• Reinstall engine oil cap end lighten.

•Chenge the oil after every 25 hours of

operation or each season. You may need

to change the oil more often under dusty,

dirtyconditions.

GAS

•Fillfuel tank. Use fresh, clean, regular

unleaded gasoline with a minimum lof 87

octane. (Use of leaded gasoline will

increase carbon and load oxide deposits

and reduce valve I'Ve). Do not mix oil with

gasoline. Purchase 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 loads

to separation and formation of acids during

storage. Acidic gas can damage the fuel

system of an engine while in storage. To avoid

engine problems, the fuel system should be

emptied before storage of 30 days or longer.

Drain the gas tank, start the engine and let it

run until the fuel lines and carburetor are

empty. Use fresh fuel next season. See

Storage Instructions for addlti_, information.

Never use engine or carburetor cleaner

products in the fuel tank or permanent

damage may occur.

TO START ENGINE

• To start a cold engine, push primer three

(3) 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

necessary to repeat pdmingsteps. In

warmer weather over priming may cause

flooding and engine willnot start. Ifyou do

flood engine, wait a few minutes before

attempting to start and do not repeat

priming steps.

MOWING TIPS

•Formostcuttingconditionsand better

baggingperformance,the enginespeed

shouldbe set inthe fast position.

•Undercertainconditions,suchas when

mowingverytallgrass,raisethe mower

heightonthe firstcutto reducepushing

effort,to avoidoverheatingthe engine,and

toavoidleavingclumpsofgrass clippings.

Make the second cut to the desired height.

For extremely heaw cutting, reduce the

width ofcut.

Pores in cloth grass catchers can become

filledwith dirtand dust with use and the

catcher willcollect less grass. To prevent

this, regularly hose catcher off with water

and lot dry before use.

MULCHING MOWING TIPS

IMPORTANT: Forbestperfo_, keep
