ENGINE

FUELSYSTEM
IMPORTANT: It is important to prevent

gum deposits from forming in essential

fuel system parts such as carburetor, fuel
filter, fuel hose, or tank during storage.

Also, 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 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 cleaner

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.
ENGINE OIL
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 wilt cause your unit to rust.

IMPORTANT: Never cover mower while
engine and exhaust areas are still warm.
^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.
