STORAGE

STORAGE

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 building where fumes may reach an open flame or spark. Allow the en- gine 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 necessary (See belt re- placement instructions in the Service and Adjustments 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, breakage 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.

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.

ENGINE OIL

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

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 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 TILLER WHILE ENGINE AND EXHAUST AREAS ARE STILL WARM.
