OPERATEYOURSAWSAFELY• Do not operate with one hand. Seri-

ous injury to the operator, helpers, orbystanders may result from one-handed operation. A chain saw is in-tended for two-handed use.

• Operate the chain saw only in a welt-ventilated outdoor area.

• Do not operate saw from a ladder orin a tree, unless you are specificallytrained to do so.

• Make sure the chain will not makecontact with any object while startingthe engine. Never try to start the sawwhen the guide bar is in a cut.

• Do not put pressure on the saw, es-pecially at the end of the cut. Doingso can cause you to lose controlwhen the cut is completed,

• Stop engine before setting sawdown.

• Hand carry saw only when engine isstopped. Carry with muffler awayfrom body; guide bar & chain project-ing behind you; guide bar preferablycovered with a scabbard.

MAINTAIN YOUR SAW tN GOODWORKING ORDER• Have all chain saw service per-

formed by a quaIified service dealerexcept the items listed in the mainte-nance section of this manual.

• Make certain the saw chain stopsmoving when the throttle trigger isreleased. For correction, refer toCARBURETOR ADJUSTMENTS.

• Keep the handles dry, clean, andfree from oil or fuel mixture.

• Keep caps and fasteners securelytightened.

• Use only Craftsman accessories andreplacement parts as recommended.Never modify your saw.

HANDLE FUEL WITH CAUTION• Do not smoke while handIing fuel or

while operating the saw.• Eliminate all sources of sparks or

flame in areas where fuel is mixed orpoured.

• Mix and pour fueI in an outdoor areaand use an approved, marked con-tainer for all fuet purposes. Wipe upatl fuel spilis before starting saw.

• Move at least 10 feet (3 meters) fromfueiing site before starting.

• Turn the engine off and tet saw cootin a non-combustible area, not on

dry leaves, straw, paper, etc, Slowlyremove fuet cap and refuet unit.

• Store the unit and fuel in a coot, drywell ventilated space where fuel va-pors cannot reach sparks or openflames from water heaters, electricmotors or switches, furnaces, etc.

GUARD AGAINST KICKBACKFollow all safety rules to help avoidkickback and other forces which can

result in serious injury.

Clear The Working Area

A0&WARNING: Rotational Kickback

can occur when the moving chain con-tacts an object at the upper portion ofthe tip of the guide bar, Contact at theupper portion of the tip of the guide barcan cause the chain to dig into the ob-ject, which stops the chain for aninstant. The result is a lightning fast,reverse reaction which kicks the guidebar up and back toward the operator.Pinch-Kickback and Pull-In occur

when the chain is suddenly stopped bybeing pinched, caught, or by contact-ing a foreign object in the wood. Thissudden stopping of the chain results ina reversat of the chain force used tocut wood and causes the saw to movein the opposite direction of the chainrotation. Pinch-Kickback drives thesaw straight back toward the operator.Putt-In pulls the saw away from the op-erator.REDUCE THE CHANCE OFKICKBACK• Recognize that kickback can happen.

With a basic understanding of kick-back, you can reduce the element ofsurprise which contributes to acci-dents.

• Never tet the moving chain contact

• any object at the tip of the guide bar.Keep working area free from obstruc-tions such as other trees, branches,

rocks,fences,stumps,etc.Eliminateoravoidanyobstructionthatyoursawchaincouldhitwhilecutting.

• Keepsawchainsharpandproperlytensioned.Alooseordullchaincanincreasethechanceofkickback.Followmanufacturer'schainsharp-eningandmaintenanceinstructions.Checktensionatregularintervals,butneverwithenginerunning.Makesurebarclampnutsaresecurelytightened.

• Beginandcontinuecuttingatfuitspeed.Ifthechainismovingataslowerspeed,thereisgreaterchanceofkickbackoccurring.

• Useextremecautionwhenreenter-ingacut.

• Donotattemptcutsstartingwiththetipofthebar(ptungecuts),

• Watchforshiftinglogsorotherforcesthatcouldcloseacutandpinchorfallintochain.

• UsethespecifiedReduced-KickbackGuideBarandLow-KickbackChain.

Avoid Pinch-Kickback:• Be extremely aware of situations or

obstructions that can cause materialto pinch the top of or otherwise stopthe chain.

• Do not cut more than one tog at atime.

• Do not twist saw as bar is withdrawnfrom an undercut when bucking.

Avoid Pull-In:• Always begin cutting with the engine

at full speed and the saw housingagainst wood.

• Use wedges made of plastic orwood, Never use metal to hold thecut open.

MAINTAIN CONTROLStand to the left of the saw

Thumb on \[underside

of handlebar

Never reverse h'_nd'positions locked

• A good, firm grip on the saw withboth hands will help you maintaincontrol. Don't let go. Grip the rearhandle with your right hand whetheryou are right or left handed. Wrap thefingers of your left hand over andaround the front handlebar, and your

left thumb under the front handlebar.Keep your left arm straight with theelbow locked.

• Position your left hand on the fronthandlebar so it is in a straight linewith your right hand on the rear han-dle when making bucking cuts.Stand slightly to the left side of thesaw to keep your body from being ina direct line with the cutting chain.

• Stand with your weight evenly bal-anced on both feet.

• Do not overreach. You could bedrawn or thrown off balance and losecontrol.

• Do not cut above shoulder height. Itis difficult to maintain control of sawabove shoulder height.

KICKBACK SAFETY FEATURES

'_I'WARNING: The following fea-tures are included on your saw to helpreduce hazard of kickback; however,such features will not totally eliminatethis danger. Do not rely only on safetydevices.

• Handguard: designed to reduce thechance of your left hand contactingthe chain if your hand slips off thefront handlebar.

• Position of front and rear handlebars:designed with distance betweenhandles and "in-line" with each other.The spread and "in-line" position ofthe hands provided by this designwork together to give balance andresistance in controlling the pivot ofthe saw back toward the operator ifkickback occurs.

• Reduced-Kickback Guide Bar: de-signed with a small radius tip whichreduces the size of the kickbackdanger zone. This type bar has beendemonstrated to significantly reducethe number and seriousness of kick-backs when tested in accordancewith ANSI B175.1.

Seek help fromsomeone that does understand the in-formation or cati the customer assis-tance help line at 1-800-235-5878.

GUIDE BAR AND CHAIN OILThe chain oiler provides continuouslubrication to the chain and guide bar.Be sure to fitI the bar oil tank when youflit the fuet tank (Capacity = 6.8 ft. oz.).For maximum guide bar and chain life,we recommend you use Craftsmanchain saw bar oil. If Craftsman bar oit

is not available, you may use a goodgrade SAE 30 oil untit you are aMe toobtain Craftsman brand. The oil outputis automatically metered during opera-tion. Your saw will use approximatelyone tank of bar oil for every tank of fuelmix. Always fill the bar oit tank whenyou fill the fueI tank.

FUELING ENGINEThis engine is certified to operate onunIeaded gasoIine. Before operation,gasotine must be mixed with a goodquality 2-cycte air-cooled engine oil.We recommend Craftsman brand oilMix gasoline and oil at a ratio of 40:1(A 40:1 ratio is obtained by mixing 3.2ounces of oil with 1 gailon of unleadedgasoline). DO NOT USE automotive oilor boat oil These oils will cause

engine damage. When mixing fuelfollow the instructions printed on thecontainer.Once oiI is added to the gasoline,shake container momentarily to assurethat the fuel is thoroughly mixed.Always read and foltow the safety ruIesrelating to fuel before fueling your unit.

IMPORTANTExperience indicates that alcohoIblended fuels (catied gasohoI or usingethanol or methanoI) can attract mois-ture which leads to separation andformation of acids during storage. Acidicgas can damage the fuel system of anengine white in storage.To avoid engine problems, the fuel sys-tem should be emptied before storagefor 30 days or longer. Drain the gastank, start the engine and _etit run until

the fuel tines and carburetor are empty.Use fresh fuel next season. See STOR-AGE instructions for additional informa-tion.

Never use engine or carburetor clean-er products in the fuel tank or perma-nent damage may occur.See the STORAGE section for addition-al information.

mLWARNING: The chain must notmove when the engine runs at idlespeed, if the chain moves at idlespeed, refer to CARBURETOR ADJUST-MENTwithin this manual. Avoid con-tact with the muffler. A hot muffIer cancause serious burns.

STOPPING YOUR ENGINE• Move ON/STOP switch to STOP.STARTING YOUR ENGINETo start the engine, hoid the saw firmlyon the ground as illustrated. Makesure the chain is free to turn withoutcontacting any object.Important point8 to rememberWhen pulting the starter rope, do notuse the fut[ extent of the rope as thiscan cause the rope to break. Do notlet starter rope snap back. Hold thehandle and [et the rope rewind slowly.For cold weather starting, start the unitat FULL CHOKE; allow the engine towarm up before squeezing the throttletrigger. Do not cut material with thechoke/fast idle lever at the FULLCHOKE position.

If en-gine still fails to start, refer to theTROUBLESHOOTING CHART or call1-800-235-5878.

OPERATING TIPS• Check chain tension before first use

and after 1 minute of operation. SeeCHAIN TENSION in the MAINTENANCEsection.

• Cut wood only. Do not cut metal,plastics, masonry, non-wood buildingmaterials, etc.

• Stop the saw if the chain strikes aforeign object. Inspect the saw andrepair parts as necessary.

• Keep the chain out of dirt and sand.Even a small amount of dirt will

quickly dull a chain and increase thepossibility of kickback.

• Practice cutting a few small logs us-ing the following steps. This will helpyou get the '_feel" of using your sawbefore you begin a major sawing op-eration.• Squeeze the throttle trigger and al-

low the engine to reach fuIt speedbefore cutting.

• Begin cutting with the saw frameagainst the tog.

• Keep the engine at full speed theentire time you are cutting.

• Allow the chain to cut for you. Exertonly light downward pressure.

• Release the throttle trigger as soonas the cut is completed, allowingthe engine to idle. If you run thesaw at futt throttle without a cuttingload, unnecessary wear can occur.

• To avoid losing control when cut iscomplete, do not put pressure onsaw at end of cut.

• Stop engine before setting sawdown.

TREE FELLING TECHNIQUES

4HII,WARNING: Check for broken ordead branches which can fall while

cutting causing serious injury. Do notcut near buildings or electrical wires ifyou do not know the direction of treefall, nor cut at night since you wilt notbe able to see welt, nor during badweather such as rain, snow, or strongwinds, etc.• Carefully plan your sawing operation

in advance.• Clear the work area. You need a

clear area all around the tree so youcan have secure footing.

• Study the natural conditions that cancause the tree to fall in a particulardirection. These conditions include:

• The wind direction and speed.• The lean of the tree. The lean of a

tree might not be apparent due touneven or sloping terrain. Use aplumb or level to determine the di-rection of tree lean,

• Weight and branches on one side.• Surrounding trees and obstacles.

• Look for decay and rot. If the trunk isrotted, it can snap and fall toward theoperator.

• Make sure there is enough room forthe tree to fall. Maintain a distance of

2-1/2 tree lengths from the nearestperson or other objects. Enginenoise can drown out a warning call.

• Removedirt,stones,loosebark,nails,staples,andwirefromthetreewherecutsaretobemade.

FELLING LARGE TREES(6 inches in diameter or larger)The notch method is used to felI largetrees. A notch is cut on the side of thetree in the desired direction of fall. Aftera felling cut is made on the oppositeside of tree, the tree will tend to felt inthe direction of the notch.NOTE: if tree has targe buttress roots,remove them before making the notch.NOTCH CUT AND FELLING TREE• Make notch cut by cutting the top of

the notch first. Cut through t/3 of thediameter of the tree. Next completethe notch by cutting the bottom. Seeillustration. Once the notch is cut, re-move the wedge of wood from tree.

FinaI cut here

First cut _"_1

Notch

\ Hinge

• After removing the wood, make thefelling cut on the opposite side of thenotch. This is done by making a cutabout two inches higher than thecenter of the notch. This will leaveenough uncut wood between the fell-ing cut and the notch to form a hinge.This hinge wi_I hetp prevent the treefrom falling in the wrong direction.

Hinge holds tree onstump and helpscontrol fail

damage, use wood or plastic wedges,but never steeI or iron wedges.

• Be alert to signs that the tree isready to fall: cracking sounds, widen-ing of the felling cut, or movement inthe upper branches.

• As tree starts to fa}l, stop saw, put ftdown, and get away quickly on yourplanned retreat path.

• Be extremely cautious with partiallyfallen t_ees that may be poorly sup-ported. When e tree doesn't fall com-pletely, set the saw aside and puttdown the tree with a cable winch,bIock and tackle, or tractor Do not

use your saw to cut down a partiallyfatten tree.

CUTTING A FALLEN TREE(BUCKING)Bucking is the term used for cutting afallen tree to the desired tog size.

,_t, WARNING: Do not stand on the

log being cut. Any portion can rollcausing toss of footing and control. Donot stand downhill of the log being cut.

IMPORTANT POINTS• Cut onty one log at a time.• Cut shattered wood very carefully;

sharp pieces of wood could be flungtoward operator.

• Use a sawhorse to cut small logs.Never allow another person to holdthe log while cutting and never holdthe log with your leg or foot.

• Do not cut in an area where logs,limbs, and roots are tangled. Drag logsinto a clear area before cutting them.

BUCKING TECHNIQUES

_t, WARNING: If saw becomes

pinched or hung in a log, don't try toforce it out. You can lose control of thesaw _est_lting in in}ury a_d/or damageto the saw. Stop the saw, drive awedge of plastic or wood into the cutuntil the saw can be removed easily. Re-start saw and cs.refutly reenter the cut.Do not use a metal wedge. Do not at-tempt to restart your saw when it ispinched or hung in a log.

NOTE: Before felling cut is complete,use wedges to open the cut whennecessary to control the direction offall, To avoid kickback and chain

Turn saw OPF and use a plastic orwooden wedge to force cut open

Overcutting begins on the top side ofthe log with the bottom of the sawagainst the log. When overcutting uselight downward pressure.

Overcutting Undercutting

Undercutting involves cutting on theunderside of the log with top of sawagainst the tog. When undercuttinguse Iight upward pressure, Hold sawfirmly and maintain control The sawwilt tend to push back toward you.

_WARNING: Never turn saw up-side down to undercut. The saw can-not be controlled in this position,

Always make your first cut on thecompression side of the log.

LIMBING AND PRUNING

d_WARNING: Never climb into atree to limb or prune. Do not stand onladders, platforms, a log, or in any po-sition which can cause you to loseyour balance or controt of the saw.IMPORTANT POINTS• Watch out for springpoles.

Springpotes are small size limbswhich can whip toward you, or pultyou off balance. Use extreme cau-tion when cutting small size limbs.

• Be alert for springback. Watch out forbranches that are bent or underpressure. Avoid being struck by thebranch or the saw when the tensionin the wood fibers is released.

• Frequently clear branches out of theway to avoid tripping over them.

LIMBING• Limb a tree only after it is cut down.• Leave the larger limbs underneath the

felled tree to support the tree as youwork.

• Start at the base of the feIled tree and

work toward the top, cutting branchesand limbs. Remove small limbs withone cut.

10

• Keep the tree between you and thechain.

• Remove larger, supporting brancheswith the 1/3, 2/'3cutting techniques de-scribed in the bucking section.

• Always use an overcut to cut smalland freely hanging limbs. Undercuttingcould cause limbs to fall and pinch theSaW.

PRUNING

_iLWARNING: Limit pruning to limbs

shoulder height or below. Do not cut ifbranches are higher than your shoul-der. Get a professional to do the job.• Make your first cut t/3 of the way

CUSTOMER RESPONSIBILITIES

through the bottom of the limb.• Next make a second cut all the way

an improperly adjusted carburetor.Check these conditions before adjust-ing the carburetor.The carburetor has been carefully setat the factory. Adjustments may benecessary if you notice any of the fol-lowing conditions:• Chain moves at idle. See IDLE

SPEED-T under adjusting procedure.• Saw wJtt not idle. See iDLE SPEED-T

and LOW SPEED MIXTURE-L underadjusting procedure.

• Engine dies or hesitates when itshould accelerate. See ACCELERA-TION CHECK under adjustingprocedure.

• Loss of cutting power. See HIGHSPEED MIXTURE-H under adjustingprocedure.

There are three adjustment screws onthe carburetor. They are tabeted H, L,and T. They are located in the area justabove the primer bulb.CARBURETOR PRESETSWhen making adjustments, do notforce the plastic timiter caps beyondthe stops or damage will occur.If carburetor presets are not needed,proceed to iDLE SPEED-T.• Turn both mixture screws counter-

clockwise until they stop,• Turn the idle speed screw clockwise

until it stops. Now turn counterclock-wise 4-1/2 full turns.

Start motor, let it run for 3 minutes, andproceed to the adjustment section, ifengine does not start, refer to TROU-BLESHOOTING CHART or cat_1-800-235-5878.If engine performance is acceptable atthe preset positions and there is nochain movement at idle, no further ad-justment is necessary.ADJUSTING PROCEDUREIdle Speed-TAllow engine to idle. Adjust speed untilengine runs without chain movement

or stalling.• Turn clockwise to increase engine

speed if engine stalls or dies.• Turn counterclockwise to decrease

speed.No further adjustments are necessaryif chain does not move at idle speedand if performance is satisfactory.Low Speed Mixture-LAllow engine to idle. Then acceleratethe engine and note performance. Ifengine hesitates, bogs down, orsmokes during acceleration, turn mix-ture screw clockwise in 1/16-turn incre-ments until performance is satisfactory.Repeat this procedure as necessaryfor proper adjustment. After completingadjustments, check for accelerationand chain movement at idle. Reset if

necessary.High Speed Mixture-HDO NOT operate engine at full throttlefor prolonged periods while making ad-justments, Damage to the engine canoccur. Make a test cut. Based on per-formance of the saw while cutting, ad-just the high speed mixture setting in1/16-turn increments as follows:• Clockwise until saw has good power

in the cut with no hesitation. Do notadjust by sound or speed, but judgeby how well the saw performs in thecut.

• Counterclockwise if the saw hasspeed, but dies in the cut or lackspower in the cut.

After completing adjustments, checkfor acceleration and chain movementat idle. Reset if necessary.Acceleration CheckIf the engine dies or hesitates instead ofaccelerating, turn the low speed mixtureadjustment counterclockwise until youhave smooth acceleration with no chain

movement at idle. Recheck and adjustas necessary for acceptable perfor-mance.
