ENGINE
FUEL SYSTEM
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, 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.
1. Drain the fuel tank.
2. 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.

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.
,q, 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
