Off-Season Storage - Craftsman professional 247.88045 Manual Del Operador

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.

Short-Term Storage
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 short-term storage (15-30 days). To prevent this, treat
the fuel system using a fuel stabilizer.
Fuel stabilizer (such as STA-BIL™ or ULTRA-FRESH™) is an accept-
able 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 carbure-
tor.
Warning
Never store snow thrower with fuel in tank indoors or in poorly venti-
lated areas, where fuel fumes may reach an open flame, spark or pilot
light as on a furnace, water heater, clothes dryer or gas appliance.
CaUTion
Alcohol blended fuels (called gasohol or using ethanol or methanol)
can attract moisture which leads to separation and formation of acids
during storage. Acidic gas can damage the fuel system of an engine
while in storage.
Long-Term Storage
To avoid engine problems, the fuel system should be emptied before
storage for 30 days or longer.
Warning
Fuel left in engine during warm weather deteriorates and will cause
serious starting problems.
1. Run the engine until the fuel tank is empty and it stops due to lack
of fuel. Do not attempt to pour fuel from the engine.
Warning
Never use engine or carburetor cleaning products in the fuel tank or
permanent damage may occur.
2. 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.

When storing the snow thrower in an unventilated or metal stor-
age 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.
Remove all dirt from exterior of engine and equipment.
Follow lubrication recommendations.
Store equipment in a clean, dry area.
