TILLER

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 gas- oline 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.

TILLER

1.Clean entire tiller (See "CLEANING" in

the Maintenance section of this man- ual).

2.Inspect and replace belts, if necessary

(See belt replacement instructions in

the Service and Adjustments section of this manual).

3.Lubricate as shown in the Maintenance section of this manual.

4.Be sure that all nuts, bolts and screws

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

5.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 stor- age. Also, 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 en- gine and letting 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 minimizing the formation of fuel gum deposits during storage. Add stabilizer to gasoline in fuel tank or stor- age 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 carbu- retor. 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

1.Remove spark plug.

2.Pour 1 ounce (29 ml) of oil through spark plug hole into cylinder.

3.Pull starter handle slowly several 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 protec- tive 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 en- gine and exhaust areas are still warm.
