SAFETY PRECAUTIONSSafety is built into every engine driven generator; however, like any other electro-mechanical device it can present serious threat to life and
limb if imprudently operated and maintained, Remember that the best safeguards against accidents are to keep ever mindful of the potentialdangers and to always use good common sense. In the interest of safety, some general precautions are presented below - keep these in mind!
WARNING - HIGH VOLT AGE! Remember that the function of a generator set is to produce electricity and wherever electrical energy ispresent, there is the potential danger of electrocution. Keep everyone, especially children, away from the set while it is running and take precautions to prevent unqualified personnel from tampering with or attempting to operate your generator set. Have the set and electrical circuitsserviced only by qualified technicians and make sure that the battery is disconnected before any service is performed to prevent unintentionalstarting. Wiring should be inspected frequently - replace leads that are frayed or in poor condition. Be especially careful not to come in contactwith electrical equipment when standing in water or on wet ground or when your hands are wet.
WARNING - LETHAL EXHAUST GAS! The engine powering your generator discharges deadly carbon monoxide as part of the exhaust• gas when operating. Carbon monoxide is particularly dangerous in that it is odorless but keep in mind that it can cause death if inhaled for even
a short period of time. Never operate the generator set inside a building unless the exhaust gas is piped safely outside or operate in any areawhere exhaust gas could accumulate and seep back inside an occupied building. Keep exhaust system tight and in good condition at all times toprevent leakage. Avoid breathing exhaust fumes when working on or near the generator set.
WARNING - DANGEROUS FUELS! Use extreme caution when handling, storing and using fuels - they are highly volatile and explosivein vapor state. Store gasoline only in approved red containers clearly marked GASOLINE - store in well-ventilated area out of the reach ofchildren and away from any flame or spark producing equipment. Don't store gasoline inside home or any occupied building. Never add fuel totank while engine is running to prevent spilled fuel from igniting on contact with hot parts or from ignition spark. With gaseous fuel, make surethe system meets all safety codes and have it serviced only by qualified technicians.
WARNING - MOVING, HOT PARTS! Imprudent operation creates hazards to life and limb - never operate with safety guards removed,keep hands, feet, clothing away from moving and hot parts. Remember that an engine gets hot while running, and exhaust system componentsget extremely hot. Know how to make emergency stops - don't allow inexperienced persons to operate your set. Always disconnect battery or remove spark plug while working on equipment. Never tamper with governor setting to gain more power - the governor establishes safe operating limits. Overspeed not only shortens engine life but can be extremely hazardous.WARNING - GENERAL PRECAUTIONS! Handle starting batteries carefully - they are filled with acid which can eat thru clothing, bumskin, and cause blindness. Keep in mind that a battery gives off highly flammable hydrogen gas while being charged - charge only in well venti~lated area. While electrical energy produced in an engine ignition system may not be strong enough to cause injury, reaction to shock producedcould cause you to pull away and into contact with hot or moving parts - keep away from ignition system while operating. Never operate without adequate muffler or with faulty exhaust system - exposure to excessive noise is not only tiring but can lead to impairment of hearing.

OPERATING INSTRUCTIONS
PRE - START INSTRUCTIONSBefore each start, open the compartment and make the following checks:
OIL LEVEL: Must be in safe range.AIR INLETS: Must be clear.COMPARTMENT: Keep interior clean.
AIR CLEANER: Must be properly installed.FUEL FILTER: Service if needed.~ Make sure supply is adequate.
STARTING - STOPPING PROCEDUREThe START-STOP switches inside the motor home and on the controller are momentary contact
switches which means that they must be held in the STAR T position until the set starts running orwhen stopping, held in the STOP position until the unit comes to a complete halt. Whenever possible,allow a brief cooling period by running the unit at low or no load for a few moments just prior to shutdown.
PREVENTIVE MAINTENANCEIn addition to the routine services listed in this manual, there are other important steps that
should be taken to keep 3. generator set in top condition. Usually, tools and instruments required forthese additioClal steps are not available to the generator set owner. For this reason, the set should bereturned periodically to an authorized Service Center for complete servicing and tune-up. The benefitsof such service will not only be noted immediately in improved performance, but, most important, incontinued satisfactory operation during a long, trouble free service life.

CARBURETOR ADJUSTMENT
-I
Lack of power and black sooty exhaust smoke usually indicates that fuel mixture is too rich. An"overrich" mixture may also be caused by a clogged air cleaner--check this before readjusting carburetcH. Fuel mixture nlay be too lean if engine "skips" or backfires. Note that an overrich conditioncou1d a1so be caused by an inlproperly adjusted choke.
Main Fuel Adjustment: For preliminary setting, turn MAIN FUEL screw in clockwise direction until itbottoms lightly (do not force) then back out Z turns. With engine thoroughly warmed up and running at1800 RPM· and full load; turn MAIN FUEL screw in until engine slows down (lean setting) then turnscrew out until engine regains speed and then starts to slow down (overrich setting). Turn screw backin until it is positioned halfway between lean and overrich settings--when properly adjusted, enginewill operate with steady governor action.
Idle Adjustrnent: On generator set app1ications, the idle systenl functions only as the engine UHnes upthru idle range to 1800 RPM. For this reason, idle system has o'11y a mo~entary effect. To adjust.stop engine then turn IDLE FUEL screw all the way in (clockwise) until it bottoms lightly (do not forcescrew), then back out 1-1/4 turns--no further adjustment is needed.

FIGURE 5 - CARBURETOR ADJUSTMENTS FIGURE 6 - AUTOMATIC CHOKE ADJUSTMENT
AUTOMATIC CHOKEChokes are set at the factory but may have to be readjusted to suit local conditions. Remove air
cleaner from carburetor to observe position of choke plate. Choke adjustment must be made on coldengine. If starting in extreme cold, choke should be in full closed position before engine is started. Alesser degree of choking may be needed in milder temperatures. If adjustment is required, proceed asfollows: .
1. Move choke arm until hole in cross shaft lines up with slot in bearings.Z. Insert #43 drill (.089) thru hole and push all the way down to engine manifold to engage in
notch in base of choke unit (see accompanying figure).3. Loosen clamp bolt on choke lever, push arm upwardto move choke plate toward closed
position for increased choke or away to decrease choking effect. When properly positioned,tighten clamp bolt then remove drill.
4. After replacing air cleaner, check for evidence of binding in linkage--correct if necessary.Be sure choke is fully open when engine is at normal operating temperatures.
5
GOVERNOR ADJUSTMENTThe governor functions to maintain engine speed under changing load conditions and also acts as
a speed limiting device. Governor is set in the factory and further adjustment should not be requiredunless linkage works loose or becomes disconnected. Readjustment should be made if engine surgeswith changing load or if speed drops considerably when a normal load is applied.
Initial Adjustment: With engine stopped, loosen (do not remove) hex. nut securing governor arm togovernor cross shaft. Grasp end of cross shaft with pliers and turn shaft as far as possible in counterclockwise direction--tab on shaft will stop internally against governor gear mechanism. Hold shaft inthis position, pull governor arm all the way away from carburetor then retighten governor arm nut tocomplete initial adjustment.
Speed Adjustment: This set must be operated at 1800 RPM. If frequency or overspeed condition issuspected, check RPM with hand tachometer and readjust as follows: With constant speed arrangement,loosen speed adjusting nut to decrease speed or tighten to increase speed.

Sensitivity Adjustment: If speed drops considerably when a normal load is applied, governor should beset for greater sensitivity. If set too sensitive, speed surging will occur with changing load. Governorsensitivity is adjusted by repositioning governor spring in holes provided on arm and speed controlbrackets. Increase tension on spring (and sensitivity) by moving spring hooks into holes spaced furtherapart--conversely, decrease sensitivity by reducing tension on spring. Recheck engine speed andreadjust as needed after changing sensitivity.
COOLING SYSTEMKohler Air- Vac cooling is used on this set. With this system, cooling air is drawn into the genera
tor set compartment, circulated from the generator end, around the cooling fins and finally ejected asheated air downward thru the Air- Vac scroll at the flywheel end of engine. High-temperature cutout oncylinder head will stop the generator set if overheating occurs. Keep intake louvers, generator coolingopenings, cooling fins and scroll work clean and unobstructed at all tiDIes to prevent overheating--do notoperate with blower housing, scroll or cooling shrouds removed as this will also cause overheating.

FIGURE 9 -- BREAKER POINT GAP
Spark Plug: Every 100 hours remove plug and check condition. Good operating conditions are indicated1£ plug has light coating of gray or tan deposit. A dead white, blistered coating could indicate overheating. A black (carbon) coating may indicate an "overrich" fuel mixture caused by clogged air cleaner orimproper carburetor adjustment. Do not sandblast, wire brush, scrape or otherwise service plug inpoor condition--best results are obtained with new plug. Set standard and resistor type spark plug gapat .025". Tighten plug to 22 ft. lbs. torque when installing. Use 14 mm resistor type XH10 plug forsuppression of radio noise.
Breaker Points: Every 200 hours breaker points should be inspected and serviced. If oxidized, dirtyor oily, clean with coarse cloth--do not use emery cloth or- sandpaper. Slightly pitted points can bedressed with point file--replace badly pitted or burned points. The gap must be adjusted after pointsare serviced or replaced since this setting establishes ignition timing. To adjust, turn engine over byhand until points are at maximum opening--check with feeler gauge. If gap is not. 020", loosen adjusting screw then shift movable plate until. 020" gap is obtained. After retightening screw, recheck tomake sure gap is still properly set. ---
TROUBLE SHOOTING - ENGINEIf trouble occurs, don't overlook causes that seem too obvious to be considered such as an empty
fuel tank--check for the simplest causes first. To operate, an engine must have fuel, a good ignitionspark and, of course, good compression--keep this in mind when trying to pinpoint the cause.

GENERATOR SERVICEGenerators do not normally require service on a regular basis; however, it is a good idea to
remove the end cover and check the commutator and brushes at least every six months or every 50hours or more often under dusty, dirty conditions. Make a visual check of the commutator first--if athin skinlike film of uniform thickness is evident on the surface, this usually indicates normal operation--this film acts as a lubricant and promotes longer brush life. If the surface is streaked or has ridgesof dirt, clean it with a coarse cloth or, if this doesn't work, use fine sandpaper or a commutator stone-do not use emery cloth. Lift brushes and check surface--replace brush if unevenly worn or when worn~to about 1/2". Use genuine Kohler replacement brushes only--substitutes may not be of correctmaterial and will wear out rapidly or cause commutator damage. Other common causes for rapid brushwear are wrong brush tension, rough commutator surface, high mica on commutator and brush chatter.Blow dust out with i!.l. compressed air after servicing generator.
TROUBLE SHOOTING-GENERATORSome common causes of possible generating problems that can be detected and corrected without
test instruments are listed below. If routine service or the suggested corrective action fails to solvethe particular problem, contact a qualified electrical technician to remedy the malfunction. The information on Controller Operation provided on pages 8 and 9 is furnished to help the technician pinpointcauses of generator and controller problems.
PROBLEMPOSSIBLE CAUSE
NO OUTPUT
• LOOSE TERMINAL CONNECTIONS:Check for loose or bad connections--clean and tightenas needed. • BATTERY LEADS REVE RSED:
Make sure negative terminal is grounded.• BRUSHES NOT SEATED:
Check for loose springs or brushes sticking in holders.Correct condition. • DIRTY COMMUTATOR:
Poor brush contact caused by build up of dirt or oily film oncommutator--clean with coarse cloth or fine stone or sandpaper.• SHORT IN AC CI RCUIT:
If engine labors while running or jerks while being cranked,check for short circuit in AC line.• OPEN GENERATOR FIELD:
Have technician check for this condition.
LOW OUTPUT OR
• ENGINE SPEED TOO LOW:Check speed with tachometer--load speed should be 1800 RPM
EXCESSI VE DROP
(full load).Readjust governor speed and sensitivity as required.IN VOLTAGE
• OVERLOAD:If all possible electrical loads are on at the same time, overload
condition may exist--turn off unnecessary loads .• ENGINE IN POOR CONDITION: Faulty ignition, excessive carbon, poor compression,clogged air cleaner or any other condition ~ausing poor performance of the enginemay show up in reduced output.
Repair or service engine as needed.
CONTROLLERThe controller, which is the unit on top of the generator, controls the set thru all phases of
operation. The set may be started and stopped at the switch on the controller or the switch inside themotor horne. Refer to the controller illustration on page 14 for parts identification and to the wiringdiagram on the opposite page to trace the sequence of operation as explained in the following.
1.
2.
SWITCH IN STAR T POSITION: This completes the starting circuit allowing battery current to flowfrom the positive terminal thru cranking contactor C and back to battery negative terminal. Thiscurrent magnetically draws contacts of C closed which allows heavy battery current to flow thruthe cranking series windings and the exciter armature thus motoring the engine for starting. Theinitial current also activates the choke coil. The switch must be released to open the crankingcircuit immediately after the engine starts.
SWITCH I~ R UN (CENTER) POSITION: Switch returns to run position when released. Enginequickly comes up to speed and power is furnished from the generator collector rings thru terminalsLl and L2. As exciter voltage rises, lCR and 2CR relay coils energize. Contacts of lCR connect the battery charging circuit to the battery. Contacts of 2CR allow the battery charging relay(regulator relay) RR to sense battery voltage which varies the charge rate from 1 to 6 amps byopening or closing the circuit thru resistor lR2.
.--
3. SWITCH IN STOP POSITION: This grounds out the magneto ignition system at terminal 5 to stopthe engine- -the switch must be held in the stop position until the engine comes to a complete halt-if released too soon the engine may restart.

STORAGE INSTRUCTIONSIf your generator set is to be out of service for a considerable length of time, the following steps
should be taken to preserve the set before placing it in storage.
STEP 1: Drain oil from crankcase (while hot) then flush with clean light weight oil. Refill crankcasewith regular weight oil after flushing with the light oil.
STEP 2: Drain fuel from filter sediment bowl, carburetor bowl, and fuel tank. This is done to prevent the gasoline from becoming "stale" which results in formation of gum.
STEP 3: Remove the spark plug, pour about 1 tablespoon of oil into the hole, crank the engine severaltimes then reinstall the spark plug.
STEP 4: Clean exterior surfaces of generator set then spread a light film of oil over any unpaintedmetallic surfaces which could corrode.
STEP 5: Place dust cover over the generator set and store in cool, dry space.
