Safe Operation Practices for Walk-Behind Snow Throwers
This snow thrower is capable of amputating hands and feet and throwing objects. Failure to
observe the following safety instructions could result in serious injury.
Training
1. Read, understand, and follow all instructions on the machine and in the manual(s) before
attempting to assemble and operate this unit. 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 proper operation. Know how to stop the machine and
disengage them quickly.
3. Never allow children under 14 years old to operate this machine. Children 14 years old and over
should read and understand the operation instruction and safety rules in this manual and should
be trained and supervised by 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.

clothing that can get caught in moving parts. 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 clutches and shift into neutral 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 handing 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. Fill fuel tank outdoors with extreme care. Never fill fuel tank 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 1/2 inch below bottom of filler neck to
provide space for fuel expansion.
g. Never fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always
place containers on the ground, away from your vehicle, before filling.
h. 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 equipment on a trailer with a portable
container, rather than from a gasoline dispenser nozzle.
i. Keep the 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.
j. Replace gasoline cap and tighten securely.
k. If gasoline is spilled, wipe it off the engine and equipment. Move machine to another area.
Wait 5minutes before starting the engine.
l. 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,)
m. Allow machine to cool at least 5 minutes before storing.
n. If fuel is spilled on clothing, change clothing immediately.
Operation
1. Do not put hands or feet near rotating parts, in the auger/impeller housing or chute assembly.
Contact with the rotating parts can amputate hands and feet. Keep clear of the discharge
opening at all times.
2. After striking a foreign object, stop the engine (motor), remove the wire from the spark plug,
disconnect the cord on electric motors, thoroughly inspect the snow thrower for any damage,
and repair the damage before restarting and operating the snow thrower.
3. Stop the engine (motor) whenever you leave the operating position, before unclogging the
collector/impeller housing or discharge chute, and when making any repairs, adjustments or
inspections.
4. When cleaning, repairing or inspecting the snow thrower, stop the engine and make certain the
collector/impeller and all moving parts have stopped. Disconnect the spark plug wire and keep
the wire away from the plug to prevent someone from accidentally starting the engine
5. The auger/impeller control lever is a safety device. Never bypass its operation. Doing so
makes the machine unsafe and may cause personal injury.
6. The control levers must operate easily in both directions and automatically return to the
disengaged position when released.
7. Never operate the snow thrower without proper guards, and other safety protective devices in
place and working.
8. Never run an engine indoors or in a poorly ventilated area. Engine exhaust contains carbon
monoxide, an odorless and deadly gas.
SAFE OPERATION PRACTICES

9. Do not operate machine while under the influence of alcohol or drugs.
10. Exercise extreme caution when operating on or crossing gravel surfaces. Stay alert for hidden
hazards or traffic.
11. Exercise caution when changing direction and while operating on slopes.
12. 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.
13. Never direct the discharge toward people or areas where property damage can occur. Keep
children and others away.
14. Do not overload machine capacity by attempting to clear snow at too fast of a rate.
15. 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.
16. Disengage power to the auger/impeller when transporting or not in use.
17. Never operate machine at high transport speeds on slippery surfaces. Look down and behind
and use care when backing up.
18. If the machines 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.
19. Disengage all control 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
chute assembly, making any adjustments, or inspections.
20. 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 chute assembly while engine is
running. Shut off engine and remain behind handles until all moving parts have stopped before
unclogging.
21. Use only attachments and accessories approved by the manufacturer (e.g. wheel weights, tire
chins, cabs etc.).
22. Never touch a hot engine or muffler
23. If situations occur which are not covered in this manual, use care and good judgment. Contact
your Sears Service Center for assistance.
Clearing a Clogged Discharge Chute
Hand contact with the rotating impeller inside the discharge chute is the most common cause of
injury associated with snow throwers. Never use your hand to clean out the discharge chute.
To clear the chute:
1. SHUT THE ENGINE OFF!
2. Wait 10 seconds to be sure the impeller blades have stopped rotating.
3. Always use a clean-out tool, not your hands
Maintenance & Storage
1. Never tamper with safety devices. Check their proper operation regularly. Refer to the
maintenance and adjustment sections of this manual.
2. Before cleaning, repairing, or inspecting machine disengage all control levers and stop the
