BEFORE ATTEMPTING TO OPERATE YOUR SNOW THROWER. FAILURE TO COMPLY WITH
THESE INSTRUCTIONS MAY RESULT IN PERSONAL INJURY. WHEN YOU SEE THIS SYMBOLHEED ITS WARNING.
WARNING:
The Engine Exhaust from this product contains chemicals known to the State
of California to cause cancer, birth defects or other reproductive harm.
DANGER:
Your snow thrower was built to be operated according to the rules for safe
operation in this manual. As with any type of power equipment, carelessness or error on the
part of the operator can result in serious injury. If you violate any of these rules, you may
cause serious injury to yourself or others.
1. TRAINING
• Read this operator's manual carefully in its entirety
before attempting to assemble or operate this
machine. Be completely familiar with the controls
and the proper use of this machine before
operating it. Keep this manual in a safe place for
future and regular reference and for ordering
replacement parts.
• Never allow children under 14 years old to operate
a snow thrower. Children 14 years old and over
should only operate snow thrower under close
parental supervision. Only persons well acquainted
with these rules of safe operation should be
allowed to use your snow thrower.
• No one should operate this unit while intoxicated
or while taking medication that impairs the senses
or reactions.
• Keep the area of operation clear of all persons,
especially small children and pets.
• Exercise caution to avoid slipping or falling,
especially when operating in reverse.
1. PREPARATION
• Thoroughly inspect the area where the equipment
is to be used and remove all door mats, sleds,
boards, wires and other foreign objects.
• Disengage all clutches and shift into neutral before
starting engine.
• Do not operate equipment without wearing
adequate winter outer garments. Do not wear
jewelry, long scarfs or other loose clothing which
could become entangled in moving parts. Wear
footwear which will improve footing on slippery
surfaces.
• Before working with gasoline, extinguish all
cigarettes and other sources of ignition. Check the
fuel before starting the engine. Gasoline is an
extremely flammable fuel. Do not fill the gasoline
tank indoors, while the engine is running, or until
engine has been allowed to cool at least two
minutes. Replace gasoline cap securely and wipe
off any spilled gasoline before starting the engine
as it may cause a fire or explosion.
• Use a grounded three wire plug-in for all units with
electric drive motors or electric starting motors.
• Adjust collector housing height to clear gravel or
crushed rock surface.
• Never attempt to make any adjustments while
engine is running (except where specifically
recommended by manufacturer).
• Let engine and machine adjust to outdoor
temperature before starting to clear snow.
• Always wear safety glasses or eye shields during
operation or while performing an adjustment or
repair, to protect eyes from foreign objects that
may be thrown from the machine in any direction.
2. OPERATION
• Do not put hands or feet near or under rotating
parts. Keep clear of discharge opening and auger
at all times.
• Exercise extreme caution when operating on or
crossing gravel drives, walks, or roads. Stay alert
for hidden hazards or traffic. Do not carry
passengers.
• After striking a foreign object, stop the engine,
remove wire from spark plug, and thoroughly
inspect the snow thrower for any damage. Repair
the damage before restarting and operating the
snow thrower.
2
• If the snow thrower should start to vibrate
abnormally, stop the engine and check
immediately for the cause. Vibration is generally a
warning of trouble.
• Stop engine whenever you leave the operating
position, before unclogging the collector/impeller
housing or discharge guide, and making any
repairs, adjustments, or inspections. Never place
your hand in the discharge or collector openings.
Use a stick or wooden broom handle to unclog the
discharge opening.
• Take all possible precautions when leaving the unit
unattended. Disengage the collector/impeller, shift
into neutral, stop the engine, and remove the key.
• When cleaning, repairing, or inspecting, make
certain collector/impeller and all moving parts have
stopped. Disconnect spark plug wire and keep
away from plug to prevent accidental starting.
• Do not run engine indoors, except when starting
engine and transporting snow thrower in or out of
building. Open doors. Exhaust fumes are
dangerous.
• Do not clear snow across the face of slopes.
Exercise extreme caution when changing direction
on slopes. Do not attempt to clear steep slopes.
• Never operate snow thrower without guards,
plates, or other safety protection devices in place.
• Never operate snow thrower near glass enclosure,
automobiles, window wells, drop off, etc., without
proper adjustments of snow thrower discharge
angle. Keep children and pets away.
• Do not overload machine capacity by attempting to
clear snow at too fast a rate.
• Never operate the machine at high transport
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.
WARNING - YOUR RESPONSIBILITY:
Restrict the use of this power machine to persons
who read, understand and follow the warnings and instructions in this manual and on the machine.

thrower so the flat side of the handle is against
the frame. Secure bottom hole in handle to
snow thrower using hex bolt (B) and lock
washer (C). There are weld nuts welded to the
inside of the frame for these bolts. See Figure
4. Do not tighten at this time.
2. Attach the left handle in the same manner. Do
not tighten at this time.

the flat side of the clutch grips are against the
pivot rod cover. Thread hex nuts (D) onto each
end of the rod. Tighten nuts allowing the clutch
grips to move freely on pivot rod. See Figure 6.
3. Insert clutch grip and rod assembly into handle
tabs. Clutch grips must sit on top of the

selector plate.
NOTE:
the operator. Secure shift lever to the shift lever
spring using two hex bolts (G) and hex lock nuts
(H). Tighten both bolts finger tight. At this point the
shift lever and shift lever spring are not against each
other. As you tighten the bolts and nuts with two
7/16" wrenches they will pull together. See Figure 9.
3. Tighten all hardware assembled to this point.

1. Thread hex nuts (J) onto the “Z” fittings (R) (see
inset, Figure 10). Insert “Z” fitting into hole in
clutch grips.
2. Route the left cable between engine and speed
selector plate and then between handle panel
and clutch lever pivot rod before threading onto
the left “Z” fitting. Assemble the right cable
using the same route.
3. Correct adjustment on cables is minimal slack
but not tight. Tighten hex nuts when adjustment
is correct.
NOTE:
adjusted correctly, the wheels will tend to turn. If the
left hand lockout cable is not adjusted correctly, the
augers will not stop rotating.

See Figure 13. Place second flat washer on
chute crank, and secure with hairpin clip.
3. Thread one hex nut (D) onto the eyebolt on the
chute crank assembly until there is at least two
inches of threads showing between the nut and
the head of the eyebolt. See Figure 14.
4. Place the eyebolt into the hole located half way
up the left handle. Secure with cupped washer
(N) (cupped side against the handle, see inset,
Figure 14) and hex nut (D).
5. Adjust the chute crank support bracket (see
Figure 13) so that the spiral on the chute crank
fully engages the teeth on the chute assembly.
Tighten the nuts on the chute crank bracket
securely. Tighten the hex nuts on the eyebolt.
