Off-Season Storage
WARNING: Never store the machine or
fuel container indoors where there is an
open flame, spark, or pilot light such as on
water heater, furnace, clothes dryer, or
other gas appliance.
WARNING: Drain fuel into an approved
container outdoors, away from an open
flame. Allow engine to cool. Extinguish
cigarettes, cigars, pipes, and other
sources of ignition prior to draining fuel.
Fuel left in engine for extended periods
deteriorates and will cause starting
problems.
If unit is to be stored over 30 days, prepare for storage
as follows:
Remove gasoline from carburetor and fuel tank to
prevent gum deposits from forming on these parts
and causing possible malfunction of engine.
Run engine until fuel tank is empty and engine
stops due to lack of fuel.
Drain carburetor by pressing upward on bowl drain,
located below the carburetor cover.
NOTE: Fuel stabilizer is an acceptable alternative in
minimizing the formation of fuel gum deposits during
storage. Do not drain carburetor if using fuel stabilizer.
Wipe equipment with an oiled rag to prevent rust.
Remove spark plug and pour one ounce of engine
oil through spark plug hole into cylinder. Cover
spark plug hole with rag. Crank engine several
times to distribute oil. Replace spark plug.
Follow the lubrication recommendations found in
the Maintenance Section.
Always store the snow thrower in a clean, dry area.
NOTE: When storing any type of power equipment in
an unventilated or metal storage shed, care should be
taken to rust proof the equipment. Using a light oil or
silicone, coat the equipment, especially any chains,
springs, bearings and cables.
