• Keep bystanders, 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
Thoroughly inspect the area where the equipment is to be used. Remove all doormats, newspapers, sleds,
boards, wires, branches and other foreign objects, which could be hazardous and damage the auger
system.
• Always wear safety glasses or eye shields during operation and while performing an adjustment or
repair to protect your eyes, as thrown objects can ricochet and 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, and wear footwear that will
improve footing on slippery surfaces.
• Use a grounded “three-wire” extension cord and receptacle for all machines with electric start
engines.
• Adjust skid shoe and/or housing height to clear gravel or crushed rock surfaces.
• Disengage all control levers before starting the engine.
• Never attempt to make any adjustments while engine is running, except where specifically
recommended in the instruction manual.
• Let engine and machine adjust to outdoor temperature before starting to clear snow.
6
PERSONAL SAFETY
• Engine exhaust, and certain vehicle components contain or emit chemicals known to cause cancer,
birth defects or other reproductive harm.
• Read, understand and follow all instructions on your snow thrower unit and in this instruction manual
before attempting to assemble and operate your machine.
• Keep this instruction manual in a safe place for future and regular reference. If replacement parts are
needed, refer to the Panel, Chute, Frame and Housing Diagrams and Parts’ Listings on pages 25-30.
• Stay alert, watch what you are doing and use common sense when operating your snow thrower unit.
• Do not use your snow thrower unit while you are tired or under the influence of drugs, alcohol,
medication. A moment of inattention while operating the snow thrower may result in severe bodily
injury.
• NEVER LEAVE YOUR RUNNING SNOW THROWER UNATTENDED. Stop the engine!
• Do not leave your snow thrower unit until it has come to a complete stop.
• When stepping backwards, be cautious about any obstacles beneath your feet or behind you avoid
falling.
SERVICE
• Stop the engine before making any adjustments. Check for misalignment, breakage or binding of
moving parts, and any other conditions that may affect operation.

manufactured replacement parts. This will ensure that the safety of the snow thrower unit is
maintained.
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, therefore wash your skin and change clothes
immediately.
• Use only an approved gasoline container.
• Extinguish all cigarettes, cigars, pipes and other sources of ignition.
• Never fuel snow thrower unit’s engine indoors.
• Never remove gas cap or add fuel while the engine is hot or running.
• Allow engine to cool at least two minutes before refueling.
7
• Never over fill fuel tank.
• Replace gasoline cap and tighten securely.
• If gasoline is spilled, wipe it off the engine and equipment. Move machine to another area. Wait 5
minutes before starting the engine.
• Never store the machine or fuel container inside where there is an open flame, spark or pilot light (e.g.
furnace, water heats, space heater, clothes dryer etc.).
• Allow machine to cool at least 5 minutes before storing.
• 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.
• 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.
• 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
• 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.
• The auger (impeller) control lever is a safety device. Never bypass its operation. Doing so makes the
machine unsafe and may cause personal injury.
• The control levers must operate easily in both directions and automatically return to the disengaged
(vertical) position when released.
• Never operate with a missing or damaged chute assembly. Keep all safety devices in place and
working.
• Never run an engine indoors or in a poorly ventilated area. Engine exhaust contains carbon monoxide,
an odorless and deadly gas.
• Do not operate machine while under the influence of alcohol or drugs.
• Muffler and engine become hot and can cause burning. Do not touch. Keep children away.
• Exercise extreme caution when operating on or crossing gravel surfaces. Stay alert for hidden hazards
or traffic.
• Exercise caution when changing direction and while operating on slopes.
8
• Plan your snow-throwing pattern to avoid snow discharge towards windows, walls, cars etc., thus
avoiding possible property damage or personal injury caused by a ricocheting debris.
• Never direct discharge at children, bystanders and pets or allow anyone in front of the machine.
• Do not overload machine capacity by attempting to clear snow at too fast of a rate…. Remember!
Slow and steady operation is best to avoid clogs of snow being impelled too rapidly.
• 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.
• Disengage power to the auger system (auger/impeller) by releasing the auger control (lever) when
transporting or not in use.
• Never operate machine at high transport speeds on slippery surfaces. Look down and behind and use
care when backing up.
• If the machine 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.
• Disengage all (drive and auger) control levers and stop engine before you leave the operation position
(behind the handles).
• Wait until the auger /impeller comes to a complete stop before unclogging the chute assembly,
making any adjustments or inspections.
• 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.
• Use only attachments and accessories approved by the manufacturer (e.g. wheel weights, tire chains,
cabs etc.).
• When staring engine, pull cord slowly until resistance is felt, then pull rapidly, Rapid retraction of
starter cord (kickback) will pull hand and arm toward engine faster then you can let go. B roken bones,
fractures, bruises or sprains could result.
• If situations occur which are not covered in this manual, use care and good judgment contact
customer support for assistance.
MAINTENANCE & STORAGE
• Never tamper with safety devices. Check their proper operation regularly. Refer to the maintenance
and adjustment sections of manual.
• Before cleaning, repairing, or inspecting machine disengage all control levers and stop the engine.
• Wait until the auger impeller comes to a complete stop. Disconnect the spark plug wire to prevent
unintended starting.
9
• Check bolts and screws for proper tightness (EVERYTIME before & after use) as engine vibration
could cause hardware to loosen…consider using a Loc-Tite product to keep hardware secure.
This process will keep the machine in safe working condition. Also, visually inspect machine for any
damage.
• Verify that the auger gearbox, located between your right and left auger blades, has substantial
lubricant in the casing.
The gearbox fill and drain plugs (bolts) are the only “vertical” plugs (bolts) on the gearbox assembly
when viewed in the standing position. The top plug (bolt) is used for filling…the bottom plug (bolt) is
for draining. Simply remove the top plug (bolt) for verification of lubricant, as it should be inside. To
drain, simply remove bottom plug (bolt).
• Do not change the engine governor setting or overspeed the engine. The governor controls the
maximum safe operating speed of the engine.
• Snow thrower auger belts, shave plates, shear pins and skid shoes are subject to wear and
damage, therefore it is expected that the owner assume personal responsibility for the
maintenance (removal & installation) of these items.
• For your safety protection, frequently check all components and replace with original equipment
manufacturers (OEM) parts only. Use of parts which do not meet the original equipment
specifications may lead to improper performance and compromise safety.
• Check (d riv e & au ger) control lever (handles) and cables periodically to verify they engage and
disengage properly and adjust, if necessary. Refer to the adjustment section in this operator's manual
for instructions.
• Maintain or replace safety and instruction labels, as necessary.
• Observe proper disposal laws and regulations for gas, oil, etc. to protect the environment.
• Prior to storing, run machine a few minutes to clear snow from machine and prevent freeze up of
auger impeller and completely wipe down unit, while inspecting for frozen components.
• Never store the machine or fuel container inside where there is an open flame, spark or pilot light
such as water heater, furnace, clothes dryer etc.
• Always refer to the operator's manual for proper instructions on off-season storage. A YouTube video
is available, which illustrates this process:
https://www.youtube.com/watch?v=X4KYcFEfeY4
• Check fuel line, tank, cap and fittings frequently for cracks or leaks. Replace if necessary.
• Do not crank engine with spark plug removed.
• Have the machine inspected annually by an authorized service dealer to ensure that all mechanical
and safety systems are working properly and have not worn excessively*. Failure to do so can result
in accidents, injuries or death.
*Please note that an annual inspection is not covered within the warranty program…only
REPAIR service.
DO NOT MODIFY THE ENGINE
To avoid serious injury or death, do not modify engine in any way. Tampering with the governor setting
can lead to a runaway engine and cause it to operate at unsafe speeds. Never tamper with factory
setting of engine governor.
