SAFE OPERATION PRACTICES
WARNING: This symbol points out important safety instructions which, if not followed, could endanger
the personal safety and/or property of yourself and others. Read and follow all instructions in this manual
before attempting to operate this machine. Failure to comply with these instructions may result in personal
injury. When you see this symbol—heed its warning.
WARNING: Engine Exhaust, some of its constituents, and certain vehicle components contain
or emit chemicals known to State of California to cause cancer and birth defects or other
reproductive harm.
DANGER: This machine 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. This
machine is capable of amputating hands and feet and throwing objects. Failure to observe the following safety
instructions could result in serious injury or death.
Training
1. Read, understand, and follow all instructions on the
machine and in the manual(s) before attempting to
assemble and operate. Keep this manual in a safe place
for future and regular reference and for ordering
replacement parts.
2. Be familiar with all controls and their operation. Know
how to stop the machine and disengage controls.
3. Never allow children under 14 years old to operate this
machine. Children 14 years old and over should read and
understand the operation instructions and safety rules in
this manual and should be trained and supervised by a
parent.
4. Never allow adults to operate this machine without
proper instruction.
5. Thrown objects can cause serious personal injury. Plan
your snow-throwing pattern to avoid discharge of material
toward roads, bystanders and the like.
6. Keep bystanders, helpers, pets and children at least 75
feet from the machine while it is in operation. Stop
machine if anyone enters the area.
7. Exercise caution to avoid slipping or falling, especially
when operating in reverse.
Preparation
1. Thoroughly inspect the area where the equipment is to
be used. Remove all doormats, newspapers, sleds,
boards, wires and other foreign objects, which could be
tripped over or thrown by the auger/impeller.
2. Always wear safety glasses or eye shields during
operation and while performing an adjustment or repair to
protect your eyes. Thrown objects which ricochet can
cause serious injury to the eyes.
3. Do not operate without wearing adequate winter outer
garments. Do not wear jewelry, long scarves or other
loose clothing, which could become entangled in moving
parts. Wear footwear which will improve footing on
slippery surfaces.
4. Use a grounded three-wire extension cord and
receptacle for all units with electric start engines.
5. Adjust collector housing height to clear gravel or crushed
rock surfaces.
6. Disengage all clutch levers before starting the engine.
7. Never attempt to make any adjustments while engine is
running, except where specifically recommended in the
operator’s manual.
8. Let engine and machine adjust to outdoor temperature
before starting to clear snow.
9. To avoid personal injury or property damage use extreme
care in handling gasoline. Gasoline is extremely
flammable and the vapors are explosive. Serious
personal injury can occur when gasoline is spilled on
yourself or your clothes, which can ignite. Wash your skin
and change clothes immediately.
a. Use only an approved gasoline container.
b. Extinguish all cigarettes, cigars, pipes and other
sources of ignition.
c. Never fuel machine indoors.
d. Never remove gas cap or add fuel while the
engine is hot or running.
e. Allow engine to cool at least two minutes before
refueling.
f. Never over fill fuel tank. Fill tank to no more than
½ inch below bottom of filler neck to provide space
for fuel expansion.
g. Replace gasoline cap and tighten securely.
h. If gasoline is spilled, wipe it off the engine and
equipment. Move machine to another area. Wait 5
minutes before starting the engine.
i. Never store the machine or fuel container inside
where there is an open flame, spark or pilot light
(e.g. furnace, water heater, space heater, clothes
dryer etc.).
j. Allow unit to cool for 5 minutes before storing.
Operation
1. Do not put hands or feet near rotating parts, in the auger/
impeller housing or discharge chute. Contact with the
rotating parts can amputate hands and feet.
2. The auger/impeller clutch lever is a safety device. Never
bypass its operation. Doing so makes the machine
unsafe and may cause personal injury.
3. The clutch levers must operate easily in both directions
and automatically return to the disengaged position when
released.
4. Never operate with a missing or damaged discharge
chute. Keep all safety devices in place and working.
5. Never run an engine indoors or in a poorly ventilated
3
area. Engine exhaust contains carbon monoxide, an
odorless and deadly gas.
6. Do not operate machine while under the influence of
alcohol or drugs.
7. Muffler and engine become hot and can cause a burn. Do
not touch.
8. Exercise extreme caution when operating on or crossing
gravel surfaces. Stay alert for hidden hazards or traffic.
9. Exercise caution when changing direction and while
operating on slopes.
10. Plan your snow-throwing pattern to avoid discharge
towards windows, walls, cars etc. Thus, avoiding
possible property damage or personal injury caused by a
ricochet.
11. Never direct discharge at children, bystanders and pets
or allow anyone in front of the machine.
12. Do not overload machine capacity by attempting to clear
snow at too fast of a rate.
13. Never operate this machine without good visibility or
light. Always be sure of your footing and keep a firm hold
on the handles. Walk, never run.
14. Disengage power to the auger/impeller when
transporting or not in use.
15. Never operate machine at high transport speeds on
slippery surfaces. Look down and behind and use care
when in reverse.
16. If the machine should start to vibrate abnormally, stop the
engine, disconnect the spark plug wire and ground it
against the engine. Inspect thoroughly for damage.
Repair any damage before starting and operating.
17. Disengage all clutch levers and stop engine before you
leave the operating position (behind the handles). Wait
until the auger/impeller comes to a complete stop before
unclogging the discharge chute, making any
adjustments, or inspections.
18. Never put your hand in the discharge or collector
openings. Always use the clean-out tool provided to
unclog the discharge opening. Do not unclog discharge
chute while engine is running. Before unclogging, shut off
engine and remain behind handles until all moving parts
have stopped completely.
19. Use only attachments and accessories approved by the
manufacturer (e.g. wheel weights, tire chains, cabs etc.).
20. If situations occur which are not covered in this manual,
use care and good judgment. Contact Sears service
center for assistance.
Maintenance & Storage
1. Never tamper with safety devices. Check their proper

• Tip the snow thrower forward so that it rests on the
auger housing.
• Move the shift lever all the way forward to the sixth
(6) position.
• With the traction drive lever released, spin the snow
thrower wheels by hand. The wheels should turn;
however, you may feel some resistance.
• Engage the traction drive clutch grip. The wheels
should no longer turn.
• Now release the traction drive clutch grip, and spin
the wheels again.
• Move the shift lever back to the fast reverse
position, then all the way forward again. There
should be no resistance in the shift lever, and the
wheels should turn.
10
• If you face resistance when moving the shift lever
or the snow thrower wheels stop when they should
not, loosen the lock nut on the traction drive cable
and unthread the cable one turn.
• If the wheels can still be turned when you engage
the traction drive clutch grip, loosen the lock nut on
the traction drive cable and thread the cable in one
turn.

necessary. Tighten the jam nut to secure the cable
when correct adjustment is reached.
NOTE: If you are not sure that you have reached
correct adjustment, refer to the Adjustment section on
page 20.
Skid Shoe
The space between the shave plate and the ground
can be adjusted. For close snow removal, place skid
shoes in the low position. Use middle or high position
when area to be cleared is uneven.
NOTE: It is not recommended that you operate this
snow thrower on gravel as loose gravel can be easily
picked up and thrown by the auger causing an injury or
damage to the snow thrower.
• If for some reason, you have to operate the snow
thrower on gravel, keep the skid shoe in the highest
position for maximum clearance between the
ground and the shave plate.
• Adjust skid shoes by loosening the four hex nuts
and carriage bolts and moving skid shoes to
desired position.
• Make certain the entire bottom surface of skid shoe
is against the ground to avoid uneven wear on the
skid shoes.
