TRAINING
• Read the operating and service instruction manual
carefully. 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 the equipment. Never
allow adults to operate the equipment without proper
instruction.
• Keep the area of operation clear of all persons, par-
ticularly small children and pets.
• Exercise caution to avoid slipping or falling especially
when operating in reverse.
PREPARATION
• Remove foreign objects. Thoroughly inspect the area
where the equipment is to be used and remove all
doormats, sleds, boards, wires, rocks & landscaping.
• Disengage all clutches before starting engine (mo-
tor).
CAUTION!!! BECOME ALERT!!! YOUR
SAFETY IS INVOLVED.
WARNING: Always disconnect spark
plug wire and place it where it cannot
contact plug in order to prevent acci-
dental starting when setting up, trans-
porting, adjusting or making repairs.
WARNING: This snow thrower is for
use on sidewalks, driveways and other
ground level surfaces. Caution should
be exercised while using on sloping
surfaces. Do not use snow thrower on
surfaces above ground level such as
roofs of residences, garages, porches
or other such structures or buildings.
WARNING: Snow throwers have ex-
posed rotating parts, which can cause
severe injury from contact, or from ma-
terial thrown from the discharge chute.
Keep the area of operation clear of all
persons, small children and pets at all
times including startup.
CAUTION: Muffler and other engine
parts become extremely hot during
operation and remain hot after engine
has stopped.To avoid severe burns on
contact, stay away from these areas.
WARNING: Engine exhaust, some of
its constituents, and certain vehicle
components contain or emit chemi-
cals known to the State of California
to cause cancer and birth defects or
other reproductive harm.
Safe Operation Practices for Snow Throwers
Do not operate the equipment without wearing ade-
quate winter outer garments. Avoid loose, dangling
clothing, such as scarves, which can get caught in
rotating parts. Wear footwear that will improve footing
on slippery surfaces.
Handle fuel with care; it is highly flammable.
Never smoke while refueling.
Use an approved fuel container.
Never remove fuel tank cap or add fuel to a running
engine (motor) or hot engine (motor).
Fill fuel tank outdoors with extreme care. Never fill
fuel tank indoors.
Replace fuel cap securely and wipe up spilled
fuel.
Never store fuel or snow thrower with fuel in the
tank inside of a building where fumes may reach
an open flame or spark.
Check fuel supply before each use, allowing space
for expansion as the heat of the engine (motor)
and/or sun cause fuel to expand.
STATIC ELECTRICITY HAZARD -
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
tankopening atall times, until refueling iscomplete.
Do not use a nozzle lock-open device.
If fuel is spilled on clothing, change clothing im-
mediately.
For all units with electric starting motors use electric
starting extension cords certified CSA/UL. Use only
with a receptacle that has been installed in accordance
with local inspection authorities.
If snow thrower must be operated over gravel surface,
use extra caution and be sure skid plates are adjusted
to lowest (highest scraper clearance) position.
Never attempt to make any adjustments while the
engine (motor) is running (except when specifically
recommended by manufacturer).
Let engine (motor) and snow thrower adjust to outdoor
temperatures before starting to clear snow.
Always wear safety glasses or eye shields during op-
eration or while performing an adjustment or repair to
protect eyes from foreign objects that may be thrown
from the snow thrower.

• Do not clear snow across the face of slopes. Exercise
extreme caution when changing direction on slopes.
Do not attempt to clear steep slopes.
• Never operate the snow thrower without proper guards,
plates or other safety protective devices in place.
• Never operate the snow thrower near glass enclo-
sures, automobiles, window wells, drop-offs, and the
like without proper adjustment of the snow discharge
angle. Keep children and pets 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
backing up.
• Never direct discharge at bystanders or allow anyone
in front of the unit.
• 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, cabs, tire chains, electric start
kits, etc.).
• 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.
• Do not overreach. Keep proper footing and balance at
all times.
• This snow thrower is for use on sidewalks, driveways
and other ground level surfaces.
• Do not use the snow thrower on surfaces above ground
level such as roofs of residences, garages, porches or
other such structures or buildings.
MAINTENANCE AND STORAGE
• Check shear bolts and other bolts at frequent intervals
for proper tightness to be sure the equipment is in safe
working condition.
• Never store the snow thrower with fuel inthetankinside
a building where ignition sources are present such as
hot water and space heaters, clothes dryers, and the
like. Allow the engine (motor) to cool before storing in
any enclosure.
• Always refer to operator's guide instructions for im-
portant details if the snow thrower is to be stored for
an extended period.
• Maintain or replace safety and instruction labels, as
necessary.
• Run the snow thrower, with auger engaged, a few
minutes after throwing snow to clear the machine and
prevent freeze-up of the auger/impeller.
