Prepare your chipper-vacuumfor storage at the end

of the season or if the unit will not be used for 30 days or more.

WITH FUEL IN THE FUEL TANK INSIDE

WARNING: NEVER STORE MACHINE

OF BUILDING WHERE FUMES MAY REACH AN OPEN FLAME OR SPARK, OR

WHERE IGNITION SOURCES ARE PRESENT SUCH AS HOT WATER AND SPACE HEATERS, FURNACES, CLOTHES DRYERS, STOVES, ELECTRIC MOTORS,

ETCo

NOTE: A yearly check-up by your local Sears Service Center is a good way to make certain your chipper- vacuum will provide maximum performance for the

next season.

CHIPPER-VACUUM

•Clean the chipper-vacuum thoroughly.

•Wipe unit with an oiled rag to prevent rust (use a light oil or silicone).

eDrain 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 fuel tank or permanent damage may occur.

•Use fresh fue! 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 carburetor. Do not drain the gas tank and carbure- tor if using fuel stabilizer,

eDrain all the oit from the crankcase (this should be done after the engine has been operated and is still warm) and refill the crankcase with fresh oil.

oIf you have drained the fuel tank, protect the inside of the engine as follows. Remove spark plug, pour approximately 1/2 ounce (approximately one table- spoon) of engine oit into cylinder and crank slowly to distribute oil. Replace spark plug.

ENGINE

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 INDICATES THAT ALCOHOL BLENDED FUELS (CALLED GASOHOL

OR USING ETHANOL OR METHANOL) CAN ATTRACT MOISTURE WHICH LEADS TO SEPARA-

TION AND FORMATION OF ACIDS DURING STORAGE. ACIDIC GAS CAN DAMAGE THE FUEL SYSTEM OF AN ENGINE WHILE IN STORAGE.

OTHER

•Do not store gasoline from one season to another.

eReplace your gasoline can if your can starts to rust. Rust and/or dirt in your gasoline will cause problems,

oStore unit in a clean, dry area. Do not store next to corrosive materials, such as fertilizer.

NOTE: If storing in an unventilated or metal storage shed, be certain to rustproof the equipment by coating with a light oi! or silicone.
