IMPORTANT

Safe Operation Practices for Walk-Behind Snow Throwers

This snow thrower is capable of amputating hands and feet and throwing objects.

Failure to observe the following safety instructions could result in serious injury.

Look for this symbol to point out im­ por tant safety precautions. It means
CAUTION!!! BE COME ALERT!!! YOUR
SAFE TY IS IN VOLVED.

WARNING: Always disconnect spark
plug wire and place it where it can not
con tact plug in order to pre vent ac ci­ den tal start ing when setting up, trans­ port ing, ad just ing or making re pairs.

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, porch es
or other such structures or buildings.

Training

1. Read, understand and follow all instructions on the
machine and in the manual(s) before operating this
unit. Be thoroughly familiar with the controls and the
proper use of the equipment. Know how to stop the
unit and disengage the controls quickly.

2. Never allow children to operate the equipment. Never
allow adults to operate the equipment without proper
instruction.

3. Keep the area of operation clear of all persons, par­ticularly small children.

4. Exercise caution to avoid slipping or falling, especially
when operating the snow thrower in reverse.

Preparation

1. Thoroughly inspect the area where the equipment is
to be used and remove all doormats, sleds, boards,
wires, and other foreign objects.

2. Disengage all clutches and shift into neutral before
starting the engine (motor).

3. 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.

4. Handle fuel with care; it is highly flammable
(a) Use an approved fuel container.
(b) Never add fuel to a running engine or hot engine.
(c) Fill fuel tank outdoors with extreme care. Never fill

fuel tank indoors.

(d) 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.

(e) 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.

WARNING: Snow throwers have ex­ posed rotating parts, which can cause
severe injury from contact, or from ma­terial 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 con stit u ents, and certain vehicle
com po nents contain or emit chem i­cals known to the State of Cal i for nia
to cause can cer and birth defects or
oth er re pro duc tive harm.

(f) 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.

(g) Replace gasoline cap securely and wipe up spilled

fuel.

(h) If fuel is spilled on clothing, change clothing im-

mediately.

5. Use extension cords and receptacles as specified by
the manufacturer for all units with electric drive motors
or electric starting motors.

6. Adjust the collector housing height to clear gravel or
crushed rock surface.

7. Never attempt to make any adjustments while the
engine (motor) is running (except when specifically
recommended by manufacturer).

8. 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.

9. Use ear protectors to avoid damage to hearing.

Operation

1. Do not put hands or feet near or under rotating parts.
Keep clear of the discharge opening at all times.

2. Exercise extreme caution when operating on or cross­ing gravel drives, walks, or roads. Stay alert for hidden
hazards or traffic.

3. After striking a foreign object, stop the engine (motor),
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.

4. If the unit should start to vibrate abnormally, stop the
engine (motor) and check immediately for the cause.
Vibration is generally a warning of trouble.

5. Stop the engine (motor) whenever you leave the oper­ating position, before unclogging the collector/impeller
housing or discharge chute, and when making any
repairs, adjustments or inspections.

2

6. When cleaning, repairing or inspecting the snow
thrower, stop the engine and make certain the collector/
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.

7. 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.

8. Exercise extreme caution when operating on slopes.

9. Never operate the snow thrower without proper guards,
and other safety protective devices in place and working.

10. Never direct the discharge toward people or areas
where property damage can occur. Keep children and
others away.

11. Do not overload the machine capacity by attempting
to clear snow at too fast a rate.

12. Never operate the machine at high transport speeds
on slippery surfaces. Look behind and use care when
operating in reverse.

13. Disengage power to the collector/impeller when snow
thrower is transported or not in use.

14. Use only attachments and accessories approved by
the manufacturer of the snow thrower (such as wheel
weights, counterweights, or cabs).

15. 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.

16. Never touch a hot engine or muffler.

17. When using your snowthrower for long periods of time
in deep snow, be aware of snow and ice build up be­tween the track components. This may cause a loss
of performance in the drive system.

Clean out snow and debris between tracks in regular
intervals.

Clearing a Clogged Discharge Chute

Hand contact with the rotating 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 impeller blades have
stopped rotating.

3. Always use a clean-out tool, not your hands.

Maintenance and Storage

1. Check shear bolts and other bolts at frequent intervals
for proper tightness to be sure the equipment is in safe
working condition.

2. 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.
Allow the engine to cool before storing in any enclosure.

3. Always refer to operator’s manual for important details
if the snow thrower is to be stored for an extended
period.

4. Maintain or replace safety and instruction labels, as
necessary.

5. Run the machine a few minutes after throwing snow
to prevent freeze-up of the collector/impeller.
