OIL

Yourlawnmower is shippedwithoutoil in the engine.

• Be sure mower is level and area around

oil fill is clean.

• Remove engine oil cap w/dipstick and fill

to the full line on the dipstick.

• Use 20 ozs. of oil. For type and grade of oil to use, see "ENGINE" in Maintenance

section of this manual.

• Pour oil slowly. 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 need

to change the oil more often under dusty, dirty conditions.

GAS

• Fill fuel tank. Use fresh, clean, regular unleaded gasoline with a minimum of 87 octane. Do not mix oil with gasoline. Pur-

chase fuel in quantities that can be used within 30 days to assure fuel freshness.

WARNING: Experience indicates that alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an en- gine while in storage. To avoid engine

problems, the fuel system should be emp- tied before storage of 30 days or longer.

Drain the fuel tank, start the engine and let

it run until fuel lines and carburetor are empty. Use fresh fuel next season.

See

Storage Instructions for additional information. Never use engine or carburetor cleaner products in fuel tank or permanent damage may occur.

TO START ENGINE

• To start a cold engine, push primer five

(5) times before trying to start. Use a firm push. This step is not usually necessary

when starting an engine which has

already run for a few minutes.

• Hold operator presence control bar down

to the handle and pull starter handle quickly. Do not allow starter rope to snap back.

• To stop engine, release operator presence control bar.

NOTE: In cooler weather it may be neces-

sary to repeat priming steps. In warmer

weather over priming may cause flooding and engine will not starL If you do flood engine, wait a few minutes before attempting to start and do not repeat priming steps.

MOWING TIPS

•

Under certain conditions, such as very tail

grass, it may be necessary to raise the

height of cut to reduce pushing effort and

to keep from overloading the engine and leaving clumps of grass clippings.it may also be necessary to reduce ground speed and/or run the lawn mower over the area a second time.

•

•

•

•

For extremely heavy cutting, reduce the width of cut by overlapping previously cut

path and mow slowly.

For better grass bagging and most cutting

conditions, the engine speed should 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 be cut, spreads grass clippings more evenly and

puts less load on the engine. To keep clip-

pings off of walkways, flower beds, etc., make the first cuts in a clockwise direction.

Pores in cloth grass catchers can become filled with dirt and dust with use and catchers will collect less grass. To prevent

this, regularly hose catchers off with water and let dry before using.

Keep top of engine around starter clear

and clean of grass clippings and chaff.

This will help engine air flow and extend engine life.

MULCHINGMOWINGTIPS mowerhousingfree of built-upgrass

and trash. Clean UNDERSIDE OF MOWER

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

• The special mulching blade will recut the

grass clippings many times and reduce them in size so that as they fall onto the lawn they will disperse into the grass and

not be noticed. Also, the mulched grass will biodegrade quickly to provide nutrients for the lawn. Always mulch with your

highest engine (blade) speed as this will

provide the best recutting action of the blades.

• Avoid cutting your lawn when it is wet.

Wet grass tends to form clumps and interferes with the mulching action. The

best time to mow your lawn is the early aftemoon. At this time the grass has

dried and the newly cut area will not be

exposed to the direct sun.

• For best results, adjust the lawn mower

cutting height so that the lawn mower

cuts off only the top one-third of the grass

blades. If the lawn is overgrown it will be necessary to raise the height of cut to

reduce pushing effort and to keep from

overloading the engine and leaving clumps of mulched grass. For extremely

heavy mulching, reduce your width of

cut, mow slowly and raise the rear of the lawn mower one wheel adjuster setting

higher than the front.

• Certain types of grass and grass condi-

tions may require that an area be mulched a second time to completely hide the clippings. When doing a second

cut, mow across or perpendicular to the first cut path.

• Change your cutting pattern from week to

week. Mow north to south one week then

change to east to west the next week,

This will help prevent matting and grain-

ing of the lawn.

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE

NOTE: Although multi--viscosity oils

(5W30, 10W30 etc.) improve starting in cold weather, these multi--viscosity oils will result in increased oil consumption when used above 32°F. Check your

engine oil level more frequently to avoid possible engine damage from running low on oil.

Change the oil after every 25 hours of oper-

ation or at least once a year if the lawn

mower is not used for 25 hours in one year.

Check the crankcase oil level before start-

ing the engine and after each five (5) hours of continuous use. Tighten oil plug securely each time you check the oil level.
