ENGINE

FUEL SYSTEM
IMPORTANT: 

IT IS IMPORTANT TO PREVENT GUM 

DEPOSITS FROM FORMING IN ESSENTIAL 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 DA-
MAGE 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.

CYLINDER

1.Remove spark plug.
2.Pour one ounce (29ml) 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. 

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.

IMPROTANT:

 NEVER COVER MOWER 

WHILE ENGINE AND EXHAUST AREAS 
ARE STILL WARM.

utes after adding stabilizer to allow the stabilizer to 
reach the carburetor. Do not drain the gas tank and 
carburetor if using fuel stabilizer. 
Drain oil (with engine warm) and replace with clean 

engine oil. (See 

ENGINE

 in the CUSTOMER RES-

PONSIBILITIES section of this manual).

NOTE: Fuel stabilizer is an acceptable alternative 
in minimizing the formation of fuel gum deposits dur-
ing 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 min-
