STORAGE
Prepare your snow thrower for storage at the end of
the season or if the unit will not be used for 30 days or
more.
A
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, ELEC­
TRIC MOTORS, ETC.
NOTE: A yearly check-up by your local Sears Service
Center is a good way to make certain your snow
thrower will provide maximum performance for the
next season.
SNOW THROWER
• Clean the snow thrower thoroughly.
• Wipe unit with an oiled rag to prevent rust (use a
light oil or silicone).
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 STOR­
AGE. ACIDIC GAS CAN DAMAGE THE FUEL SYS­
TEM 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 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 carburetor. Do not drain the gas tank and carbure­
tor if using fuel stabilizer.
• Drain all the oil from the crankcase (this should be
done after the engine has been operated and is still
warm) and refill the crankcase with fresh oil.
• 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 oil into cylinder and crank slowly
to distribute oil. Replace 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 prob­
lems.
• 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 oil or silicone.
SERVICE & ADJUSTMENT
A
WARNING: ALWAYS STOP ENGINE
AND DISCONNECT SPARK PLUG WIRE
AND MOVE IT AWAY FROM SPARK
PLUG BEFORE PERFORMING ANY
ADJUSTMENTS OR REPAIRS.
SHAVE PLATE AND SKID SHOES
• The shave plate and skid shoes on the bottom of
the snow thrower are subject to wear. They should
be checked periodically and replaced when neces­
sary.
• To remove skid shoes, remove the four carriage
bolts, belleville washers and hex nuts which attach
them to the snow thrower. Reassemble new skid
shoes with the four carriage bolts, belleville wash­
ers (cupped side goes against skid shoes) and hex
nuts. Make certain the skid shoes are adjusted to
be level.
• To remove shave plate, remove the carriage bolts,
belleville washers and hex nuts which attach it to
the snow thrower housing. Reassemble new shave
plate, making sure heads of the carriage bolts are
to the inside of the housing. Tighten securely.
