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.

• Empty the fuel tank by starting 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 stablizer is an acceptable alternative in mini-

mizing 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 empty

the gas tank and carburetor if using fuel stabilizer.

STORAGE

TILLER HANDLE STORAGE OPTIONS

The tiller handle assembly can be modified to allow for a

variety of storage positions outlined below.

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.

• Ensure 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.

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 flame or spark. Allow the en-

gine to cool before storing in any enclosure.

CAUTION: Do not start or operate tiller when

handle is in any of these positions.

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.
