CAUTION: DRAIN FUEL INTO APPROVED
CONTAINER OUTDOORS, AWAY FROM
OPEN FLAME.
STORAGE
CAUTION: NEVER STORE THE ENGINE
WITH FUEL IN THE TANK INDOORS OR
IN AN ENCLOSED, POORLY VENTI-
LATED AREA WHERE FUEL FUMES MAY
REACH AN OPEN FLAME, SPARK OR
PILOT LIGHT AS ON A FURNACE, WA-
TER HEATER, CLOTHES DRYER, ETC.
●
Start the engine and run at SLOW (idle) speed until
the engine stops from lack of fuel.
●
Drain the carburetor by pressing upward on the bowl
drain (See III.33), located below the carburetor cover.
NOTE: Fuel stabilizer (such as STA-BIL) is an accept-
able alternative in minimizing the formation of fuel gum
deposits during storage. Add stabilizer to gasoline in the
fuel tank or storage container. Always follow the mix ratio
found on stabilizer container. Run the 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.
●
Remove the spark plug and squirt one (1) ounce of
engine oil into the cylinder. Pull the recoil starter rope
slowly, allowing the piston to coat the internal engine
parts. Install an old spark plug. This prevents fouling
a new plug with the preservative used to lubricate the
internal parts of the engine. Close the choke and
plug the muffler opening.
OTHER
●
If possible, store your snow thrower indoors and
cover it to give protection from dust and dirt.
●
If the machine must be stored outdoors, block up the
snow thrower to be sure the entire machine is off the
ground.
●
Cover the snow thrower with a suitable protective
cover that does not retain moisture. Do not use
plastic.
IMPORTANT:
NEVER COVER SNOW THROWER
WHILE ENGINE AND EXHAUST
AREAS ARE STILL WARM.
NOTE: Immediately prepare your snow thrower for stor-
age at the end of the season or if the unit will not be used
for 30 days or more.
SNOW THROWER
Thoroughly clean the snow thrower.
●
Lubricate all lubrication points (See the Mainte-
nance section).
●
Be sure that all nuts, bolts and screws are securely
fastened. Inspect all visible moving parts for dam-
age, breakage and wear. Replace if necessary.
●
Touch up all rusted or chipped paint surfaces; sand
lightly before painting.
●
Cover the bare metal parts of the blower housing
auger and the impeller with rust preventative, such
as sprayable lubricant.
NOTE: A yearly checkup or tuneup by a authorized
Service Center is a good way to insure that your snow
thrower will provide maximum performance for the next
season.
ENGINE
IMPORTANT: EMPTYING THE FUEL SYSTEM BE-
FORE STORAGE IS IMPORTANT TO
PREVENT GUM DEPOSITS FROM
FORMING IN ESSENTIAL FUEL SYS-
TEM PARTS SUCH AS THE CARBU-
RETOR, FUEL FILTER, FUEL HOSE
OR TANK DURING STORAGE. ALSO,
EXPERIENCE INDICATES THAT AL-
COHOL BLENDED FUELS (CALLED
GASOHOL OR USING ETHANOL OR
METHANOL) CAN ATTRACT MOIS-
TURE WHICH LEADS TO SEPARA-
TION AND FORMATION OF ACIDS
DURING STORAGE. ACIDIC GAS CAN
DAMAGE THE FUEL SYSTEM OF AN
ENGINE WHILE IN STORAGE.
●
Drain the gasoline from the fuel tank by removing the
fuel line. Drain the fuel and reinstall the fuel line.
