with the instructions may result in personal injury.
SAFE OPERATION PRACTICES FOR SNOW THROWERS
TRAINING
1. Read this Owner’s manual carefully. Be thoroughly
familiar with the controls and proper use of the
equipment. Know how to stop the unit and dis
engage the controls quickly.
2. Never allow children to operate equipment. Never
allow adults to operate equipment without proper
instructions.
3. No one should operate this unit while intoxicated or
while taking medication that impairs the senses or
reactions.
4. Keep the area of operation clear of all persons,
especially small children and pets.
5. Exercise caution to avoid slipping or falling, espe
cially when operating in reverse.
PREPARATION
1. Thoroughly inspect the area where the equipment is
to be used and remove all door mats, sleds, boards,
wires and other foreign objects.
2. Disengage all clutches and shift into neutral before
starting engine.
3. Do not operate equipment without wearing ade
quate winter outer garments. Wear footwear which
will improve footing on slippery surfaces.
4. Handle fuel with care. It is highly flammable.
(A) Use approved fuel container.
(B) Never add fuel to a running engine or hot
engine.
(C) Fill fuel tank outdoors with extreme care. Never
fill fuel tank indoors.
(D) Replace gasoline cap securely and wipe up
spilled fuel.
5. Use a grounded three wire plug-in for all units with
electric drive motors or electric starting motors.
6. Adjust collector housing height to clear gravel or
crushed rock surface.
7. Never attempt to make any adjustments while
engine is running (except where specifically recom
mended by manufacturer).
8. Let engine and machine adjust to outdoor tem
perature before starting to clear snow.
OPERATION
1. Do not put hands or feet near rotating parts. Keep
clear of discharge opening at all times.
2. Exercise extreme caution when operating on or
crossing gravel drives, walks, or roads. Stay alert for
hidden hazards or traffic. Do not carry passengers.
3. After striking a foreign object, stop the engine,
remove wire from spark plug, and thoroughly in
spect the snow thrower for any damage. Repair the
damage before restarting and operating the snow
thrower.
4. If the snow thrower should start to vibrate abnormal
ly, stop the engine and check immediately for the
cause. Vibration is generally a warning of trouble.
5. Stop engine whenever you leave the operating posi
tion, before unclogging the collector/impeller hous
ing or discharge guide, and making any repairs, ad
justments, or inspections.
6. Take all possible precautions when leaving the vehi
cle unattended. Disengage the power take-off, lower
the attachment, shift into neutral, set the parking
brake, stop the engine, and remove the key.
7. When cleaning, repairing, or inspecting, make cer
tain collector/impeller and all moving parts have
stopped. Disconnect spark plug wire and keep away
from plug to prevent accidental starting.
8. Do not run engine indoors, except when starting
engine and transporting snow thrower in or out of
building. Open doors. Exhaust fumes are dan
gerous.
9. Do not clear snow across the face of slopes. Exer
cise extreme caution when changing direction on
slopes. Do not attempt to clear steep slopes.
10. Never operate snow thrower without guards, plates,
or other safety protection devices in place.
11. Never operate snow thrower near glass enclosure,
automobiles, window wells, drop off, etc., without
proper adjustments of s iow thrower discharge
angle. Keep children and p ¡ts away.
12. Do not overload machine c< r acity by attempting to
clear snow at too fast a rate
13. Never operate machine at h
slippery surfaces. Use care
14. Never direct discharge a
anyone in iron. ^nit.
15. Disengage power to collector/impeller when
transporting or not in use.
16. Use only attachments and accessories approved by
the manufacturer of snow thrower (such as wheel
weights, counter weights, cabs, etc.).
17. 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.
MAINTENANCE AND STORAGE
1. Check shear bolts, engine mounting bolts, etc., at
frequent intervals for proper tightness to be sure
equipment is in safe working condition.
2. Never store machine with fuel in the fuel tank inside
a building where open flame or spark are present.
Allow engine to cool before storing in any
enclosure.
3. Always refer to owner’s guide instructions for im
portant details if snow thrower is to be stored for an
extended period.
4. Run machine a few minutes after throwing snow to
prevent freeze up of collector/impeller.

rods are as follows; The left hand lockout rod
for the drive clutch should have approximately
IV2 inches of thread showing below the nut.
The right hand lockout rod for the auger
clutch should have approximately Va inch of
thread showing below the nut. See figure 14.
FINAL ADJUSTMENT MUST BE MADE AS
DESCRIBED IN STEPS 21 AND 22. If the left
hand lockout rod is not adjusted correctly, the
shift lever cannot be shifted past neutral. If
the right hand lockout rod is not adjusted cor
rectly, the augers will not stop rotating.

Shift Lever (See figures 18 and 19)
The shift lever is located on the left hand side of
handle panel. The shift lever may be moved into
one of eight positions. Run engine with throttle in
the fast position. Use the shift lever to determine
ground speed.
a. Center position (N)—“NEUTRAL."

speeds. Position number one (1) is the slowest.
Position number five (5) is the fastest.
FIGURE 18.
c. Rear position—Two reverse (R) speeds. “R”
nearest the neutral (N) position is the slower of
the two.
FIGURE 19.
Throttle Control (See figures 18 and 20)
The throttle control is located on the righ hand
side of the handle panel. It regulates the speed of
the engine.
Drive Clutch (See figure 18)
The drive clutch is located on the left handle.
Squeeze the clutch grip to engage drive. Release
to stop.
Auger Clutch (See figure 18)
The auger clutch is located on the right handle.
Squeeze the clutch grip to engage the cugers.
Release to stop the snow throwing action.
Chute Crank (See figure 18)
The chute crank is located on left hand side of the
snow thrower.
To change the direction in which snow is th rown,
turn chute crank as follows:
1. Crank clockwise to discharge to the left.
2. Crank counterclockwise to discharge o the
right.
Safety Ignition Switch (See figure 21)
The ignition key must be inserted in the s witch
before the unit wili start. Remove the ignition key
when snow thrower is not in use.
