Off-Season Storage
If the snow thrower will not be used for 30 days or longer,
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
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.
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.

Long-Term Storage
Engines stored over 30 days need to be drained of fuel
to prevent deterioration and gum from forming in fuel
system or on essential carburetor parts. If the gasoline in
your engine deteriorates during storage, you may need to
have the carburetor, and other fuel system components,
serviced or replaced.
1. Remove all of the fuel from the fuel tank by running
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.
2. Change the engine oil as instructed in the Maintenance
section of the Engine Operator's Manual included with
the snow thrower.
3. Remove the spark plug and pour one (1) ounce (30 ml)
of clean engine oil through the spark plug hole and into
the cylinder. Cover spark plug hole with a rag and crank
the engine several times to distribute the oil. Replace
spark plug.
WARNING! Never use engine or carburetor
cleaning products in the fuel tank or
permanent damage may occur.
Clean debris from around engine, and under, around, and
behind muffler. Apply a light film of oil on any areas that
are susceptible to rust.
• Store in a clean, dry and well ventilated area away from
any appliance that operates with a flame or pilot light,
such as a furnace, water heater, or clothes dryer. Avoid
any area with a spark producing electric motor, or
where power tools are operated.
• If possible, avoid storage areas with high humidity.
• Keep the engine level in storage. Tilting can cause fuel
or oil leakage.
