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.

3. 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.

4. 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.

power cord and plug, and is designed to
operate on 120 volt AC household
current. It must be properly grounded at
all times to avoid the possibility of
electric shock which may be injurious to
the operator. Follow all instructions
carefully. Determine that your house
wiring is a three wire grounded system.
Ask a licensed electrician if you are not
certain. If your house wiring system is
not a three-wire grounded system, do
not use this electric starter under any
conditions. If your system is grounded
and a three-hole receptacle is not
available at the point your starter will
normally be used, one should be
installed by a licensed electrician.

When connecting the power cord, always connect

adjustment, the adjustment can be physically
checked as follows.

1. With the snow thrower tipped forward (be
certain to drain the oil and gasoline or drain the
oil and place plastic film under the gas cap if the
snow thrower has already been operated),
remove the frame cover underneath the snow
thrower by removing six self-tapping screws.

2. With the traction drive clutch released, there
must be clearance between the friction wheel
and the drive plate in all positions of the shift
lever. With the traction drive clutched engaged,
the friction wheel must contact the drive plate.
See Figure 18.

certain to remove it.

AUGER CLUTCH ADJUSTMENT

To adjust the auger clutch, refer to Final Assembly
and Adjustments section on page 9.

CARBURETOR ADJUSTMENT

WARNING: If any adjustments are

made to the engine while the engine is
running (e.g. carburetor), keep clear of all
moving parts. Be careful of heated

surfaces and muffler.

Minor carburetor adjustment may be required to
compensate for differences in fuel, temperature,
altitude and load.
Refer to the separate engine manual packed with
your unit for carburetor adjustment information.

DRIVE WHEELS

The wheels may be adjusted for two different
methods of operation. The adjustment is made by
placing the klick pins in one of two different holes on
the right side of the unit. See Figure 19.

1. One Wheel Driving—On the right side of the
unit, place klick pin in the outside axle hole only.
Do not place pin through wheel hub. This
position gives power drive to the left wheel only,
making the unit easier to maneuver.

2. Both Wheels Driving—Rotate wheel assembly
to align hole in hub with inner hole on axle
shaft. Insert klick pin in hole. Outer axle shaft
hole should be visible. See Figure 19.

AUGERS

The augers are secured to the spiral shaft with two
shear bolts and hex lock nuts. See Figure 21. If you
hit a foreign object or ice jam, the snow thrower is
designed so that the bolts will shear.
If the augers will not turn, check to see if the bolts
have sheared. A replacement shear bolt (P) and
hex lock nut (Q) have been provided with the snow
thrower. When replacing bolts, spray an oil lubricant
into shaft before inserting new bolts.

SHAVE PLATE AND SKID SHOES

The shave plate and skid shoes on the bottom of
the snow thrower are subject to wear. They should
be checked periodically and replaced when
necessary.

• To remove skid shoes, remove the four
carriage bolts, cupped washers and hex nuts
which attach them to the snow thrower.
Reassemble new skid shoes with the four
carriage bolts, cupped washers (cupped side
goes against skid shoes) and hex nuts.
