FUEL RECOMMENDATIONS

Useclean,freshunleaded gasoline havinga mini-mum octanerating (Anti-KnockIndex) of 87.

Duringsometimes oftheyear only mandated oxy-genated gasolines may be available. These areacceptable for use, but not preferable. Leaded gas-oline may beused but willresult inthe extra mainte-nancerequired for removingcombustionchamberand spark plug deposits. Do not use gasoline orgasoline additives (de-icers) containing methanolbecause methanolcanbecorrosiveto fuelsystemcomponents.

Do not use gasoline or gasolinead-ditives containing methanolbecause methanolcanbecorrosiveto fuelsystemcomponents.

Avoidusing highly leaded gasolines and leadadditives because ofthe extraengine mainte-nancethat willberequired.

Gasoline is highly flammable andcancausesevere personal injury or death.Donot smoke ifyou smell gasoline or are near fueltanks or gasoline-burning equipment or are inan area sharing ventilation with such equip-ment.Keep flames,sparks,pilot lights,electri-cal arcs and arc-producing equipment and all

other sources of ignitionwellaway.

ENGINE OIL RECOMMENDATIONS

Use premium quality motor oil. Look for the API(American Petroleum Institute) classification anduseClass SGor SHoil (alsoSG/CD, SG/CE, SH/CD or SH/CE). Also look for the SAE (Society of Au-tomotive Engineers)viscosity grade. Referring toTable 1, choosetheviscosity gradeappropriate fortheambient temperatures expected duringthe peri-od oftimeuntilthe next scheduled oilchange.

Single-grade SAE30 oil is preferablewhentemper-atures areconsistently above freezing.Multigradeoils are better whenwide temperature variationsare expected.

STARTING BATTERIES

The engine is equippedwith a 12 volt electricstart-er. Prompt starting requires sufficient battery ca-pacity and battery cablesize. Neither cranking per-formance nor starter service lifewill besatisfactory

withanundersizedbattery.

Regular,monthly maintenance ofbatteries may berequired. See Periodic Maintenance and anyinstructions available fromthe equipment or batterymanufacturer. It should be notedthat as long as theequipment is operatedregularly,the automatic bat-tery recharging system on the engine should beable to maintain battery charge. See OUT-OF-SERVICE PROTECTIONunder Operationregard-ingbattery care duringstorage for prolonged peri-ods.

EXHAUST SYSTEM

EXHAUST GAS IS DEADLY! Mobile engine-pow-ered equipment must never be operated insidebuildings or other enclosedspaces without amplefreshair ventilation.

Stationary engine-powered equipment installed in-side buildings or other enclosedspaces must beequippedwith a leak-free exhaust systemthat car-ries all exhaust gases tothe outside,well away fromallwindows, doors,vents and other openings into

thebuilding or enclosure.It is theresponsibility ofthe equipment operator(s)tocheck for exhaust leaks ona daily basis andtohaveall leaks repaired before continuingto operatethe equipment.

ENGINE BREAK-IN

Engine break-in as aresult of proper care duringthefirst hours of operation of a new or rebuilt enginere-sults inthe ideal fitting ofall internal moving metal

parts, which is essential for top engine perfor-mance.For controlled enginebreak-in:

1. Operatethe equipment as it is intendedtobeoperated.However, for the first 3 hours, if pos-sible,operatethe equipment at about halftheavailable engine power, occasionally operatingat full engine power for brief periods. Also, ifpossible, avoid prolonged low-speed, low-power operation during enginebreak-in.

2. Proper engine oil is especially critical during

break-inbecause ofthe higher enginetemper-atures that can be expected. See REC-OMMENDED ENGINE OIL in Introduction.Changethe oil if it is not appropriate for the am-bient temperatures duringthebreak-in period.SeeTable 1.

3. Checkthe oil leveltwicea day or after every 4hours of operation duringthe first 24 hours ofoperation.

4. Change the oil and oil filter after the first 24hours of operation.

OPERATION IN DUSTY CONDITIONS

1. Keepthe engine cooling fins and flywheel airinlet screenclean.

2. Perform air cleaner maintenance more oftenthan normalas required.SeeTable2.

3. Changethe engine oil and oil filter more oftenthan normal.SeeTable2.

OPERATION IN HOT WEATHER

Pay particular attentiontothe following items whenoperatingthe engine intemperatures above 100 F(38 C):

1. Keepthe flywheelair inlet screenandcylindercooling fins clean. See to it that nothing ob-structs air flow toand fromthe engine.

2. Checkthe oil level more frequently.

3. Changethe oil and oil filter more oftenthan nor-mal.SeeTable2.

4. Makesurethe engine oilviscosity is appropri-ate for theambient temperatures andchangethe oil if necessary.SeeTable 1.

OPERATION IN COLD WEATHER

OUT-OF-SERVICE PROTECTION

Protect an enginethat will be out ofservice for morethan30 days as follows:

1. Runthe engineuntil it reaches normal operat-

ingtemperature,shut offthe fuelsupply and letthe enginerununtil it stops.Also,ifthe equip-ment will not be operated for more than 120days, adda fuel preservative (OnaFreshTM)tothe equipment fueltank. Follow the instructionsonthe container label. Unless a preservative(stabilizer) is added,the gasolinewill deterio-ratecausing fuelsystem corrosion, gum forma-tion andvarnish-like deposits which can leadtohardstartingandrough operation.

Gasoline preservatives (stabi-lizers)aretoxic.Follow the instructions on

the container label. Avoid skin contact.Washyour hands withsoapandwater afterdispensingthe fluid.

2. Drain the oil from the engine while it is stillwarm.Refillwith fresh oil and attach atagstat-ingtheviscosity ofthe oilused.

3. Remove thespark plugs and squirt 1 ounce(2 tablespoons or 28 grams) ofrust inhibitor orSAE30 oil into each cylinder. Crankthe engineover afew times andreinstallthespark plugs.

4. Performair cleaner maintenance as instructed

in Periodic Maintenance.5. Cleanthe governor linkageandwrap it witha

cleancloth for protection.

6. Plug the exhaust outlet to prevent moisture,dirt, bugs,etc. from entering.

7. Provideasuitablecover for the entireunit.

8. Ifso equipped, disconnect the battery (nega-tive [] cable first) and follow the battery orequipment manufacturers storage instruc-tions.

RETURNING THE ENGINE TO SERVICE

1. Removethecover andall protectivewrappingandthe plug fromthe exhaust outlet.

2. Checkthetag onthe oil base. Changethe oil iftheviscosity is not appropriate for the expectedambient temperatures.SeeTable 1.

3. Checkthe fuel filter and fuel lines to makesure

they aresecureand have nocracks or leaks.

4. Checktoseethat the choke,throttle and gover-nor linkages move freely.

5. Ifso equipped, clean and checkthe battery ac-cordingtothebattery or equipment manufac-turers instructions and connect the batterycables (positive[+] cable first).

6. Start the engine. The initialstartup may beslowandthere may besmokeandrough operationfor a few minutes until the oil in the cylinderburns off.Ifthe engine does not start, clean orreplacethespark plugs as they may have beenfouled by the oil addedtothe cylinder whentheequipment was stored.

ENGINE SPEED ADJUSTMENT

Normally there is no needtoadjust enginespeed.These instructions are for the equipment manufac-turer insettingupandadjustingthe equipment.

Enginespeed adjustment must beattempted onlyby aqualified mechanic andtheadjustments mustbe made using an accurate tachometer. Set thelow-idle and high-idlespeeds tothevalues speci-fied inthe equipment Operators Manual. Inthe ab-sence ofsuchspecifications it is recommendedthatlow-idlespeed be adjustedto 1,100 RPM and high-idlespeedto3,400 RPM.

Adjustingthe enginespeedtoaval-ue above that specified by the equipmentmanufacturecouldcausethe equipment to op-

erateat speeds inviolation ofFederalandStateStandards for Safety for the equipment.

Moving parts cancausesevere per-sonal injury or death.Takecarewhen measur-ing enginespeedwithatachometer and followthe meter instructions.You must beaqualifiedmechanic.

ReferringtoFigure6, adjust the low-idleand high-idle enginespeeds as follows:

1. Start the engine, observing all ofthe equipment

manufacturers instructions and precautions.2. If the throttle cable has already been con-

nected, loosen the clamp at the engine andback out the low-idlespeedstopscrew sothatthe speed stop screw on the carburetortouches its stop. Adjust engine speed to1,000 RPM with the carburetor speed stopscrew.

3. Turn the low-idlespeedstopscrew to obtainthespecified low-idlespeed.

4. Movethe enginethrottle linkup against its stoptang and hold it therewhile bendingthetang as

necessary to obtain the specified high-idlespeed.

5. Hook the engine throttle linkwith the throttlecable, pulltheslack out ofthethrottle cable andtightenthe clamp. Check for full,smooth move-ment ofthe enginethrottle link between its twostop positions whenthe equipment throttle le-ver is movedthrough its fullrange.
