Be thoroughly familiar with the controls and the proper use
of the equipment. Know how to stop the unit and
disengage the controls quickly.
Never allow children to operate or play on or near the
equipment. Never allow adults to operate the equipment
without proper instruction.
Keep the area of operation clear of all persons,
particularly small children. Be alert and shut off unit if
children enter area.
Exercise caution to avoid slipping or falling, especially
when operating the snow thrower in reverse.
Always remove key and/or wire from spark plug before
assembly, maintenance or service. Unintentional engine
start up can cause death or serious injury.
Complete a walk-around inspection of the unit to
understand the unit, your work area and all safety decals.
Understand how to operate all controls, the functions of all
controls and how to STOP in an emergency.
Preparation
Always check overhead and side clearances carefully
before operation.
Always be aware of traffic when operating near streets or
along curbs.
Thoroughly inspect the area where the equipment is to be
used and remove all doormats, sleds, boards, toys, wires
and other foreign objects.
Disengage all clutches and shift into neutral before
starting the engine.
Use extension cords and receptacles as specified by the
manufacturer for all units with electric drive motors or
electric starting motors.
Handle fuel with care; it is highly flammable.
• Use an approved fuel container.
• Never add fuel to a running engine or hot engine.
• Fill fuel tank outdoors with extreme care. Never fill fuel
tank indoors.
• 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.
• When practical, 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 refueling is
complete. Do not use a nozzle lock-open device.
• Replace gasoline cap securely and wipe up spilled fuel.
• If fuel is spilled on clothing, change clothing
immediately.
Adjust the auger / impeller housing height to clear gravel
or crushed rock surface.
Never attempt to make any adjustments while the engine
is running (except when specifically recommended by
manufacturer).
Always allow unit and engine to adjust to outdoor
temperature before clearing snow.
Operation
Disengage all controls before starting engine.
Never leave a running unit unattended. Always stop
engine and remove key before leaving unit to prevent
unauthorized use.
Do not put hands or feet near or under rotating parts.
Keep clear of the discharge opening at all times.
Moving and/or rotating parts can cut off body parts such
as fingers or a hand. NEVER place your hands, other
body part or clothing near any moving parts while unit is
running.
Always keep hands away from all pinch points.
Do not touch parts which might be hot from operation.
Allow parts to cool before attempting to maintain, adjust or
service.
Thrown objects can cause injury. Check for weak spots on
docks, ramps or floors. Avoid uneven work areas and
rough terrain and stay alert for hidden hazards.
Exercise extreme caution when operating on or crossing
gravel drives, walks or roads. Stay alert for hidden
hazards or traffic.
EN – 5
After striking a foreign object, stop the engine, remove the
wire from the spark plug, disconnect the cord on electric
motors, thoroughly inspect the snow thrower for any
damage, and repair the damage before restarting and
operating the snow thrower.
If the unit should start to vibrate abnormally, stop the
engine and check immediately for the cause. Vibration is
generally a warning of trouble.
Stop the engine whenever you leave the operating
position, before unclogging the auger / impeller housing or
discharge chute, and when making any repairs,
adjustments or inspections.
When cleaning, repairing or inspecting the snow thrower,
stop the engine and make certain the auger / impeller and
all moving parts have stopped. Disconnect the spark plug
wire and keep the wire away from the plug to prevent
someone from accidentally starting the engine.
Do not run the engine indoors, except when starting the
engine and for transporting the snow thrower in or out of
the building. Open the outside doors; exhaust fumes are
dangerous.
Never operate the snow thrower without proper guards,
and other safety protective devices in place and working.
Always stand clear of the discharge area when operating
this unit.
Never direct the discharge toward people or areas where
injury or property damage can occur from thrown objects.
Keep children and others away.
Do not overload the machine capacity by attempting to
clear snow at too fast a rate.
Never operate the machine at high transport speeds on
slippery surfaces. Look behind and use care when
operating in reverse.
Do not operate in reverse unless absolutely necessary.
Always back up slowly and look down and behind before
and while backing.
Do not carry passengers.
Disengage attachment when not in use and when
traveling from one work area to another.
Disengage power to the auger / impeller when snow
thrower is transported or not in use.
Use only attachments and accessories approved by the
manufacturer of the snow thrower (such as wheel weights,
counterweights or cabs).
This product is equipped with an internal combustion
engine. Do not use unit on or near any unimproved,
forest-covered or brush-covered land unless exhaust
system is equipped with a spark arrester meeting
applicable local, state or federal laws. A spark arrester, if
used, must be maintained in effective working order by
operator.
Never operate the snow thrower without good visibility or
light. Always be sure of your footing, and keep a firm hold
on the handles. Walk; never run.
Never operate unit after or during the use of medication,
drugs or alcohol. Safe operation requires complete and
unimpaired attention at all times.
Never allow anyone to operate this unit when their
alertness or coordination is impaired.
Never touch a hot engine or muffler.
Avoid contact with sharp edges; sharp edges can cut.
Do not throw snow higher than necessary.
Clearing a Clogged Discharge Chute
Hand contact with the rotating auger / impeller inside the
discharge chute is the most common cause of injury
associated with snow throwers. Never use your hand to
clean out the discharge chute.
To clear the chute:
1. SHUT THE ENGINE OFF!
2. Wait 10 seconds to be sure the auger / impeller
blades have stopped rotating.
3. Always use a clean-out tool, not your hands.
Maintenance and Storage
Secure unit so it will not tip over during maintenance.
Before cleaning, removing clogs or making any
inspections, repairs, etc., disengage clutch(es), stop
engine, remove key, allow moving parts to stop and hot
parts to cool.
Check shear bolts and other bolts at frequent intervals for
proper tightness to be sure the equipment is in safe
working condition.
Check clutch and brake operation frequently.
Do not change engine governor settings and do not overspeed engine.
Adjust and service as required. Motion of drive wheels
and auger / impeller must stop quickly when clutch levers
are released.
Always maintain unit in safe operating condition.
Damaged or worn out muffler can cause fire or explosion.
Keep unit free of ice or other debris. Clean up oil or fuel
spills.
Always keep protective structures, guards, and panels in
good repair and secured in place. Never modify or remove
safety devices.
Never store the machine with fuel in the fuel tank inside a
building where ignition sources are present such as hot
water heaters, space heaters or clothes dryers. Close fuel
valve and allow the engine to cool completely before
storing in any enclosure or covering the unit.
Always refer to operator's manual for important details if
the snow thrower is to be stored for an extended period.
EN – 6
Maintain or replace safety and instruction labels as
necessary.
Run the machine a few minutes after throwing snow to
prevent freeze-up of the auger / impeller.
Personal Protection
Do not operate the equipment without wearing adequate
winter garments. Avoid loose fitting clothing that can get
caught in moving parts. Wear footwear that will improve
footing on slippery surfaces.
Wear adequate safety gear, including safety glasses with
side shields and protective gloves.
Do not wear loose clothing or jewelry, and tie back hair
that may get caught in rotating parts.
NEVER attempt to unclog or clean unit while engine is
running. Rotating auger / impeller can cause serious
injury.
Protect eyes, face and head from objects that may be
thrown from unit. Wear appropriate hearing protection.
Always wear safety glasses or eye shields during
operation or while performing an adjustment or repair to
protect eyes from foreign objects that may be thrown from
the machine.
Slope Operation
Exercise extreme caution when operating on slopes. DO
NOT operate on steep slopes. DO NOT clear snow across
the face of slopes; go up and down. Keep all movement
on slopes slow and gradual.
Use a slow speed to avoid stops or shifts on slopes. Avoid
starting or stopping on a slope. Do not park unit on a slope
unless absolutely necessary. When parking on a slope
always block the wheels.
Do not operate near drop-offs, ditches, or embankments.
Unit can suddenly turn over if a wheel is over the edge of
a cliff or ditch, or if an edge caves in.
When practical, remove gas-powered equipment from the
truck or trailer and refuel it on the ground. If this is not
possible, then refuel 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.
If fuel is spilled on clothing, change clothing immediately.
Properly remove fuel before tipping unit up onto housing
to avoid spills.
Towing/Transporting
Always stop engine, remove key and close fuel valve or
drain fuel when transporting unit on a truck or trailer.
Use extra care when loading or unloading unit onto trailer
or truck. Secure unit chassis to transport vehicle. Never
secure from rods or linkages that could be damaged. Do
not transport machine while engine is running.
Accessories
Use only AriensCo-recommended attachments or
accessories that are designed for your unit and that are
appropriate to your use and can be used safely in your
application.
Fuel
DO NOT run engine in an enclosed area. Always provide
good ventilation. Fumes from engine exhaust can cause
injury or death.
Fuel is highly flammable and its vapors are explosive.
Handle with care. Use only an approved gasoline
container with an appropriately-sized dispensing spout.
No smoking, no sparks, no flames. Always allow engine to
cool before servicing.
Never fill fuel tank when engine is running or hot from
operation.
Never fill or drain fuel tank indoors.
Replace fuel cap securely and clean up spilled fuel.
Never fill fuel 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.
