SECTION1: IMPORTANT
SAFEOPERATION
PRACTICES
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,
contain or emit chemicals known to the State of California
other reproductive

and certain vehicle components
to cause cancer, birth defects or

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.

4.
5.

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.
Be familiar with all controls and their proper operation.
Know how to stop the machine and disengage them
quickly.
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.
Never allow adults to operate this machine without
proper instruction.
Thrown objects can cause serious personal injury. Plan
your snow-throwing pattern to avoid discharge of material
toward roads, bystanders and the like.
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.
Exercise caution to avoid slipping or falling, especially
when operating in reverse.

PREPARATION
1.

4.
5.
6.

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.
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.
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.
Use a grounded three-wire extension cord and
receptacle for all units with electric start engines.
Adjust collector housing height to clear gravel or crushed
rock surfaces.
Disengage all clutch levers before starting the engine.

Never attempt to make any adjustments while engine is
running, except where specifically recommended in the
operator's manual.
Let engine and machine adjust to outdoor temperature
before starting to clear snow.
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 fitt 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 machine to cool at least 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.
The auger/impeller clutch lever is a safety device. Never
bypass its operation. Doing so makes the machine
unsafe and may cause personal injury.
The clutch levers must operate easily in both directions
and automatically return to the disengaged position when
released.
