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

operation or at least once a year if the

lawn mower is not used for 25 hours in

one year.

carburetorproblems,take yourlawn mowerto

an authorizedservicecenterfor repairor

adjustment.

IMPORTANT: Never tamper with the

engine governor, which is factory set for

proper engine speed. Overspeeding the

engine above the factory high speed

setting can be dangerous, if you think the

engine-governed high speed needs

adjusting, contact your nearest authorized

service center, which has proper

equipment and experience to make any

necessary adjustments.

ENGINE SPEED

Yourenginespeed has been factoryset Do

not attemptto increaseenginespeedor it

may resultinpersonal injury. If youbelieve

storageat the end of the seasonor ifthe unit

willnotbe used for 30 daysor more.

of time, cleanit thoroughly,removeall dirt,

grease, leaves,etc. Store ina clean, dryarea.

•Clean entire lawn mower (See "CLEAN-

ING"inthe Maintenancesectionofthis

manual).

sectionof thismanual.

FUEL SYSTEM

IMPORTANT: tt is important to prevent

gum deposits from forming in essential

fuel system parts such as carburetor, fue!

filter, fuel hose, or tank during storage.

Also, experience indicates that alcohol

blended fuels (called gasohol or using

ethanol or methanol) can attract moistur_

which leads to separation and formation

of acids during storage. Acidic gas can

damage the fuel system of an engine

while in storage.

•Drain the fuel tank.

•Start the engine and let it run until the

fuel lines and carburetor are empty.

•Never use engine or carburetor cleane

products in the fuel tank or permanent

damage may occur.

•Use fresh fuel next season.

NOTE: Fuel stabilizer is an acceptable

alternative in minimizing the formation of

fuel gum deposits during storage. Add

stabilizer to gasoline in fuel tank or

storage container. Always follow the mix

ratio found on stabilizer container. Run

engine at least 10 minutes after adding

stabilizer to allow the stabilizer to reach

the carburetor. Do not drain the gas tank

and carburetor if using fuel stabilizer.

ENGINEOIL

Drain oil (with engine warm) and replace

with clean engine oil. (See "ENGINE' in

the Maintenance 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.

OTHER

•Do not store gasoline from one season

to another.

•Replace your gasoline can if your can

starts to rust. Rust and/or dirt in your

gasoline will cause problems.

•If possible, store your unit indoors and

cover it to give protection from dust and

dirt.

•Cover your unit with a suitable protec-

tive cover that does not retain moisture.

Do not use plastic. Plastic cannot

breathe which allows condensation to

form and will cause your unit to rust.

IMPORTANT: Never cover mower while

engine and exhaust areas are still warm.

_I_CAUTION: Never store the lawn mower

with gasoline in the tank inside a building

where fumes may reach an open flame or

spark. Allow the engine to cool before

storing in any enclosure.
