STORAGE
.... ii i
Prepare your chipper-vacuum for storage at the end
of the season or if the unit will not be used for 30 days
or more.
WARNING: NEVER STORE MACHINE
WITH FUEL IN THE FUEL TANK INSIDE
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).
ENGINE
.... i
e 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 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,
e Drain 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.
o If 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.
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.
e Replace your gasoline can if your can starts to rust.
Rust and/or dirt in your gasoline will cause problems,
o Store 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.
