gasoline in the tank inside a building

where fumes may reach an open flame CAUTION: Never store the tractor with or spark. A!low the engine to cool

before storing in any enclosure.

TRACTOR

Remove mower from tractor for winter storage. When mower is to be stored for a period of time, clean it thor- ougfily, remove all dirt, grease, leaves, etc. Store in a clean, dry area.

=Clean entire tractor (See "CLEANING" in the Customer Responsibilities 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 Customer Responsibilities section of this manual.

-Be sure 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.

BATTERY

®Fully charge the battery for storage.

. After a period of time in storage, battery may require recharging.

,To help prevent corrosion and power leakage during long periods of storage, battery cables should be

disconnected and battery cleaned thoroughly (see "TO CLEAN BATTERY AND TERMINALS" in the Cus- tomer Responsibilities section of this manual).

-After cleaning, leave cables disconnected and place cableswhere they cannot come in contact with battery terminals.

Be sure battery drain tube is securely attached.

If battery is removed from tractor for storage, do not store battery directly on concrete or damp surfaces.

ENGINE

FUEL SYSTEM

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 INDrCATES 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 carburetor are empty.

,Never use engine or carburetor cleaner products in the fue! tank or permanent damage may occur.

Use fresh fuel next season.

NOTE: Fue! stabilizer is an acceptable alternative in minimizing 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.

ENGINE OIL

Drain oil (with engine warm) and replace with clean engine oil. (See "ENGINE" in the Customer Responsibilities section of this manual).

CYUNDERS

Remove spark plug(s).

,Pour one ounce of oil through spark plug hole(s) into cylinder(s).

=Turn ignition key to"START" position for a few seconds to distribute oil.

,Replace with new spark plug(s).

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 wil! cause problems.

,If possible, store your tractor indoors and cover it to give protection from dust and dirt.

Cover your tractor 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 tractor to rust.

IMPORTANT: NEVER COVER TRACTOR WHILE ENGINE AND EXHAUST AREAS ARE STILL WARM.
