STORAGE

ENGINE OIL

Drain oil (with engine warm) and replace with clean oil.  (See 
“ENGINE” in the Maintenance section of this man ual).

CYLINDER(S)

•      Remove spark plug.
•     Pour 1 ounce (29 ml) of oil through spark plug hole 

into cylinder.

•     Pull starter handle slowly several times to distribute 

oil.

•      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 pro tec tive cover that 

does not retain moisture.  Do not use plastic.  Plastic 
cannot breathe which allows con den sa tion to form and 
will cause your unit to rust.

IMPORTANT: 

NEVER COVER TILLER WHILE ENGINE AND 

EXHAUST AREAS ARE STILL WARM.

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

WARNING:  Never store the tiller with 
gasoline in the tank inside a build ing 
where fumes may reach an open fl ame 
or spark.  Allow the engine to cool before 
storing in any enclosure.

TILLER

•         Clean entire tiller (See “CLEANING” in the Maintenance 

section of this manual).

•     Inspect and replace belts, if nec es sary (See belt re-

 place ment in struc tions in the Service and Ad just ments 
section of this manual).

•      Lubricate as shown in the Maintenance section of this 

manual.

•     Be sure that all nuts, bolts and screws are securely 

fastened.  Inspect moving parts for damage, break age 
and wear.  Replace if necessary.

•     Touch up all rusted or chipped paint surfaces; sand 

lightly before painting.

ENGINE

FUEL SYSTEM

IMPORTANT: 

IT IS IMPORTANT TO PREVENT GUM DEPOSITS 

FROM FORMING IN ESSENTIAL FUEL SYSTEM PARTS SUCH 
AS THE 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.

•      Drain the fuel tank.
•     Start the engine and let it run until the fuel lines and 

car bu re tor are empty.

•         Never use engine or carburetor cleaner products in the 

fuel tank or permanent.

NOTE: 

 Fuel stablizer 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 stablizer
container. Run engine at least 10 minutes after adding
stablizer to allow the stabilizer to reach the carburetor. 
Do not drain the gas tank and carburetor if using fuel
stabilizer.
