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.
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.
• Empty the fuel tank by starting the en-
gine and letting 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 empty the gas tank
and carburetor if using fuel stabilizer.
ENGINE OIL
Drain oi! (with engine warm) and replace
with clean engine oil. (See "ENGINE" in
the Maintenance section of this manual).
CYLINDER
1. Remove spark plug.
2. Pour one ounce of oi! through spark
plug hole into cylinder.
3. Pull starter handle slowly a few times
to distribute oil.

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 protect it 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.
Ai:_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.
