BEFORE STARTING ENGINEOIL

Your lawn mower is shipped without oil inthe engine.• Be sure mower is level and area

around oil fill is clean.

• Remove engine oil cap and fill to theupper limit mark on dipstick.

NOTE: Allow oil to settle down into

engine for accurate dipstick reading.• Engine holds 18 112 ozs. of oil. For

type and grade of oil to use, see=ENGINE" in Maintenance section ofthis manual.

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

oil if needed. Fill to the upper limit markon dipstick.

• To read proper level, insert the dipstickinto the tube and rest engine oil cap onthe tube. Do not thread the cap ontothe tube. Remove and read the oillevel.

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

operation or each season. You mayneed to change the oil more oftenunder dusty, dirty conditions.

ADD GASOLINE

• Fill fuel tank. Use fresh, clean, regularunleaded 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.

AWARNING: Experience indicates thatalcohol blended fuels (called gasohol orusing ethanol or methanol) can attractmoisture which leads to separation andformation of acids during storage. Acidicgas can damage the fuel system of anengine while in storage. To avoid engineproblems, the fuel system should beemptied before storage of 30 days orlonger. Drain the fuel tank, start theengine 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._IICAUTION: Fill to bottom of gas tankfiller neck. Do not overfill. Wipe off anyspilled oil or fuel. Do not store, spill or usegasoline near an open flame.

TO START ENGINE MULCHING MOWING TIPS

• Turn fuel valve to ON position.• To start a cold engine, move handle

mounted throttle/choke control lever tochoke position.

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

• Slowly move throttle control lever tofast position after engine starts.

• To start a warm engine, move throttlecontrol lever to fast or slow positionthen follow steps above.

• To stop engine, release operatorpresence control bar. Wait until bladeand all moving parts have stopped andtum fuel valve to OFF position if you donot intend to restart the engine soon.

IMPORTANT: For best performance, keepmower housing free of built-up grass andtrash. Clean UNDERSIDE OF MOWER

HOUSING after each use. See "Cleaning"in MAINTENANCE section of this manual.

• The special mulching blade will recutthe grass clippings many times andreduce them in size so that as they fallonto the lawn they will disperse into thegrass and not be noticed. Also, themulched grass will biodegrade quicklyto provide nutrients for the lawn. Alwaysmulch with your highest engine (blade)speed as this will provide the bestrecutting action of the blades.

• Avoid cutting your lawn when it is wet.Wet grass tends to form clumps andinterferes with the mulching action. Thebest time to mow your lawn is the earlyafternoon. At this time the grass hasdried and the newly cut area will not beexposed to the direct sun.

• For best results, adjust the lawn mowercutting height so that the lawn mowercuts off only the top one-third of thegrass blades. If the lawn is overgrown itwill be necessary to raise the height ofcut to reduce pushing effort and to keepfrom overloading the engine andleaving clumps of mulched grass. Forextremely heavy mulching, reduce yourwidth of cut, mow slowly and raisethe rear of the lawn mower one wheel

adjuster setting higher than the front.• Certain types of grass and grass

conditions may require that an area bemulched a second time to completelyhide the clippings. When doing asecond cut, mow across or perpendicu-lar to the first cut path.

• Change your cutting pattem from weekto week. Mow north to south one weekthen change to east to west the nextweek. This will help prevent mattingand graining of the lawn.

On

Fuel Valve lever

MOWINGTIPS

• 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 ovedapping previouslycut path and mow slowly.

• For better grass bagging and mostcutting conditions, the engine speedshould be set in the fast position.

• Pores in cloth grass catchers canbecome filled with dirt and dust with use

and catchers will collect less grass. Toprevent this, regularly hose catcher offwith 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. 9

TO SHARPEN BLADE

NOTE: We do not recommend

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

Care should be taken to keep the bladebalanced. An unbalanced blade will

cause 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 one

inch 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.
