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, 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.
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 foupd 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
1. Remove spark plug.
2. Pour one ounce (29 ml) of oil through
spark plug hole into cylinder.
3. Pull starter handle slowly a few times
to distribute oil.
4. 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
protective cover that does not retain
moisture. Do not use plastic. Plastic
cannot breathe which allows conden-
sation to form and will cause your unit
to rust.
IMPORTANT: Never cover mower while
engone and exhaust areas are still
warm.
_, CAUTION:Nevei" 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 stodng in any enclosure.
