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 engine 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 mini-
mizing the formation of fuel gum deposits during stor age.
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 oil (with engine warm) and replace with clean en-
gine 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 condensation to form
and will 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 build-
ing where fumes may reach an open
flame or spark. Allow the engine to cool
before storing in any enclosure.
