Preparing Engine; Off-Season Storage; Preparing Snow Thrower - Sears Craftsman 247.88790 Manual De Uso

���� �����
If the snow thrower will not be used for 30 days or longer, or if it is the
end of the snow season when the last possibility of snow is gone, the
equipment needs to be stored properly. Follow storage instructions
below to ensure top performance from the snow thrower for many
more years.

Preparing Engine

WARNING: Never store snow thrower with
fuel in tank indoors or in poorly ventilated
areas, where fuel fumes may reach an open
flame, spark or pilot light as on a furnace,
water heater, clothes dryer or gas appli-
ance.
NOTE: It is important to prevent gum deposits from forming in
essential fuel system parts of the engine such as the carburetor, fuel
filter, fuel hose or tank during storage.
CAUTION: Alcohol blended fuels (called gasohol or using ethanol or
methanol) can attract moisture which leads to separation and forma-
tion of acids during storage. Acidic gas can damage the fuel system of
an engine while in storage.

OFF-SEASON STORAGE

����������
To avoid engine problems, the fuel system should be emptied before
storage for 30 days or longer. Follow these instructions to prepare your
snow thrower for storage:
WARNING: Drain fuel into an approved
container outdoors, away from any open
flame. Be certain engine is cool. Do not
smoke. Fuel left in engine during warm
weather deteriorates and will cause serious
starting problems.
1. Remove all gasoline from the carburetor and the fuel tank to
prevent gum deposits from forming on these parts and harming the
engine.
2. Run the engine until the fuel tank is empty and it stops due to lack
of fuel.
3. Drain carburetor by pressing upward on bowl drain, located below
the carburetor cover. See figure at left.
WARNING: Do not drain carburetor if using
fuel stabilizer. Never use engine or carbure-
tor cleaning products in the fuel tank or
permanent damage may occur.
NOTE: Fuel stabilizer (such as STA-BIL) is an acceptable alternative
in minimizing the formation of fuel gum deposits during storage. Add
stabilizer to gasoline in fuel tank or storage container. Always follow
mix ratio found on stabilizer container. Run engine at least 10 minutes
after adding stabilizer to allow it to reach the carburetor. Do not drain
carburetor if using fuel stabilizer.
4. Remove the spark plug and pour one (1) ounce of engine oil
through the spark plug hole into the cylinder. Cover spark plug hole
with a rag and crank the engine several times to distribute the oil.
Replace spark plug.

Preparing Snow Thrower

1. When storing the snow thrower in an unventilated or metal storage
shed, care should be taken to rustproof the equipment. Using a
light oil or silicone, coat the equipment, especially any chains,
springs, bearings and cables.
2. Remove all dirt from exterior of engine and equipment.
3. Follow lubrication recommendations in the Maintenance section of
this manual.
4. Store equipment in a clean, dry area.
