SECTION 1: IMPORTANT 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 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 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 door mats, 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. Throw n 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 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.
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
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. To avoid 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.

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 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 a clearing tool to unclog the
discharge opening.
19. Use only attachments and accessories approved by the
manufacturer (e.g. wheel weights, tire chai ns, cabs etc.).
20. If situations occur which are not covered in this manual,
use care and good judgment. Contact your dealer or
telephone 1-800-800-7310 for assistance and the name
of your nearest servicing dealer.
Maintenance And Storage
1. Never tamper with safety devices. Check their proper
operation regularly.
2. Disengage all clutch levers and stop engine. Wait until

inspecting.
3. Check bolts, and screws for proper tightness at frequent
intervals to keep the machine in safe working condition.
Also, visually inspect machine for any damage.

wear and damage. For your safety protection, frequently
check all components and replace with original
equipment manufacturer’s (O.E.M.) parts only. “Use of
parts which do not meet the original equipment
specifications may lead to improper performance and
compromise safety!”

and disengage properly and adjust, if necessary. Refer to
the adjustment section in this operator’s manual for
instructions.
7. Maintain or replace safety and instruction labels, as
necessary.

oil, etc. to protect the environment.
9. Prior to storing, run machine a few minutes to clear snow
from machine and prevent freeze up of auger/impeller.
10. Never store the machine or fuel container inside where
there is an open flame, spark or pilot light such as a water
heater, furnace, clothes dryer etc.
11. Always refer to the operator’s manual for proper
instructions on off-season storage.
