speeds on slippery surfaces. Look behind and use
care when backing.
• Never direct discharge at bystanders or allow
anyone in front of unit.
• Disengage power to collector/impeller when
transporting or not in use.
• Use only attachments and accessories approved
by the manufacturer of snow thrower (such as
wheel weights, counter weights, cabs, etc.).
• Never operate the snow thrower without good
visibility or light. Always be sure of your footing
and keep a firm hold on the handles. Walk, never
run.
• Muffler and engine become hot and can cause a
burn. Do not touch.
3. MAINTENANCE AND STORAGE
• Check shear bolts, engine mounting bolts, etc., at
frequent intervals for proper tightness to be sure
equipment is in safe working condition.
• Never store the machine with fuel in the fuel tank
inside a building where ignition sources are
present, such as hot water and space heaters,
clothes dryers, and the like. Allow engine to cool
before storing in any enclosure.
• Always refer to operator's manual instructions for
important details if snow thrower is to be stored for
an extended period.
• Run machine a few minutes after throwing snow to
prevent freeze up of collector/impeller.
• Check clutch controls periodically to verify they
engage and disengage properly and readjust if
necessary. Refer to operator's manual for
adjustment instructions.

SECTION 11: OFF-SEASON STORAGE
WARNING: Never store engine 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 other gas appliance.
If unit is to be stored over 30 days, prepare for
storage as follows:
1.Remove all 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.
WARNING: Drain fuel into approved
container outdoors, away from open
flame. Be certain engine is cool. Do not
smoke. Fuel left in engine during warm
weather deteriorates and will cause
serious starting problems.
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 carburetor. Do not drain carburetor
if using fuel stabilizer.
• Remove all dirt from exterior of engine and
equipment.
• Remove spark plug and pour one (1) ounce
of engine oil through spark plug hole into
cylinder. Crank engine several times to
distribute oil. Replace spark plug.
• Follow lubrication recommendations on
page 15.
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.
