Preparing the 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.
Also experience
indicates
that 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:
Remove all gasoline from the carburetor
and the
fuel tank to prevent gum deposits from forming on
these parts and harming the engine.

WARNING:
Drain fuel into 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.
Run the engine until the fuel tank is empty and it
stops due to lack of fuel.
Drain carburetor
by pressing upward on bowl drain,
located below the carburetor
cover. See Figure 38.

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
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.
Do not drain carburetor
if using
fuel stabilizer.
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.
Preparing the Snow Thrower
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.
Remove all dirt from exterior of engine and
equipment.
Follow lubrication
recommendations
on page 17.
Store in a clean, dry area.
