms, hands, wrists, shoulders, lower back and legs. The process can also produceexcessive stress/strain directly to the back muscles, spinal vertebrae and many other body parts. Back andwrist related pain can be side effects of utilizing a Hole Digger. A potential operator with a chronic backrelated problem or a history of back and/or other medically related problems should not attempt to utilizethe Hole Digger. Use of the Hole Digger may only aggravate this and any other medically related problem.Because of the diverse type of prevailing job applications, job site conditions, operator experience levelsand operator physical characteristics, no warranty, guarantee, representation and/or liability is made by themanufacturer as to the absolute correctness or sufficiency of any operational procedure, operationalposition and/or technique. There is no absolute guarantee that an operator of any given experience level,physical size and/or physical condition will be immune to the possibility of and/or probable physical sideeffects of the normal use of the Hole Digger. Each potential operator must be made aware of and assumethe operational and physical liability described and/or associated with the use of the Hole Digger. Improper

use of the Hole Digger can result in property damage and/or personal injury, including death. Eachpotential operator not willing to assume the operational and physical liability described and/or associatedwith the use of the Hole Digger, should not operate it. Proper levels of operator experience, skill andcommon sense are essential for maximizing the safe and efficient operation of the Hole Digger

Safety Precautions

THE FOLLOWING SAFETY PRECAUTIONSPROVIDE SOME COMMON SENSE GUIDES TO

PROMOTE SAFETY AND EFFICIENCY WITH THE300 SERIES HOLE DIGGERS. NO WARRANTY,GUARANTEE OR REPRESENTATION IS MADE BYTHE MANUFACTURER AS TO THE ABSOLUTECORRECTNESS OR SUFFICIENCY OF ANYINFORMATION OR STATEMENT. THESE SAFETYPRECAUTIONS ARE INTENDED TO DEALPRINCIPALLY WITH COMMON PRACTICES ANDCONDITIONS ENCOUNTERED IN THE USE OF THEHOLE DIGGER AND ARE NOT INTENDED TO BEALL INCLUSIVE. PROPER LEVELS OF OPERATOREXPERIENCE, SKILL AND COMMON SENSE AREESSENTIAL FOR SAFE AND EFFICIENTOPERATION.

THE ENGINE EXHAUST FROM THIS PRODUCTCONTAINS CHEMICALS KNOWN TO THE STATE OFCALIFORNIA TO CAUSE CANCER, BIRTH DEFECTSOR OTHER REPRODUCTIVE HARM. THISSTATEMENT IS MADE IN COMPLIANCE TOCALIFORNIA PROPOSITION 65.

INCORRECT USE OF THE HOLE DIGGER CANRESULT IN PROPERTY DAMAGE, PERSONALINJURY OR EVEN DEATH. TO REDUCE THISPOSSIBILITY, GIVE COMPLETE AND UNDIVIDEDATTENTION TO THE JOB AT HAND AND FOLLOWTHESE SAFETY PRECAUTIONS:

PREPARATION.

1) The 300 Series Hole Diggers are a specialized typeof powered equipment, designed for a specific jobfunction and requires adequate and thoroughinstruction BEFORE it is operated. The size, power,complexity and operating characteristics of this type of

powered equipment would dictate that each operatormust receive adequate, professional instructionregarding the proper operation of this Hole Diggerbefore being allowed to utilize it. BEFORE attempting toutilize this Hole Digger, read this Operator's Manual, theapplicable Safety and Operational Information VideoTape and the material supplied by the enginemanufacturer to familiarize each operator with itscorrect operating procedures. Avoid the urge not to takethe necessary time to read this Operator's Manual

before operating the Hole Digger. DO NOT OPERATETHE HOLE DIGGER UNTIL EACH OPERATORCOMPLETELY COMPREHENDS THE CONTENTS OFTHIS MANUAL, THE APPLICABLE SAFETY ANDOPERATIONAL INFORMATION VIDEO TAPE,APPLICABLE SUPPLEMENTAL INFORMATION ANDTHE INFORMATION SUPPLIED BY THE ENGINEMANUFACTURER.

2) Develop a comprehensive program for the safeoperation of the Hole Digger by its owner(s) and/oroperator(s). Such a program will include, but is notlimited to: instructional requirements for operation,applicable OSHA requirements, local laws andregulations, job site safety and a Hole Diggermaintenance program. Constantly examine andupgrade this program to guarantee owner(s) and/oroperator(s) safety. Each operator must be fullyinstructed regarding the specifics of this safetyprogram.

3) Determine that the Hole Digger is in its original,

factory configuration and has not been modified in anymanner. Many modifications can result in potentiallydangerous configurations that can lead to propertydamage and/or personal injury. If there are anyquestions about possible modifications made to theHole Digger, contact the Customer Service Departmentfor specific information BEFORE utilization. There is nocharge for this service.

4) Minors should never be allowed to operate the HoleDigger. Bystanders, especially children and animals,should not be allowed in the area where the HoleDigger is in use. The hole digging process can result inflying particles being emitted at high velocity and

striking the operator and/or onlookers. This can lead tothe possibility of property damage and/or personalinjury. Keep all body parts, loose clothing, foreignobjects and onlookers clear of the rotating auger and/orauger extensions.

5) Operators must be in proper physical condition,mental health and not under the influence of anysubstance (drugs, alcohol, etc.) which might impairvision, dexterity or judgment. Working with the HoleDigger is strenuous. If you have any condition that mightbe aggravated by strenuous work, check with yourdoctor BEFORE operating the Hole Digger. Guardagainst the possibility of back related injuries. Always lift

the Hole Digger with leg muscles and not with the back.Operators must be of adequate height so that for anygiven operating configuration, the operator handle(s)remain below their shoulder sockets. Do not operate theHole Digger if this condition is not satisfied. The 300Series Hole Diggers require that both operators be ofsimilar height, weight and strength to maximize diggingefficiency and minimize the possibility of personalinjury. Both operators share the burden associated withthe hole digging process.


11/69


12/69


2) The 300 Series Hole Diggers are not sealed orinsulated. Do not operate any Hole Digger in anexplosive atmosphere or near combustible materials.Refer to current OSHA rules and regulations.

3) Gasoline is an extremely flammable fuel. Useextreme caution when handling gasoline or mixingfuel. Always utilize UL, CSA OR CE approvedcontainers for the storage and transportation of fuel.Do not smoke or bring fire or flame near the fuel.Always shut off the engine and allow it to cool beforerefueling. Never remove the fuel tank filler cap whilethe engine is running. Never operate an enginewithout a fuel tank filler cap. Select bare ground forfueling and move at least 10 feet from the fueling spotbefore starting the engine. Wipe off any spilled fuelbefore starting the engine and check for leakage. If afuel or oil leak is found, do not start or run the engineuntil the leak is fixed and the spillage has been wipedaway. Take care not to get fuel or oil on your clothing.If this happens, change your clothing immediately.Before operating the Hole Digger refer to the

Specifications section of this manual for moredetailed information regarding fuel and lubricationrequirements.

4) The 300 Series Hole Diggers are designed for use bytwo operators. Use of the Hole Digger by one or morethan two operators can lead to confusion and loss ofcontrol, resulting in property damage and/or personalinjury. Never operate the Hole Digger with an impropernumber of operators. Such a configuration can result inproperty damage and/or personal injury. If it is felt thatmore than two persons are required to furnishadditional "down pressure" to the auger, STOP andcontact the Customer Service Department for specific

operational and service/maintenance information.There is no charge for this service.

5) Do not operate the Hole Digger with onlookers closeby. Caution all onlookers to stand clear. The holedigging process can result in flying particles beingemitted at high velocity and striking the operator and/oronlookers. This can lead to the possibility of propertydamage and/or personal injury. Wear proper safetyeyewear. Keep all body par ts, loose clothing and foreignobjects clear of the rotating auger.

6) Do not utilize a shovel and/or foreign object toremove loose soil from around the hole area while the

Hole Digger is in use. Such a practice can result in theshovel and/or foreign object to become entrapped bythe rotating auger, leading to property damage and/orpersonal injury.

7) Start the engine according to the instructions asoutlined in this manual to minimize the possibility ofunexpected auger rotation. Unexpected auger rotationcan result in the loss of machine control and thepossibility of property damage and/or personal injury.

8) Start and operate the Hole Digger only in a wellventilated area. Carbon Monoxide fumes given off by anengine are poisonous. Breathing these fumes canresult in property damage and/or personal injury.Operate the Hole Digger only when/where visibility andlight are adequate for the job at hand. Work carefully.Always hold the operator handles firmly with bothhands. Wrap your fingers around the handles, keepingthem cradled between your thumbs and fingers. Alwaysdetermine the operator handles are in good conditionand free of moisture, pitch, oil or grease. Wear glovesto improve your grip. Never leave the Hole Diggerrunning unattended.

9) Stop the engine between each hole. Allowing theengine to remain operating between each holesubstantially increases the potential for propertydamage and/or personal injury. Special care must beexercised on slippery conditions and on difficult,uneven surfaces. Watch for cracks, high spots andother surface irregularities. Keep proper footing andbalance at all times. The normal use of this machine ison level surfaces. Other terrains can be dangerous andshould be avoided. Only properly trained operatorsshould attempt these techniques.

10) The 300 Series Hole Diggers are designed to bestarted by both operators in the following manner: theCrew Chief regulates engine speed (RPM) with theengine throttle control while the Crew Member startsthe engine by use of the recoil starter. The Crew Chiefis responsible for the necessary verbal commands.Never operate a 300 Series Hole Digger if it requiresone of the operators to operate the engine throttlecontrol, carburetor choke system and the engine recoilstarter (or any combination) at the same time. This is

not a factory designed operating configuration for theHole Digger. Such configuration(s) will result in loss ofmachine control, property damage and personal injury.Contact the Customer Service Department forinformation relative to restoring the Hole Digger to itsoriginal configuration BEFORE further utilization. Thereis no charge for this service.

11) Contact with a hot, engine muffler can causeproperty damage and/or personal injury. Remain clearof a hot engine muffler. Do not over speed the engineby altering the governor setting or by disconnecting theengine governor. Serious damage to the engine and/orpersonal injury can result.

12) The 300 Series Hole Digger are powered bygasoline engines which produce Carbon Monoxidefumes during the combustion process. CarbonMonoxide fumes are poisonous. Breathing CarbonMonoxide fumes while operating the Hole Digger canresult in property damage and/or personal injury. thenormal operation of the Hole Digger is outdoors wherethe potential effects of Carbon Monoxide to theoperators are minimized. If the Hole Digger is operatedin a closed area (indoors or outdoors), determine if


13/69


supplemental ventilation is required to minimize thepotential effects of Carbon Monoxide to the operators.Follow all current OSHA regulations pertaining toventilation.

13) Because this Hole Digger is classified as a lowcost, hand held, low horsepower, portable typemachine, it is limited in the number of practical and/orsuitable job applications. A particular job site, actualsurface conditions, job specifications and operatorskill/common sense may dictate that a different type ofmachine (with characteristics of higher purchase cost,being mounted to a carrier vehicle, with greaterhorsepower and less mobility), method and/or processbe utilized to properly complete the job with the degreeof efficiency and safety required. Contact the CustomerService Department for specific information regardingsuitable job applications, job site surface conditions andoperator experience/skill/common senserecommendations for the Hole Digger BEFOREutilization. There is no charge for this service.

MAINTENANCE, REPAIR AND STORAGE.

1) Use only genuine, approved replacement parts andaccessories for maintenance and repair. Use of partsand accessories manufactured by others can result inproperty damage and/or personal injury.

2) Follow the Service instructions as outlined in theappropriate section of this manual.

3) Always stop the engine and disconnect the sparkplug wire BEFORE checking or working on the HoleDigger.

4) Always properly maintain the Hole Digger.Frequently check all fasteners and individual parts. Builtin safety features are effective only if they aremaintained in good working condition. Replace anyquestionable part or assembly with a genuine, factoryapproved, replacement part. Do not forsake propermaintenance for the price of a few replacement parts.Proper maintenance does not cost...it actually paysdividends. Do not attempt any maintenance repair worknot described in this manual. Have such workperformed at your dealer's service facility.

5) Determine the engine throttle control and throttlecable assemblies are not damaged and allow for

complete freedom of movement. This is necessary toallow them to perform their intended job functions. Donot operate the Hole Digger with a damaged enginethrottle control and/or throttle cable assembly.

6) A worn or damaged engine muffler is a fire hazardand may cause loss of hearing. Check to see that themuffler is in good condition. If the muffler is equippedwith a spark arresting device, determine that it is inproper working condition at regular service intervals.Replace the spark arresting device with an approved

replacement if there is any question of its integrity. It isthe responsibility of the owner(s) and/or operator(s) toprovide for and properly maintain a USDA approved,spark arresting muffler in an operating area specifiedby law. Check with appropriate governing agencies formore specific information. The Hole Digger must not beoperated if the muffler is faulty or has been removed.Contact with a hot engine muffler can cause propertydamage and/or personal injury.

7) Maintain all safety and operation decals in propercondition. If any decal becomes damaged and/orunreadable, replace with a genuine, factory approved,replacement part only.

8) The Hole Digger may utilize self locking typehexagon head nuts to minimize the effects of vibration.Replace all self locking hardware with genuine, factoryapproved, replacement parts only.

9) Consult the material supplied by the enginemanufacturer for specific information relative to properoperational, lubrication and storage requirements.

10) Replace the auger teeth and screw bit when signsof excessive wear are seen. When such componentsare not replaced at proper intervals, excessive wear willoccur at the boring head and auger flighting. The endresult is an inverted cone configuration for the augerwhich usually requires complete replacement. FIGURE1. Digging with augers that are past their useful servicelife or that have not been properly maintained can resultin substandard productivity, excessive propertydamage and/or personal injury. Auger service life canbe greatly extended with a consistent augermaintenance program.

11) At the conclusion of the useful service life of theHole Digger, drain and properly dispose of all fluids perlocal requirements. Disassemble engine andtransmission components. Wear appropriate safetyapparel during the disassembly process. Recyclealuminum, steel and nonmetallic components properlyper local requirements.

FOR OPERATIONAL SAFETY ANDPRODUCTIVITY CONSIDERATIONS, IT ISEXTREMELY IMPORTANT THAT INNER WIRESLACK BE COMPLETELY REMOVED FROM

THE THROTTLE CONTROL SYSTEM. INNERWIRE SLACK CAN REDUCE OVERALLOPERATOR CONTROL, RESULTING INPROPERTY DAMAGE AND/OR PERSONALINJURY.

10) Rotate the throttle control counterclockwise (themaximum speed position) to determine that the inner

wire pulls the throttle lever of the carburetor forward,against its stop. Improper adjustment will not allow theengine to operate at its maximum, no load, governedspeed and affect the overall digging performance of theHole Digger. Adjust the swivel assembly and throttlecable attach bracket as necessary to allow for completefreedom of movement.

Check for possible throttle cable inner wire binding andmovement restrictions caused by the clip and clamp.Rework and adjust as necessary to allow for completefreedom of movement.

11) Using the cut off pliers, cut the remaining inner wire

behind the swivel assembly, leaving approximately oneinch (25.4 mm) of excess wire.

12) Check all fasteners for security. Consult a fastenertorque chart for proper torque value if any fastener isfound to require retorquing.

NOTES TO THE THROTTLE CABLEINSTALLATION.

Application: 330H, 343H and 357H Hole Diggerspowered by the Honda GXV160 engine.

1) The Honda GXV160 engine incorporates a

multipurposed carburetor/throttle arm design thatallows it to be utilized with both Bowden (push) andbraided wire (pull) type configurations. For simplicity,productivity and service reasons, the Hole Diggerincorporates a braided wire (pull) type configuration. AMagura twist grip throttle control is utilized as theengine speed control device. The Magura throttlecontrol has proven to be a rugged, dependable devicethat delivers exceptional service while requiring onlyminimal service.

2) The GXV160 engine utilizes one or two springloaded screws as stops for the carburetor throttle arm.

a) If equipped, the shorter (inner) screw is nonfunctional for this application.

b) The longer (outer) screw is factory set to prevent theengine from operating in an overspeed configuration.As set at the factory, the GXV160 engine will operate atapproximately 3800/3900 RPM no load. In a no loadconfiguration the engine is operating at maximumgoverned speed without an earth auger attached to thetransmission driveshaft.

Before Starting the Engine

FILLING THE ENGINE CRANKCASE WITH OIL.

Application: 330H, 343H and 357H HoleDiggers powered by the Honda GXV160engine.

Tools Required:

1 each, small, adjustable wrench (if needed)1 each, small, clean funnel with a flexible extension

spout

Filling the engine crankcase with oil will require a levelworking platform of sufficient size and appropriateheight. As an alternative, the transmission driveshaftcan be securely in a suitable bench vise.

1) Wipe any dust or dirt from the crankcasedipstick/filler plug area. Remove the dipstick/filler plug.

2) Using the funnel, add oil to the engine crankcase. Forproper classifications and/or amount, consult the

material supplied by the engine manufacturer forspecific information.

3) Relace the dipstick/filler plug and tighten. Wipe offany excess spilled oil. Properly dispose of the spilledoil.

4) Consult the material supplied by the enginemanufacturer for other service related informationincluding oil change interval.

DO NOT OPERATE THE HOLE DIGGERUNLESS PROPER OIL LEVEL IS MAINTAINED.IMPROPER OIL LEVEL CAN RESULT INPROPERTY DAMAGE AND/OR PERSONALINJURY. CONSULT THE MATERIAL SUPPLIEDBY THE SPECIFIC ENGINE MANUFACTURERFOR INFORMATION RELATIVE TO PROPERMAINTENANCE PROCEDURES.

FILLING THE HOLE DIGGER TRANSMISSIONWITH OIL.

Application: All 300 Series models.

Tools Required:1 each, small adjustable wrench.1 each, small, clean funnel with a flexible

extension spout.

Filling the transmission with oil will require a levelworking platform of sufficient size and appropriateheight. An alternative, the transmission driveshaft canbe securely mounted in a suitable bench vise.

1) Wipe any dust or dirt from the transmission oilfiller/level plug area. The oil filler/level plug is located onthe side of the transmission. Remove the plug with theadjustable wrench.

2) Using the funnel, pour 1 US quart (0.94 liter) ofGeneral Equipment Company transmission and Engine

Oil, PN 999-11, ora high grade, SAE 30 Detergent or10W30 motor oil into the transmission though the oilfiller/level plug opening. Use only an oil marked with anengine service classification SF, SG, or SH/CD. As ageneral rule, the transmission is usually filled with thesame oil type and weight that is utilized in theapplicable 4-Cycle engine crankcase. FIGURE 9.

3) The transmission oil level is to be maintained at thebottom of the oil filler/level plug hole. Allow any excessoil to drain out of the transmission. This proceduredetermines the correct oil level for the transmission.Correct oil level is important to insure proper centrifugalclutch operation. Maintaining the oil level too high will

cause excessive centrifugal clutch slippage and resultin high oil temperature. Excessive slippage and high oiltemperature will significantly reduce the service life ofthe clutch assembly and affect the overall performanceof the Hole Digger.

4) Inspect the oil filler/level plug gasket for propersecurity. If necessary, replace the gasket with a factoryapproved replacement part only. Reinstall the oilfiller/level plug. Tighten securely with the adjustablewrench. Wipe off any excess oil spilled on thetransmission. Properly dispose of the spilled oil.

INFORMATION RELATIVE TO COMPOSITEMATERIAL OPERATOR HANDLES.


The Hole Digger may utilize operator handlesconstructed of a specially designed, S-Typecomposite material intended to reducemachine weight and help absorb the shockloads transmitted to the operators during thedigging process. This material has shown tobe very durable and will offer a very


22/69


acceptable service life. However, it will nottolerate the same amount of external damageas steel tubing without some sacrifice of itsappearance and/or physical strengthproperties. Protect the handles from externalsources of damage. Do not allow the handlesto come in contact with augers, shovels, orother sharp and abrasive objects during

transit. Do not stack or throw similar objectson the handles during storage. Keep thehandles clean and free of dirt, moisture,grease, oil and other, foreign materialaccumulations. Exercising properpreventative maintenance for the handles willresult in an extended service life.

USE OF THE COMPOSITE MATERIALOPERATOR HANDLES DOES NOT ELIMINATETHE POTENTIAL FOR PROPERTY DAMAGE

AND/OR PERSONAL INJURY IF CONTACTWITH A BURIED ELECTRICAL CABLE ISMADE. SEE: DETERMINATION OF POTENTIALSUBSURFACE HAZARDS IN THE PROPOSEDDIGGING CONDITION(S) ELSEWHERE IN THISOPERATOR MANUAL.

1) Operator handles are constructed from a compositematerial with a demonstrated high dielectric constant.This insulating characteristic alone does not guaranteethat contact with a buried electrical cable will not allowenergy to be transmitted directly to the operators. Otherfactors reducing the insulating characteristics of theoperator handle configuration include, but are not

limited to:

a) Throttle cable. The throttle cable connects directly tothe engine according to the design offered by thespecific engine manufacture. The throttle cable ismanufactured from conductive type materials forstrength and durability purposes. This allows energy toflow from the auger through the engine and directly tothe Magura throttle control.

b) Throttle control. The Magura throttle control isfabricated from reinforced plastic. There is noguarantee the design configuration will eliminateenergy being transmitted from the throttle cable,

through the throttle control and directly to the operator.

c) External condition of the operator handles.Accumulation of moisture, dirt, pitch and other foreignsubstance can provide a conductive pathway for energyto be transmitted from the exterior of the operatorhandle and directly to the operator. It is recommendedthat operator handles be maintained in a clean, drycondition and free of all foreign materials.

2) The composite material is formulated by itsmanufacturer with an inhibitor to reduce (but noteliminate) the long term effects of ultra violet radiationfrom the sun. However, it is still recommended thecomposite material operator handles be protected fromultra violet radiation whenever possible to extend theirservice life.

3) Composite material operator handles are coatedwith a polyurethane finish to help protect from externaldamage and abuse. With normal usage andenvironmental effects, small strands of fiber canprotrude from the exterior surface. When performingpreventative maintenance on the Hole Digger, theprotective covering can be restored by lightly sandingthe handle surface with 240 grit sandpaper and thenapplying two, thin coats of polyurethane.

Wear all appropriate safety apparel and

equipment when utilizing the sandpaper andclear polyurethane spray. Follow allappropriate safety precautions for the use ofthese materials.

4) A composite material operator handle with a cut orabrasion greater than 0.125 inch (3.2 mm) deep andone inch (25 mm) long must be removed from serviceand replaced with a factory approved replacement partonly.

5) Do not operate the Hole Digger without the properhandle reinforcement properly attached to the

transmission case sockets.

Handle reinforcements provide properstructural integrity. Use of the Hole Diggerwithout the proper operator handlereinforcement can result in handle failureand/or personal injury.

6) Do not utilize chains or slings wrapped around thecomposite material operator handles to help remove aHole Digger which has become stuck in the ground.


23/69


USE OF CHAINS AND/OR SLINGS WRAPPEDAROUND THE COMPOSITE MATERIALOPERATOR HANDLES TO HELP REMOVE AHOLE DIGGER FROM THE GROUND CANRESULT IN DAMAGE TO THE HANDLES ANDTRANSMISSION. THIS OCCURRENCE CANLEAD TO PROPERTY DAMAGE AND/ORPERSONAL INJURY.

7) Regardless of actual use, all compositematerial operator handles have a maximumservice life of 6 years. Replace any handlesubject to this time limit with a factory approvedreplacement par t onl y.

OPERATION OF A HOLE DIGGER WITHOPERATOR HANDLES NOT MEETING THEDESCRIBED REQUIREMENTS AND/OROPERATING PARAMETERS CAN RESULTIN PROPERTY DAMAGE AND/ORPERSONAL INJURY.

GENERAL TRANSPORTATION INFORMATION.


When transporting the Hole Digger in/on a motorvehicle, the gasoline tank breather vent (if so equipped)must be completely closed to eliminate the accidental

seepage of fuel and resulting potential fire hazard. Inorder to minimize the possibility of damage to the HoleDigger, always transport it to the job site with the augerdisconnected. Failure to properly transport the HoleDigger can cause transmission oil to becomeentrapped in the centrifugal clutch drum. Such anoccurrence can cause excessive clutch slippage untilthe oil properly drains. All equipment must be securedin/on vehicles with suitable strapping or tie downs.Personnel should not be transported in the samecompartment as equipment and fuel supplies. Consultapplicable OSHA regulations.

DETERMINATION OF POTENTIALSUBSURFACE HAZARDS IN THE PROPOSEDDIGGING LOCATION(S).


BEFORE ATTEMPTING TO DIG WITH THE HOLEDIGGER, DETERMINE THE POTENTIALSUBSURFACE HAZARDS THAT MAY EXIST IN THEPROPOSED DIGGING LOCATION(S). POTENTIALSUBSURFACE HAZARDS MAY INCLUDE, BUT NOTBE LIMITED TO, THE FOLLOWING:

1) ROCKS OF ANY SIZE.2) ROOTS OF ANY SIZE.3) BURIED MATERIALS SUCH AS GARBAGEAND OTHER DEBRIS.4) BURIED PRESSURIZED PIPELINESCONTAINING SUCH MATERIALS AS NATURAL

GAS, PROPANE, ETC.5) BURIED ELECTRICAL CABLES.

BEFORE ATTEMPTING TO DIG WITH THE HOLEDIGGER IN THE PROPOSED LOCATION(S),CONTACT ALL APPROPRIATE AGENCIES TODETERMINE THE EXACT LOCATION(S) OF ALLBURIED PIPELINES, POWER LINES ANDMATERIAL DEBRIS. MANY UTILITIES ANDOTHER AGENCIES WILL PERFORM THESETASK AT MINIMAL CHARGE OR NO COST.

HAVE ALL SUBSURFACE HAZARDS MARKEDFOR EASY RECOGNITION. MACHINECONTACT WITH THESE AND OTHERSUBSURFACE HAZARDS CAN RESULT INPROPERTY DAMAGE AND/OR PERSONALINJURY.

SETUPFORDIGGING.


1) The Hole Digger is designed for two operators totransport it by the operator handles to, while on, andfrom the job site. Connect the auger to the Hole Digger

with the correct factory supplied auger pin. Dependingupon the specific model, a variance in auger pin partnumber and design configuration exists. Models 330Hand 357H utilize the 3/8 inch (9.5mm) diameter, PN2121 auger pin. Model 343H utilizes the 5/16 inch (8mm) diameter, PN 2021 auger pin.FIGURE 10.


24/69


FIGURE 10

When installing the auger and auger pin,always place the Hole Digger with the enginespark plug in the upward position to minimizethe potential for gravity to allow oil and/orgasoline to enter into the combustionchamber and create a hydraulic lock up. Suchan occurrence can result in property damageand/or personnel injury.

The auger pin supplied with the Hole Digger

is designed to withstand the high stressesencountered while digging. Use of any otherconnecting device, including cap screws,bolts, pins, etc., can result in damage to theHole Digger driveshaft and/or auger drivehub. Improper connecting devices can causeproperty damage and/or personal injury.

DO NOT CONNECT THE AUGER TO THE HOLEDIGGER WITH THE ENGINE RUNNING. ASUDDEN AND/OR UNEXPECTED CHANGE IN

THE ENGINE SPEED CAN RESULT INPROPERTY DAMAGE AND/OR PERSONALINJURY.

THE HOLE DIGGER IS DESIGNED FOR TWOMAN OPERATION. USE BY ONLY ONEOPERATOR OR BY MORE THAN TWOOPERATORS WILL LEAD TO CONFUSION AND

LOSS OF CONTROL, RESULTING INPROPERTY DAMAGE AND/OR PERSONALINJURY. THE CONTROLS ARE DESIGNED FORONE OPERATOR (CREW MEMBER) TO STARTTHE ENGINE AND OPERATE THE ENGINECHOKE CONTROL WHILE THE OTHEROPERATOR (CREW CHIEF) HELPS MAINTAINMACHINE STABILITY AND REGULATES

ENGINE SPEED WITH THE TWIST GRIPTHROTTLE CONTROL.

STARTING THE ENGINE WITH THE AUGERATTACHED.

Application: 330H, 343H and 357H Hole Diggerspowered by the Honda GXV160 engine.

1) Grass and other overgrowth conditions will hamperthe digging characteristics of any earth auger bybecoming "clogged" around the auger teeth and screwbit. Removal of such obstructions from the hole locationbefore attempting to dig will increase digging efficiency

and overall productivity.

2) Place the Hole Digger in a vertical orientation on thedesired hole location. The operators should positionthemselves on firm footing.

3) The Crew Chief opens the fuel tank breather vent (ifso equipped) to its maximum set position. Failure toproperly open the breather vent will prevent the enginefrom receiving a continuous supply of fuel.

4) The Crew Member opens the fuel tank ON/OFFvalve located under the fuel tank to the ON position.FIGURE 11.

FIGURE 11


25/69


5) The Crew Chief operates the throttle control with hisright hand and provides machine stability while holdingthe remaining handle with his left hand. The Crew Chiefrotates the throttle control counterclockwise (to open)half way against its stop. The Crew Member closes theengine choke by pulling the control lever located abovethe carburetor out to its detent position. FIGURE 12.

FIGURE 12

Do not apply excessive force when pulling orpushing the choke control lever. Excessiveforce can damage the carburetor.

6) The Crew Member pulls the recoil starter handle until

engine compression is felt. Then he gives a fast, short,steady pull. Allow the starter rope to retract slowly. Ifthe engine does not start in three pulls, consult thematerial supplied by the engine manufacturer forspecific information. As the engine warms up, the CrewMember pushes the choke lever in to its detent position.

7) Normally, an engine that has not been run for sometime requires three to five pulls before it will fire. On theother hand, a recently run engine will usually start onthe first or second pull. In cold weather, initial startingwill require additional pulls because an extremely richfuel/air mixture is required.

8) Allow the engine to properly "warm up" and operatewithout the requirement for engine choke. Check forproper centrifugal clutch operation, excessivetransmission noise and/or vibration.

9) Stopping the Hole Digger is accomplished byrotating the twist grip throttle control clockwise to itsmaximum, closed position and allowing the throttle armto engage the ignition cut-off switch. FIGURE 13.

OPERATING THE HOLE DIGGER.


1) Do not attempt to begin digging with the Hole Diggeruntil both the Crew Chief and Crew Member haveacknowledged to each other that they are ready andare in full control of the machine.

2) The Crew Chief rotates the throttle controlcounterclockwise to increase the engine speed. Theauger will begin to rotate when the engine speedreaches the centrifugal clutch initial engagementspeed.

3) Normal operating procedure for the Hole Digger is todig with the engine operating at full, governed speed toallow the centrifugal clutch to become more firmlyengaged. This procedure will transmit more usablepower to the auger, resulting in greater productivity andless component wear.


26/69


When digging in areas filled with known,buried obstructions such as tree roots,rocks and other debris, operate the HoleDigger at less than full , governed (anintermediate) speed to insure a more rapidrelease of the centrifugal clutch when anobstruct ion is encountered. This is anindustry wide operating procedure.

4) The Hole Digger is equipped with a centrifugal clutchassembly within the transmission. Newton's Law ofPhysics allow the centrifugal clutch assembly toALWAYS slip (NOT DISENGAGE) wheneveroverloaded or if the auger comes in contact with aburied obstruction. The term slippage is not intended toinfer that the centrifugal clutch assembly becomes fullydisengaged with no horsepower and torque beingtransmitted to the auger. In the slipping mode, acentrifugal clutch still transmits a specific amount ofhorsepower and torque to the auger. This specificamount of horsepower and torque is directlyproportional to many factors including: the mechanicalcondition of the centrifugal clutch assembly and therotational speed of the centrifugal clutch assemblywhen the initial slippage occurs. The response time forthe centrifugal clutch assembly to react to an overloadcondition is directly proportional to its rotational speed.The higher the rotational speed (RPM) of thecentrifugal clutch at the time of overload, the greateramount of time it requires to react and actually slip. Thisphenomenon is inherent with all centrifugal clutchassemblies. It is inherent with all powered equipment

incorporating such a device.

STRIKING BURIED OBSTRUCTIONS SUCH AS

TREE ROOTS, ROCKS AND OTHER DEBRIS AT

ANY SPECIFIC ENGINE OPERATING SPEED CAN

CAUSE THE HOLE DIGGER TO TRANSMIT

REACTIONARY TYPE "IMPACT" LOADS TO THE

OPERATORS. THESE TYPES OF LOADS ARE

CHARACTERIZED BY A SHARP, PULSATING

MOVEMENT OF THE HOLE DIGGER IN A

COUNTERCLOCKWISE DIRECTION (AS VIEWEDBY THE OPERATOR). SUCH LOADS CAN LEAD TO

THE LOSS OF OPERATOR CONTROL AND RESULT

IN PERSONAL INJURY. THE OPERATIONAL

EFFECTS ARE ALIKE TO THAT OF UTILIZING A

COMMON ELECTRIC DRILL AND OTHER,

ROTATION TYPE, POWERED EQUIPMENT. THE

RELATED PHENOMENON IS INHERENT WITH ALL

SUCH TYPES OF ROTATION TYPE, POWERED

EQUIPMENT AND IS TERMED AS KICKBACK.

UNDERSTANDING KICKBACK.


The operation of the Hole Digger involves enginetorque being transmitted and multiplied by thetransmission to the auger. The energy is then used todig holes. But to every force (action), there is always areaction force in the opposite direction. Thus, if theauger contacts a buried obstruction, the operators willfeel the left side handles of the Hole Digger being"thrusted" towards them. This "thrusting" forceexperienced by the operators is called kickback. Thespeed (and magnitude of the resulting impact force) atwhich the auger strikes the buried object is directlyproportional to the amount/speed of the kickback forceexperienced by the operators. The torque and kickbackgenerated by the digging process is inherent with aportable, two man Hole Digger and can not beeliminated by any operation and/or designcharacteristic. The operational effects are alike to thatof utilizing a common, electric drill and other, rotation

type, powered tools.BACKCARE/PROPERLIFTINGINFORMATION


In addition to kickback forces encountered during thehole digging process, the operator will be required to lift

the Hole Digger and auger/auger extension withnumerous repetition, as demanded by the specific job

application. Utilizing proper lifting techniques willminimize fatigue and back-related injuries whileincreasing overall productivity rates.

ANATOMY

The human body is supported by the spinal column.

The spinal column consists of thirty separate bonescalled vertebrae, all linked and supported by a series of

tiny muscles. Small pads called discs are situatedbetween each vertebrae and act like shock absorbersto cushion the pressure created from external forces.

The spinal column is wrapped by a system of nervesand has three natural curves:

Cervical: from the base of the neck to the brain.

Thoracic: situated from the middle to the lower back.Lumbar: located from the lower back to the buttocksarea.

These three curves need to be kept in natural

alignment in order to prevent discomfort.


27/69


PREVENTATIVE MEASURES

Most occupational physicians agree on severaluniversal preventative measures that an operator

should follow to help lower the risk of back-relatedinjuries:

1) Maintain proper body weight.

2) Maintain good posture while walking or sitting.

3) Be conscious of how you twist and bend your bodywhile digging. Twisting and bending the wrong way can

exert too much pressure on one side of your vertebrae.

4) Always use proper lifting techniques as described

below.

5) Develop a consistent exercise routine.

6) Eliminate or reduce your use of tobacco. Smokingreduces the supply of oxygen and nutrients to the discsthat cushion the vertebrae.

PROPER LIFTING PROCEDURES

The following are guidelines for properly lifting the Hole

digger and auger/auger extension from the hole andare not intended to be all inclusive.Plan your path and

make sure there are no obstructions or trippinghazards. Consider how you will set the load. The spinalcolumn is a very sensitive mechanism. At any given

time, improper lifting procedures can cause damage

that can lead to injury.

1) Position your feet at a comfortable distance

(shoulder width) to help provide the necessarybalance.

2) Tighten your stomach muscles by pulling in yourstomach. Keep your back as straight as possible to

keep the spine, back muscles and ligaments in correctalignment.

3) Remember to bend at the hips and knees as muchas possible.

4) Start lifting the Hole Digger with a thrust of your feet

while lifting as much as possible with your leg muscles.Use smooth movements.

5) Once you lift the Hole Digger, keep it close aspossible to the body. Avoid turning at the waist. To turn,

pivot your entire body.

6) Keep your shoulders, hips and feet pointed in thesame direction.

7) Keep your footing firm and make sure that your

intended path is clear before attempting to carry theHole Digger.

MINIMIZING KICKBACK FROM AN OPERATIONAL

STANDPOINT.


Both operators should keep the left side handle asclose to their body (left hip and leg areas) as possibleto minimize machine "kickback" when a buriedobstruction is encountered by the auger. Assumeoperating positions that allow each to exercise reactive"body english" against the torque sensation created bythe digging process. Keep upper arms as close to theupper body as possible to maximize mechanicalleverage. Operators should position their backs asvertical as possible by bending the legs as required

during the digging process. Positioning the left footahead of the right foot will enhance proper bodyposition. Maintaining proper operating positions is oneof the most IMPORTANT and EFFECTIVE proceduresfor controlling kickback. Improper operating positionsonly aggravate the effects of kickback upon theoperators. FIGURE 14 depicts proper operatorpositions that enhance machine control. FIGURES 15,16 and 17 depict improper operator positions thatreduce machine control .

Keep a firm, but steady, grip on the operator handles.Wrap your fingers around the handle grips, keeping thegrips cradled between the thumbs and forefingers.REMEMBER PROPER OPERATOR POSITIONSENHANCE THE CONTROL OF THE HOLE DIGGER,REDUCE OPERATOR FATIGUE AND INCREASEOVERALL PRODUCTIVITY.

Maintain the operator handles and grips ingood condition and free of moisture, pitch oilor grease. Wear gloves to improve your grip.Bent or damaged handles, or handles withdamaged and worn and/or without gripsaggravate the effects of kickback upon theoperators by limiting control and comfort.Handle grips should be repaired and/orreplaced when they become worn and/ordamaged from use. Do not operate the HoleDigger until such handles are repaired and/orreplaced. Damage to property and/or personalinjury can result.

Always assume that every digging site caninclude some form of buried obstruction.Always be prepared for unexpected augercontact with buried tree roots, rocks, etc.Under certain operating conditions, striking aburied obstruction can produce a severeand/or sudden kickback force to the hipand/or leg areas. Operators must maintainphysical and mental alertness and beprepared to accommodate this phenomenon.Failure to properly accommodate thisphenomenon can result in property damageand/or personal injury.

IF, DURING THE HOLEDIGGINGPROCESS, THEOPERATOR LOOSES FULL CONTROL OF THEHOLE DIGGER FOR ANY REASON, THEFOLLOWING PROCEDURE ISSUGGESTED:

AS A GENERAL RULE, AS SOON AS THE

OPERATORS REALIZE THEYARE IN THE

PROCESS OF LOOSING FULL CONTROL OF THE

HOLE DIGGER, THEY SHOULD "PUSH"

THEMSELVES FREE AND CLEAR FROM THE

OPERATOR HANDLES. THE PROCEDURE

REQUIRES THE OPERATORS TO FULLY

COMPREHEND THEYARE LOOSING CONTROL OF

THE HOLE DIGGER AND TO REACT ACCORDINGLY

WITH APPROPRIATE BODY MOVEMENT.

IMPROPER REACTIONS TO THIS PHENOMENON

CAN RESULT IN PROPERTY DAMAGE AND/OR

PERSONAL INJURY.

A HOLE DIGGER WITH AN IMPROPERLY

MAINTAINED ENGINE THROTTLE CONTROL WILL

"SPIN" ABOUT ITS AXIS WHEN THE OPERATORS

LOOSE FULL CONTROL. IN THE EVENT OF THIS

OCCURRENCE, DO NOT ATTEMPT TO STOP THE

ENGINE BY GRASPING THE ROTATING OPERATOR

HANDLES. DO NOT INTRODUCE ANY FOREIGN

OBJECT IN AN ATTEMPT TO STOP AND/OR BLOCK

THE ROTATING HANDLES. INSTEAD, ALLOW THE

ENGINE TO EXHAUST ITS FUEL SUPPLY.

DETERMINE THAT ALL COMPONENTS OF THE

ENGINE THROTTLE CONTROL ASSEMBLY ALLOW

FOR PROPER FUNCTION BEFORE ATTEMPTING

TO FURTHER UTILIZE THE HOLE DIGGER.

MINIMIZING KICKBACK FROM A DESIGNSTANDPOINT.


1) The Hole Digger features the longest operatorhandles of any machine of its type and/or class. Thesehandles are biomechanically positioned to enhancecontrol by allowing the operators to exert "bodyenglish" against the torque and kickback forcesgenerated by the digging process.

2) The Hole Digger utilizes antivibration handle grips onthe operator handles to enhance control and helpdampen the torque and kickback experienced by theoperators during the digging process.

Do not operate the Hole Digger if the handlegrips are worn and/or damaged from use.Replace the handle grips with factoryapproved replacement par ts only.

3) The Hole Digger features operator handles

constructed of a non metallic, composite material. Thephysical characteristics of this material allow it to helpdampen the torque and kickback experienced by theoperators during the digging process.

4) The Hole Digger utilizes a twist grip throttle control.This type of throttle control device was selected overother configurations (for the operator handleconfiguration utilized and specific digging power)because it allows the operator to wrap his thumb

around the forefinger and effectively maximize thestrength in his right hand. This design feature affordsthe operator greater control of the machine whencounteracting the effects of torque and kickback forcesduring the digging process.

5) The Hole Digger is designed to utilize the GeneralEquipment Company part number 2021 or 2121 auger

pin to retain the earth auger to the transmissiondriveshaft. This pin is not intended to shear when theauger comes in sudden contact with a buried object.

The pins are utilized for the following reasons:

a) Such an occurrence (pin shear) would result inextensive physical damage to the driveshaft and augerdrive hub.

b) Even if the physical damage to the Hole Digger couldbe eliminate and/or minimized from the actualprocesses, it could require an unknown (and potentiallylarge) number of auger pins to complete the digging

process for any specific hole.

c) Even if the cost of the replacement auger pins is nota factor, the resulting productivity produced by theactual process would not be deemed acceptable byindustry and/or social standards for the Hole Digger.

d) Given the infinite number of soil conditions whichcould be encountered during the actual process, it isimpossible to design and supply a specific auger pin toshear at a specific torque value which would produceacceptable operational results for the Hole Digger.

e) Given the infinite number of operators and their

methods utilized during the actual process, it isimpossible to design and supply a specific auger pin toshear at a specific torque value which would produceacceptable operational results for the Hole Digger.

f) Given the infinite number of combinations of soilconditions, auger diameter, auger boring headcondition, digging depth, mechanical operatingcondition, operators and operator methodsencountered during the actual process, it is impossibleto design and supply a specific torque value whichwould produce acceptable operational results for theHole Digger.

6) For comparison purposes, it is interesting to notethat portable electric drills do not utilize any torquelimiting or clutch device to allow the drill bit to slip at anspecific torque value for drilling purposes. As with aHole Digger, such a devise would make the drill auseless tool because of the infinite number of potentialoperating configurations and the inability to designspecific components to meet the requirements of eachoperating configuration.7) Many portable electric screwdrivers incorporate a

effects of kickback being generated by the auger teethcontacting the object. As with any hole diggingprocedure, the mechanics of this technique require theaccumulation of actual experience and common senseto maximize its effectiveness. Many times the size andnature of a buried object will simply prevent the augerfrom passing by or going through it. Continued diggingwith the Hole Digger will only contribute to equipment

damage operator fatigue and/or injury. Instead, removethe buried object with a shovel or other suitable tooland proceed to dig the hole with the Hole Digger to thedesired depth.

Some job appl icat ions may encounterburied obstructions that are too massive insize to allow the usage of a machine thesize and/or with the operat inglimitations of the Hole Digger. Utilization ofthe Hole Digger on these work sites can

cause property damage and/or personalinjury. Exercise proper common sense byselecting the proper size and/or type ofequipment for the job application.

Some job applications may encounter soilclassifications that are too compacted toallow the usage of a machine the sizeand/or with the operating limitations of theHole Digger. Utilization of the Hole Diggeron these work sites can cause property

damage and/or personal injury. Exerciseproper common sense by select ing theproper size and/or type of equipment forthe job application.

8) In most soil conditions, the auger will retract withless effort if allowed to rotate at a slow speed. Thisprocedure, however, will leave more loose soil at thebottom of the hole. To minimize the amount of loose soilthat remains at the bottom of the hole, stop the rotationbefore retracting the auger. Proper procedure forobtaining the cleanest, most usable hole for any givensoil condition requires the accumulation of actual skill,experience and common sense.

9) The twist grip throttle controls the digging process byregulating the engine speed. Keep a firm grip on it at alltimes. As with any safety device, it requires constantand proper maintenance to function as intended.

10) Attempting to restart the engine with the auger in apartially or completely dug hole requires extra caution.In this configuration, the throttle control can beadvanced beyond the idle speed position before thetwo operators can exercise proper control of the Hole

Digger. The more accepted procedure (when notutilizing both nonflighted and/or full flighted augerextensions) is to first remove the unit from the hole andrestart the engine according to the described method.Return the unit to the hole with the engine running atidle speed and proceed to complete the hole to thedesired depth.

Restarting the engine with the auger in apartially or completely dug hole requires ahigher degree of operator experience, skilland common sense over that of anintroductory or novice level of expertise.The manufacturer is aware that manyoperators restart the Hole Digger's enginewith the auger in a partially or completelydug hole on a regular basis while in thefield. The manufacturer also realizes thatthis procedure must be utilized when auger

extensions are ut i l ized to extend thedigging depth. The manufacturer has nocontrol over the experience, skil l andcommon sense levels of each operator ofthe Hole Digger.The manufacturer has nocontrol over each job site or specific jobapplication for the Hole Digger.

Individual operator experience, ski l l ,common sense, job si te locat ion andspecific job application must affect the

f inal decision on speci f ic operat ingprocedures for the Hole Digger. Eachoperator must decide i f he possessesadequate/proper experience, skil l andcommon sense for operat ing the HoleDigger in any given and/or specific jobapplication.

11) Both the auger teeth and screw bit must bereplaced when signs of excessive wear are visible. Aregularly scheduled maintenance program will increasethe service life of the auger and increase productivityby substantially reducing operator fatigue. An augerrequiring replacement of the auger teeth and screw bit

is depicted in FIGURE 18.

FIGURE 18

Do not utilize an auger with the auger teethand screw bit worn past their specificservice limits. Excessive wear to the augerteeth and screw bit will allow the augerflighting to wear in a tapered or invertedcone configuration. The worn boring headmay actually be only capable of digging ahole 60 to 75 percent the nominal diameterof the auger. This configuration will allowthe auger to "bind" within the hole andsubstantially reduce operator control andproductivity.

12) Avoid placing serious stress to the back and otherlower body members. Always lift in a straight line withyour legs. Maintain the back in a vertical position asallowed by the digging process. Proper wrist positionduring the digging process can minimize and/or reducestress and strain related damage potential to this bodyarea. Operator control can be enhanced and fatiguereduced by attempting to keep wrists as perpendicularto the operator handles as feasible during the diggingprocess. See BACK CARE/PROPER LIFTINGINFORMATION. FIGURE 19.

13) Stop the engine between each hole to minimize thepossibility of personal injury. Special care must beexercised in slippery conditions and in difficult,overgrown terrain to minimize any tr ip and fall potential.This can be accomplished with good communicationbetween the Crew Chief and Crew Operator, properattire, including shoes and the removal of any trip andfall hazard BEFORE attempting to utilize the HoleDigger on the job site.

TO REDUCE THE POTENTIAL FORPERSONAL INJURY, STOP THE HOLEDIGGER BETWEEN EACH HOLE. DO NOT

CHOOSE TO SAVE TIME (THE TIMEREQUIRED TO RESTART THE ENGINE),MONEY (IN THE EVENT THE HOLE DIGGERIS BEING RENTED) ORTHEADDEDCONVENIENCE BY ELECTING TO KEEP THEENGINE RUNNING BETWEEN EACH HOLE.SUCH OCCURRENCE CAN LEAD TO LOSSOF CONTROL, RESULTING IN PROPERTYDAMAGE AND/OR PERSONAL INJURY.

STOPPINGTHEHOLEDIGGER.


1) Stopping the Hole Digger is accomplished byrotating the twist grip throttle control clockwise to itsmaximum, closed opposition and allowing the throttlearm to engage the ignition cut-off switch. With thethrottle control functioning properly, the engine can bebrought to the specific idle speed, the auger rotationstopped (there may be some slight rotation due toviscous drag within the centrifugal clutch assembly. Theclutch is NOT engaged.) and the ignition cut off whenthe throttle control is released or fully closed. If this isnot taking place, or the ignition cut-off switch can not be


33/69


engaged with throttle control movement, check thethrottle control and throttle cable for binding and/orimproper adjustment.

2) When the engine is not in operation, turn the fueltank ON/OFF valve to the OFF position to minimize thepotential for fuel flooding the carburetor and/or enteringthe engine crankcase and/or impacting upon the

environment.

TEMPORARY STORAGE FOR THE HOLE DIGGERWHILE ON THE JOB SITE.

Applications: All 300 Series models.

The Hole Digger can be temporarily stored on the jobsite by one of three acceptable methods as determinedby the operators based upon personal preferenceand/or job site conditions:

a) Digging a shallow hole and leaving the Hole Diggerconnected to the auger. FIGURE 20.

FIGURE 20

b) Disconnecting the Hole Digger from the augerand/or auger extension(s) and storing it in a levelconfiguration. FIGURE 21.

c) Storing the Hole Digger while connected only to alead auger with the engine spark plug facing upward.The Hole Digger is powered by a four cycle engine.

This storage configuration will minimize the potentialfor crankcase oil entering the combustion chamber andcausing a hydraulic lock up. FIGURE 22.

ADDING AND REMOVING NONFLIGHTED ANDFULL FLIGHTED AUGER EXTENSIONS.


While this text covers the use of all 300Series Hole Diggers during the adding andremoving of nonflighted and full flightedauger extensions, several variances existbetween various models with the applicableengine start and stop procedures. Consultthe applicable STARTINGTHEENGINEWITHTHEAUGERATTACHED for specificinformation.

Many digging applications require a hole deeper thanthat provided by standard length augers. For suchrequirements, both nonflighted and full flighted augerextensions are available. The nonflighted augerextension extends the digging depth by an additional 15inches (381 mm). Full flighted auger extensions areavailable in diameters up to 12 inches (305 mm) andeach with a standard 36 inch (914 mm) length.

Utilization of nonflighted and full flightedauger extensions requires addit ionaloperator experience, skil l and commonsense over that of an introductory or

novice level of expertise. The manufacturerhas no control over the experience, skilland common sense levels of each operatorof the Hole Digger. Uti l ization ofnonf l ighted and ful l f l ighted augerextensions requires the accumulation ofactual hole digging experience, skill andcommon sense. Each operator must decideif his experience, skill and common senselevel is sufficient to allow him to proceedwith the utilization of nonflighted and full

f l ighted auger extensions for any givenand/or specific job application.

Follow this accepted procedure for utilizing bothnonflighted and full flighted auger extensions to extendthe digging depth:

1) Dig to the approximate full depth of the auger,utilizing the described operating instructions. Removeas much loose soil from the hole as possible with theauger rotating at a lower rotational speed.

2) STOP the engine and remove the auger from thehole. Disconnect the spark plug wire to preventaccidental engine starting. Close the fuel tank breathervent (if so equipped). Turn the fuel tank ON/OFF valveto the OFF position.

3) Disconnect and remove the Hole Digger from theauger. Reposition the auger in the hole. Attach theauger extension to the auger and secure with an augerpin. The Hole Digger can now be connected to theauger extension and secured with an auger pin.Reconnect the spark plug wire.

4) Follow the instructions outlined for starting andoperating the Hole Digger. Use extra caution whenstarting the engine with the auger in the hole. Proceedto dig to the desired depth or to the full depth of theauger extension. FIGURE 23.

5) Use of the nonflighted auger extension to extend thedigging depth is limited to one unit. For multiple use offull flighted auger extension, repeat the aboveprocedure until the desired digging depth is achieved.

FIGURE 23


35/69


NEVER UTILIZE MORE THAN ONENONFLIGHTED AUGER EXTENSION TOINCREASE THE OVERALL DIGGING DEPTH.THE NONFLIGHTED AUGER EXTENSION ISNOT EQUIPPED WITH AUGER FLIG HTING TO

ELEVATE THE LOOSE BORINGS FROM THEHOLE. CONSEQUENTLY, MULTIPLE USE OFNONFLIGHT ED AUGER EXTENSIONSWILL ALLOW THE AUGER TO BURYITSELF IN THE HOLE. SUCH USE CAN LEADTO LOSS OF OPERATOR CONTROL ANDPERSONAL INJURY WHILE DIGGING.

After the desired digging depth has beenachieved, both nonflighted and full f l ightedauger extensions are removed by util izing thisaccepted procedure:

1) Remove as much loose soil from the hole aspossible with the auger rotating at an intermediatespeed. STOP the engine and disconnect the spark plugwire to prevent accidental engine starting. Close thefuel tank breather vent (if so equipped). Turn the fueltank ON/OFF valve to the OFF position.

2) Lift the auger extension(s)/auger and the HoleDigger up far enough out of the hole so that an augerextension is clear. Block the remaining auger/augerextension string with an auger fork to prevent it fromfalling back into the hole. An additional Crew Memberwill usually be required. Disconnect the Hole Diggerfrom the auger extension(s)/auger. Store on the job siteas outlined above. Remove the auger extension fromthe auger/auger extension string. FIGURE 24.

FIGURE 24

3) Disconnect the Hole Digger from the blocked augerextension(s)/auger string. Store the Hole Digger on the

job site as outlined. Remove the auger extension that isclear of the hole from the auger extension(s)/augerstring.

4) Reconnect the Hole Digger to the remaining augerextension(s)/auger string. Repeat the process until thelead auger is recovered.

5) Reconnect the engine spark plug wire.

THE PROCEDURE OUTLINED FOR THE USE OFBOTH NONFLIGHTED AND FULL FLIGHTEDAUGER EXTENSIONS OFFERS THE MOSTADAPTABLE METHOD OF EXTENDING THEDIGGING DEPTH FOR THE WIDEST CROSSSECTION OF PROBABLE OPERATORS. THISPROCEDURE TAKES INTO ACCOUNTANTICIPATED OPERATOR EXPERIENCE, SKILLAND COMMON SENSE. THE MANUFACTURER IS

AWARE THAT NOT ALL OPERATORS WILL ELECTTO FOLLOW THIS PROCEDURE. THEMANUFACTURER HAS NO CONTROL OVERINDIVIDUAL OPERATING PROCEDURES AND/ORDECISION
