BEFORE STARTING ENGINEADD OIL

Your lawnmower is shipped without oil inthe engine. Engine holds 20 oz. of oil.For type and grade of oil to use, see"ENGINE" in Maintenance section of thismanual.1. Be sure lawnmower is level and area

around oil fig is clean.2. Remove engine oil cap and fill to the

full line on the dipstick. Pour oilslowly. Do not over fill.

NOTE: Allow oil to settle down intoengine for accurate reading. To readproper level, tighten engine oil cap, thenremove it to read the dipstick.3, Reinstall engine oil cap and tighten.• Check oil level before each use. Add

oil if needed. Fill to full line on dipstick.• 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 gaso-line. Purchase fuel in quantities thatcan be used within 30 days to assurefuel freshness.

_I_WARNING: Experience indicates thatalcohol blended fuels (called gasohol orusing ethanol or methanol) can attractmoisture which leads to separation andformation of acids dudng 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 gas tank, start theengine and let it run until the fuel linesand carburetor are empty. Use fresh fuelnext season. See Storage Instructions foradditional information. Never use engineor carburetor cleaner products in the fueltank or permanent damage may occur.

CAUTION: Fill to bottom of gas tankfiller neck. Do not overfill. Wipe off anyspilled oil or fuel. Do not store, spill orusa gasoline near an open flame.

TO START ENGINE

NOTE: Due to protective coatings on theengine, a small amount of smoke may bepresent during the initial use of theproduct and should be considerednormal.1. 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 afew minutes.

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

TO STOP ENGINE

• To stop engine, release operatorpresence control bar.

NOTE: In cooler weather it may benecessary to repeat priming steps. Inwarmer weather over pdming may causeflooding and engine will net start. If youdo flood engine, wait a few minutesbefore attempting to start and do notrepeat priming steps.

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 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 withuse 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 MOWINGTIPS

IMPORTANT: For best performance,keep mower housing free of built-upgrass and trash. See "Cleaning" inMAINTENANCE section of this manual.• The special mulching blade will recur

the 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.Always mulch with your highest engine(blade) speed as this will provide thebest recutting 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 by overlapping previouslycut path and mow slowly.

• Certain types of grass and grassconditions 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 pattern 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.
