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 proper operation. Know how to
stop the machine and disengage them quickly.
3. Never allow children under 14 years of age to operate this machine.
Children 14 and over should read and understand the instructions
and safe operation practices in this manual and on the machine and
be trained and supervised by an adult.
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, 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
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.
1. 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.
2. 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.
3. Use a grounded three-wire extension cord and receptacle for all
machines with electric start engines.
4. Adjust auger housing height to clear gravel or crushed rock surfaces.
5. Disengage all control levers before starting the engine.
6. Never attempt to make any adjustments while engine is running,
except where specifically recommended in the operator’s manual.
7. Let engine and machine adjust to outdoor temperature before
starting to clear snow.
Safe Handling of Gasoline
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.
1. Use only an approved gasoline container.
2. Extinguish all cigarettes, cigars, pipes and other sources of ignition.
3. Never fuel machine indoors.
4. Never remove gas cap or add fuel while the engine is hot or running.
5. Allow engine to cool at least two minutes before refueling.
6. Never over fill fuel tank. Fill tank to no more than ½ inch below bottom
of filler neck to provide space for fuel expansion.
7. Replace gasoline cap and tighten securely.
8. If gasoline is spilled, wipe it off the engine and equipment. Move
machine to another area. Wait 5 minutes before starting the engine. If
fuel is spilled on clothing, change clothing immediately.
9. 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.).
10. Allow machine to cool at least 5 minutes before storing.
11. 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.
12. If possible, 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.
13. Keep the nozzle in contact with the rim of the fuel tank or container
opening at all times until fueling is complete. Do not use a nozzle lock-
open device.
Operation
1. Do not put hands or feet near rotating parts, in the auger housing or
chute assembly. Contact with the rotating parts can amputate hands
and feet.
2. The auger control lever is a safety device. Never bypass its operation.
Doing so makes the machine unsafe and may cause personal injury.
3. The control levers must operate easily in both directions and
automatically return to the disengaged position when released.
4. Never operate with a missing or damaged chute assembly. Keep all
safety devices in place and working.

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.
Keep children away.
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. Do not operate on steep 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.
