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 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 drain 
the gas tank and carburetor if using fuel stabilizer.

Drain oil (with engine warm) and replace with clean en-
gine oil.  (See “ENGINE” in the Maintenance section of 
this manual).

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.

•      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.

Immediately prepare your lawn mower for storage at the end of the season or if the unit will not be used for 30 days or  more. 

When lawn mower is to be stored for a period of time, clean 
it thoroughly, remove all dirt, grease, leaves, etc.  Store in 
a clean, dry area.

1.   Clean entire lawn mower (See “CLEANING” in the 

Maintenance section of this manual).

2.    Lubricate as shown in the Maintenance section of this 

manual.

3.   Be sure that all nuts, bolts, screws, and pins are se-

curely fastened.  Inspect   moving parts for damage, 
breakage and wear.  Replace if necessary.

4.   Touch up all rusted or chipped paint surfaces; sand 

lightly before painting.

You can fold your lawn mower handle for storage.

1.    Squeeze the bottom ends of the lower handle toward 

each other until the lower handle clears the handle 
bracket, then move handle forward.

2.    Loosen upper handle mounting bolts enough to allow 

upper handle to be folded back.

IMPORTANT:  WHEN FOLDING THE HANDLE FOR STORAGE 
OR TRANSPORTATION, BE SURE TO FOLD THE HANDLE AS 
SHOWN OR YOU MAY DAMAGE THE CONTROL CABLES.

•      When setting up your handle from the storage position, the 

lower han dle will automatically lock into mow ing position.
