STORAGE

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

LAWN MOWER

When lawn mower is to be stored for a period of time, clean it thoroughly, remove all dirt, grease, leaves, etc. Store in a clean, dry area.

1.Clean entire lawn mower (See “CLEANING” in the Maintenance section of this manual).

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

3.Be sure that all nuts, bolts, screws, and pins are se-

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

4.Touch up all rusted or chipped paint surfaces; sand lightly before painting.

HANDLE (See Figs. 16 and 17)

You can fold your lawn mower handle for storage.

FUEL SYSTEM

IMPORTANT: IT IS IMPORTANTTO PREVENT GUM DEPOSITS FROM FORMING IN ESSENTIAL FUEL SYSTEM PARTS SUCH AS 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 MOISTUREWHICH LEADSTO SEPARATION AND FORMATION OF ACIDS DURING STORAGE. ACIDIC GAS CAN DAMAGE THE FUEL SYSTEM OF AN ENGINE WHILE IN STORAGE.

1.Drain the fuel tank.

2.Start 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 stabilizer 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 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 en- gine oil. (See “ENGINE” in the Maintenance section of this manual).

CYLINDER

1.Remove spark plug.

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

3.Pull starter handle slowly a few 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 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 MOWER WHILE ENGINE AND EXHAUST AREAS ARE STILL WARM.

CAUTION: Never store the lawn mower with gasoline in the tank inside a build- ing where fumes may reach an open flame or spark. Allow the engine to cool before storing in any enclosure.
