Off Season Storage & Troubleshooting; Preparing Engine; Preparing Snow Thrower - Craftsman 247.88455.1 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.

Preparing Engine

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 stabalizer.
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 ventilated 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 prob-
lems.
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.
OFF-SEASON STORAGE
• When storing the snow thrower in an unventilated or metal storage
• Remove all dirt from exterior of engine and equipment.
• Follow lubrication recommendations.
• Store equipment in a clean, dry area.
