ENGINE SPEED CONTROL

The engine speed was set at the factoryfor optimum performance. Speed is notadjustable.ENGINE ZONE CONTROL

A, CAUTION: Federal regulations requirean engine control to be installed on thislawn mower in order to minimize the risk

of blade contact injury. Do not under anycircumstances attempt to defeat thefunction of the operator control. The bladeturns when the engine is running.

• Your lawn mower is equipped with anoperator presence control bar whichrequires the operator to be positionedbehind the lawn mower handle to start and

operate the lawn mower.TO ADJUST cu'rrlNG HEIGHT

* Raise wheels for low cut and lower wheelsfor high cut.

• Adjust cutting height to suit your require-ments. Medium position is best for mostlawns.

• To change cutting height, squeeze adjusterlever toward wheel. Move wheel up ordown to suit your requirements. Be sure allwheels are in the same setting.

NOTE: Adjuster is properly positionedwhen plate tab inserts into hole in lever.Also, 9-position adjusters (if so equipped)allow lever to be positioned between theplate tabs.

BEFORE STARTING ENGINEOIL

Your lawn mower is shipped without oil in theengine.• Be sure mower is level and area around oil

fill is clean.

• Remove engine oilcap and fillto the fullline on the dipstick.

NOTE: Allow oil to settle down into

engine for accurate dipstick reading.

• Engine holds 20 ozs. of oil. For type andgrade of oil to use, see "ENGINE" inMaintenance section of this manual.

• Pour oilslowly. Do not over fill.• Check oil level before each use. Add oil if

needed. Fill to full line on dipstick.• To read proper level, tighten engine oil cap

each time.• Reinstall engine oil cap and tighten.• Change the oil after every 25 hours of

operation or each season. You may needto change the oil more often under dusty,dirty conditions.

ADD GASOLINE MOWING TIPS• Fill fuel tank. Use fresh, clean, regular •

unleaded gasoline with a minimum of87 octane. Do not mix oil with gasoline.Purchase fuel in quantities that can beused within 30 days to assure fuelfreshness.

A, WARNING: Experience indicates thatalcohol blended fuels (called gasohol orusing ethanol or methanol) can attractmoisture which leads to separation and •formation of acids during storage. Acidicgas can damage the fuel system of anengine while in storage. To avoid engine •problems, the fuel system should beemptied before storage of 30 days orlonger. Drain the fuel tank, start the •engine and let it run until fuel lines andcarburetor are empty. Use fresh fuel nextseason. See Storage Instructions foradditional information. Never use engineor carburetor cleaner products in fuel tankor permanent damage may occur.

ACAUTION" Fill to bottom of gas tankfiller neck. Do not overfill. Wipe off any •spilled oil or fuel. Do not store, spill or usegasoline near an open flame.

TO START ENGINE• To start a cold engine, push primer

three (3) times before trying to start.Use a firm push. This step is notusually necessary when starting anengine which has already run for a fewminutes.

• Hold operator presence control bardown to the handle and pull starterhandle quickly. Do not allow starterrope to snap back.

• To stop engine, release operatorpresence control bar.

NOTE: In cooler weather it may benecessary to repeat priming steps. Inwarmer weather over priming may causeflooding and engine will not start. If youdo flood engine, wait a few minutesbefore attempting to start and do notrepeat priming steps.Engine oil cap Gasoline filler

cap

Under certain conditions, such as verytall grass, it may be necessary to raisethe height of cut to reduce pushingeffort and to keep from overloading theengine and leaving clumps of grassclippings. It may also be necessary toreduce ground speed and/or run thelawn mower over the area a secondtime.

For extremely heavy cutting, reduce thewidth of cut by overlapping previouslycut path and mow slowly.For better grass bagging and mostcutting conditions, the engine speedshould be set in the fast position.For side discharge lawn mowers,cutting in a counter-clockwise direction,starting at the outside of the area to becut, spreads grass clippings moreevenly and puts less load on theengine. To keep clippings off ofwalkways, flower beds, etc., make thefirst cuts in a clockwise direction.Pores in cloth grass catchers canbecome filled with dirt and dust with

use and catchers will collect less grass.To prevent this, regularly hose catcheroff with water and let dry before using.Keep top of engine around starter clearand clean of grass clippings and chaff.This will help engine air flow andextend engine life.

MULCHING MOWING TIPS

IMPORTANT: For best performance, keepmower housing free of built-upgrass andtrash. See "Cleaning" in MAINTENANCEsection of this manual.

• The special mulching blade will recut thegrass clippings many times and reducethem in size so that as they fall onto thelawn they will disperse into the grass andnot be noticed. Also, the mulched grasswill biodegrade quickly to provide nutrientsfor the lawn. Always mulch with yourhighest engine (blade) speed as this willprovide the best recutting action of theblades.

• Avoid cutting your lawn when it is wet. Wetgrass tends to form clumps and interfereswith the mulching action. The best time tomow your lawn is the early aftemoon. Atthis time the grass has dried and the newlycut area will not be exposed to the directsun.

• For best results, adjust the lawn mower

cutting height so that the lawn mower cuts

off only the top one-third of the grassblades. If the lawn is overgrown it will benecessary to raise the height of cut toreduce pushing effort and to keep fromoverloading the engine and leavingclumps of mulched grass. For extremelyheavy mulching, reduce your width of cutby overlapping previously cut path andmow slowly.Certain types of grass and grass condi-tions may require that an area be mulcheda second time to completely hide theclippings. When doing a second cut, mowacross or perpendicular to the first cut path.Change your cutting pattem from week toweek. Mow north to south one week thenchange to east to west the next week. Thiswill help prevent matting and graining ofthe lawn.

TO SHARPEN BLADE

NOTE: We do not recommend

sharpening blade - but if you do, be surethe blade is balanced.

Key.,Lockwasher

Care should be taken to keep the bladebalanced. An unbalanced blade willcause eventual damage to lawn mower orengine.• The blade can be sharpened with a file

or on a grinding wheel. Do not attemptto sharpen while on the mower.

• To check blade balance, drive a nailinto a beam or wall. Leave about oneinch of the straight nail exposed. Placecenter hole of blade over the head ofthe nail. If blade is balanced, it shouldremain in a horizontal position. If eitherend of the blade moves downward,sharpen the heavy end until the bladeis balanced.

ENGINEFUEL SYSTEM

IMPORTANT: It is importantto prevent gumdeposits from forming in essential fuel systemparts such as carburetor, fuel filter, fuel hose,or tank during storage. Also, experienceindicates that alcohol blended fuels (calledgasohol or using ethanol or methanol) canattract moisture which leads to separationand formation of acids during storage. Acidicgas can damage the fuel system of anengine while in storage.• Drain the fuel tank.

• Start the engine and let it run until the fuellines and carburetor are empty.

• Never use engine or carburetor cleanerproducts in the fuel tank or permanentdamage may occur,

• Use fresh fuel next season.

NOTE: Fuel stabilizer is an acceptablealternative in minimizing the formation of fuelgum deposits during storage. Add stabilizerto gasoline in fuel tank or storage container.Always follow the mix ratio found on stabilizercontainer. Run engine at least 10 minutesafter adding stabilizer to allow the stabilizer toreach the carburetor. Do not drain the gastank and carburetor if using fuel stabilizer.ENGINEOIL

Drain oil (with engine warm) and replace withclean engine oil. (See "ENGINE" in theMaintenance section of this manual).CYLINDER• Remove spark plug.• Pour one ounce (29 ml) of oil through

spark plug hole into cylinder.• Pull starter handle slowly a few times to

distribute oil.

• Replace with new spark plug.

14

OTHER

• Do not store gasoline from one season toanother.

• Replace your gasoline can if your canstartsto rust. Rust and/or dirtin yourgasoline will cause problems.

• If possible, store your unit indoors andcover it to give protectionfrom dust and dirt.

• Cover your unit with a suitable protectivecover that does not retain moisture. Do not

use plastic. Plastic cannot breathe whichallows condensation to form and will cause

your unit to rust.TROUBLESHOOTING CHART
