the personal safety and/or property of yourself and othe rs. Read and follow all instructions in this manual
before attempting to operate this machine. Failure to comply with these instr uctions 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 op erated according to the rules for safe operat ion 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 proper operation.

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 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.
