(c) Fill fuel tank outdoors with extreme care. Never fill
fuel tank indoors. Replace fuel cap securely and
wipe up spilled fuel.
(d) Never fill containers inside a vehicle or on a truck
or trailer bed with a plastic liner. Always place con-
tainers on the ground, away from your vehicle, before
filling.
(e) When practical, remove gas-powered equipment
from the truck or trailer and refuel it on the ground. If
this is not possible, then refuel such on a trailer with a
portable container, rather than from a gasoline dis-
penser nozzle.
(f) Keep nozzle in contact with the rim of the fuel tank
or container opening at all times, until refueling is
complete. Do not use a nozzle lock-open device.
(g) Replace gasoline cap securely and wipe up spilled
fuel.
(h) If fuel is spilled on clothing, change clothing imme-
diately.
5. Use extension cords and receptacles as specified by
the manufacturer for all units with electric drive
motors or electric starting motors.
6. Adjust the collector housing height to clear gravel or
crushed rock surfaces.
7. Never attempt to make any adjustments while the
engine (motor) is running (except when specifically
recommended by the manufacturer).
8. Let engine (motor) and machine adjust to outdoor
temperatures before starting to clear snow.
9. Always wear safety glasses or eye shields during
operation or while performing an adjustment or repair
to protect eye from foreign objects that may be
thrown from the machine.
19. Never leave a running unit unattended. Always disen-
gage the auger and traction controls, stop engine,
and remove keys.
20. Do not operate the unit while under the influence of
alcohol or drugs.

used to set the ground speed of the snowthrower.
The snowthrower has five forward speeds, 1–5, and
two reverse speeds, 1–2. No neutral position or gate
is required, since the traction drive design automati-
cally provides "neutral" (no forward or reverse move-
ment), whenever the drive control is released.
B. Traction & Free Hand™ Control - This control
engages the traction drive as the lever (B, Figures 3
& 4) is depressed, and disengages the traction drive
when the lever is released. When both levers are
depressed the Free Hand™ control is activated. This

Operation
GENERAL OPERATION
WARNING
This unit is a “two-stage” snowthrower.
CHECKS BEFORE EACH START-UP
The first stage is the auger, which feeds the snow
back into the impeller housing. The second stage
is the impeller, which throws the snow out the
discharge chute. If bodily contact is made with
the auger or impeller when they are rotating,
severe personal injury will occur.
1. Make sure all safety guards are in place and all nuts,
bolts and clips are secure.
2. Check to make sure that the clean-out tool is
attached to the handle on the machine. Do not oper-
ate the machine without the clean-out tool properly
stored on the handle.
To avoid injury, keep others and yourself away
from the auger and the discharge chute whenever
the engine is running. Read and follow all of the
safety rules and warnings in this manual.
3. Check the engine oil level. See your engine owner’s
manual for procedure and specifications.
4. Check to make sure spark plug wire is attached and
spark plug is tightened securely. If necessary, torque
spark plug to 15 ft. lbs.
DANGER
5. Check the fuel supply. Fill the tank no closer than 1/4
to 1/2 inch of top of tank to provide space for expan-
sion. See your engine owner’s manual for fuel recom-
mendations.
Do not clean out discharge chute with hands.
Contact with moving parts inside chute will cause
serious injury. Use clean-out tool provided with
machine. Use the following procedure to remove
objects or clear the chute:
6. Check the scraper bar to make sure it is set at the
desired height. Adjust the skid shoes if necessary.
(See page 15.)
1. Stop the engine. Remove the key
2. Wait 10 seconds to be sure the auger/impeller
blades have stopped rotating.
3. Always use the clean-out tool. DO NOT use your
hands.
7. Check the drive control (B, Figure 3), and Auger
Control (C) for proper operation. If adjustment is
required, see the Service Section for procedures.
8. Check the chute direction control (D, Figure 3) for
proper operation. The discharge chute should rotate
freely in both directions. See the Service Section for
adjustment procedures and troubleshooting.
WARNING
9. Check the chute deflector (E, Figure 3) for proper
operation. The deflector should pivot freely up and
down when the chute deflector knob is loosened. If
adjustment is required, see the Service Section for
procedures.
For your safety, operation on slopes should be in
an up and down direction only. If it becomes
necessary to move across the face of a slope, use
caution and do not blow snow. Be very careful
when changing direction on a slope.
10. Position the chute at the desired starting direction
and set the deflector at the desired angle.
Proper winter footwear is recommended for the
operator to help prevent slipping. Never attempt
to clean snow from excessively steep slopes. The
maximum slope for any operation is 17.7% (10º).
11. Check the speed selector (A, Figure 3) for smooth
operation. The control must move freely into each
speed position gate and remain in position when
released. If the speed selector does not move freely
into all forward and reverse speed positions, contact
your local authorized dealer for assistance.
WARNING
Gasoline is highly flammable and must be
handled with care. Never fill the tank when the
engine is hot or running. Always move outdoors
to fill the tank. Keep snowthrower and gasoline
away from open flame or spark.

CLEARING A CLOGGED DISCHARGE
CHUTE
Hand contact with the rotating auger/impeller inside the
discharge chute is the most common cause of injury
associated with snowthrowers. DO NOT use your hand
to clean out the discharge chute. To clear the chute:
1. Stop the engine. Remove the key.
2. Wait 10 seconds to be sure the auger/impeller blades
have stopped rotating.
3. Always use the clean-out tool. DO NOT use your
hands.
Throttle
Lever
GROUND SPEED SELECTOR
Use the speed selector (A, Figure 7) to control the drive
speed of the snowthrower. There are five forward speeds
and two reverse speeds.
Throttle
Lever
Use the lower speeds to blow deep or wet snow. Use the
higher speeds to blow light snow or to drive the snow-
thrower without blowing snow.
To change speeds, first release the traction drive control
lever (B, Figure 7), then move the speed selector to the
desired speed setting. Fully press the traction drive con-
trol lever to resume operation.
ENGINE SPEED

Operation
DEFLECTOR
Chute
The distance of the discharged snow is mainly controlled
by the position of the deflector (Figure 9). (Engine speed
also affects distance of discharge. Always operate at
FULL throttle.)
Deflector Knob
The more the deflector is tilted UP, the farther snow will
be thrown. Loosen the deflector knob, tilt the deflector
UP or DOWN, and then retighten the knob when the
desired angle has been chosen.

SCRAPER BAR & SKID SHOES
On smooth surfaces such as concrete or asphalt, the
scraper bar should scrape the surface. On surfaces such
as gravel, the scraper bar should be high enough so that
it will not pick up gravel or debris.
The height of the scraper bar is controlled by raising or
lowering the skid shoes (See Figure 10).
1. To raise the scraper bar height, rest the scraper bar
on a strip of wood equal in thickness to the desired
height.

Operation
FREE-WHEELING AND
TRACTION DRIVE LOCK
For easy turning when pushing the snowthrower, you
can disengage the traction drive at one or both wheels
by using the traction lock pins (See Figures 11 & 12).
Klik-Pin In
OUTER Hole
1. Turn the unit off, remove the engine key, and discon-
nect the spark plug wire.
2. To DISENGAGE the traction drive lock, insert the
traction lock pin through the outer hole in the axle.
(See Figure 11).
3. To ENGAGE the traction drive lock, insert the pin
through the hub and axle (See Figure 12). If the hole
in the hub is not aligned with the inner hole in the
axle, push the snowthrower until the holes align and
install the traction lock pin.
NOTE: When snowthrowing with the full width of the
auger, for best drive performance engage both wheels.
For easier turning when not using the full width of the
auger, engage one wheel and use the engaged side as
the snow contact side for the auger.
Figure 11. Traction Drive Lock - Disengaged
AFTER EACH USE
Klik-Pin In
INNER Hole
Normal use of the snowthrower may result in a build-up
of packed snow in and around the starter cord housing
and around engine controls. Heat from the engine will
usually prevent the snow from freezing solid while the
unit is running, but after the engine is shut down, some
snow may continue melting from engine heat, and later
freeze around some moving parts as the unit cools.
After each period of use, follow these steps to prevent
freeze-up caused by ice formation in and around the
engine controls and external parts.
1. Before shutting off the engine, pull the starter rope
out 2 - 3 times, and allow it to rewind slowly. This will
help clear packed snow from the starter cord area.
Allow the engine to run for several minutes.
Figure 12. Traction Drive Lock - Engaged
2. Stop the engine by moving the throttle lever (See
Figure 8) down, or by pulling out the engine key.
WARNING
3. Disconnect the spark plug wire, and position it away
from the spark plug.
Never store snowthrower, with gasoline in engine
or fuel tank, in a heated shelter or in enclosed,
poorly ventilated enclosures. Gasoline fumes may
reach an open flame, spark or pilot light (such as
a furnace, water heater, clothes dryer, etc.) and
cause an explosion.
4. Brush snow and ice from the snowthrower. Be sure to
clear engine and snowthrower controls, discharge
chute, worm and chute rod gears, clutch cable areas,
and anywhere else snow has accumulated.
5. Always remove the engine key and store in a safe
place to prevent unauthorized use.
Handle gasoline carefully. It is highly flammable
and careless use can result in serious fire
damage to people and property.
6. If the snowthrower is kept in a cold shelter, fill the fuel
tank to prevent condensation. Do not store near
sparks or flame.
Drain fuel into an approved container outdoors
away from open flame or sparks.
Note: The engine owner’s manual contains further infor-
mation on preventing ice formation and freeze-up.

WARNING
Do not go near the discharge chute or auger
when the engine is running. Do not run the engine
with any cover or guard removed.

Under most circumstances, if the auger strikes an object
which could cause damage to the unit, the shear pin will
break. (This protects the gear box and other parts from
damage.)

The shear pins are located on the auger shaft as shown
in Figure 32. To replace the shear pins, tap out broken
pin with a pin punch, and install a new shear pin and cot-
ter pin. Spread the legs of the new cotter pin fully. Do
NOT replace shear pins with anything other than the
correct grade replacement shear pin. See the
