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.
NOTE: Refer to the engine manual for more information
on preparing the snow thrower engine for storage.
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 on page 11.
4. Store equipment in a clean, dry area.
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 appliance.
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 formation of acids
during storage. Acidic gas can damage the fuel
system of an engine while in 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.
WARNING: Do not drain carburetor if
using fuel stabilizer. Never use engine
or carburetor cleaning products in the
fuel tank or permanent damage may
occur.
NOTE: Fuel stabilizer (such as STA-BIL) 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 carburetor. Do not drain carburetor if using fuel
stabilizer.
