SAFETY PRECAUTIONS
Careful operation is your best insurance against an accident. Read this section carefully before operating the tractor
and snowblower. This snowblower is capable of amputating hands and feet and throwing objects. Failure to observe
the following safety instructions could result in serious injury. All operators, no matter how experienced they may be,
should read this and other manuals related to the tractor and snowblower before operating. It is the owner's legal
obligation to instruct all operators in safe operation of the snowblower.
TRAINING
This symbol, "Safety Alert Symbol", is used
throughout this manual and on the
snowblower’s safety labels to warn of the
possibility of serious injuries. Please take
special care in reading and understanding the
safety precautions before operating the
snowblower or the tractor.
1. Read this owner's manual carefully. Be thoroughly
familiar with the controls and proper use of the
tractor and snowblower. Know how to stop the unit
and disengage the controls quickly.
2. Never allow children to operate snowblower nor the
tractor. Never allow adults to operate snowblower
nor the tractor without proper instructions.
3. No one should operate the tractor nor the
snowblower while intoxicated or while taking
medication that impairs the senses or reactions.
4. Keep the area of operation clear of all persons,
particularly small children and pets.
PREPARATION
1. Thoroughly inspect the area where the snowblower
is to be used and remove door mats, all foreign
objects and the like.
2. Disengage all clutches and shift into neutral before
starting engine.
3. Do not operate the snowblower without wearing
adequate winter outer 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 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 a 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.
f) Keep the nozzle in contact with the rim of the
fuel tank or container opening at all times, until
refuelling is complete. Do not use a nozzle lock-
open device.
g) Replace fuel cap securely and wipe up spilled
fuel.
h) If fuel is spilled on clothing, change clothing
immediately.
5. Adjust the height of the snowblower to clear gravel
or crushed rock surface. This is done by adjusting
the skid shoes.
6. Never attempt to make any adjustments while the
engine (motor) is running (except when specifically
recommended by manufacturer).
7. Let engine (motor), tractor and snowblower adjust
to outdoor temperatures before starting to clear
snow.
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 snowblower.
9. Never modify the snowblower or any part
without the written consent from the
manufacturer.
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), disconnect the wire from the spark plug(s)
and keep wire away to prevent accidental starting.
Thoroughly inspect the snowblower for any damage
and repair damage before restarting and operating
the snowblower.
4
SAFETY PRECAUTIONS
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 impeller/
collector housing or discharge chute, and when
making repairs, adjustments or inspections.
6. Take all possible precautions when leaving the
machine unattended. Disengage the power take-off,
lower the attachment, set the parking brake, shut
the engine off and remove the key.
7. When cleaning, unclogging, repairing or inspecting
the snowblower & tractor, make certain the
collector/impeller and all moving parts have
stopped. Disconnect wire from the spark plug(s)
and keep wire away to prevent accidental starting.
8. Do not run the engine indoors, except when
starting the engine and for transporting the
snowblower in or out of the building. Do not
operate or let motor run in a storage area without
ventilation because gas contains carbon monoxide
which is odourless, colorless and can cause death.
9. Do not clear snow across the face of slopes; go up
and down. Exercise extreme caution when
operating on slopes. Do not attempt to clear steep
slopes.
10. Never operate the snowblower without proper
guards, plates, or other safety protective devices in
place.
11. Never direct discharge at bystanders or operate
the snowblower near glass enclosures,
automobiles, window wells, drop-offs, and the like
without proper adjustment of the snow discharge
angle. Never allow anyone including children and
pets in the clearance area.
12. Do not overload the machine capacity by
attempting to clear snow at too fast a rate. Let the
snowblower ingest snow at its own rate.
13. Never operate the snowblower at high transport
speeds on slippery surfaces. Look behind and use
care when backing.
14. Do not carry passengers.
15. Disengage power to the collector /impeller to stop
all rotating parts when the snowblower is
transported or not in use.
MAINTENANCE AND STORAGE
1. Check shear bolts, engine mounting bolts, and
other bolts at frequent intervals for proper tightness
to be sure the snowblower 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 and space heaters,
clothes dryers, and the like. Allow the engine to
cool before storing in any enclosure.
3. Always refer to the owner’s manual when you store
the snowblower for an extended period.
4. Maintain or replace safety and instruction labels,
as necessary.
5. Run the snowblower a few minutes after throwing
snow to prevent freeze-up of the rotating parts
such as collector/impeller.
WHENEVER YOU SEE THIS SYMBOL
IT MEANS:
WARNING!
BECOME ALERT !
YOUR SAFETY IS INVOLVED!
16. Use only accessories approved by the
manufacturer of the snowblower (such as wheel
chains, counterweights, cabs). You must use 100
lbs. of rear counterweight for better traction and a
greater stability at all times when using a
snowblower that is installed on the front of a
tractor.
17. Never operate the snowblower without good
visibility or light.
CLEARING A CLOGGED DISCHARGE CHUTE:
Hand contact with the rotating impeller inside the
discharge chute is the most common cause of injury
associated with snowblowers. Never use your hand to
clean out the discharge chute.
To clear the chute:
1. Lower snowblower to the ground and set parking
brake.
2. SHUT THE ENGINE OFF & REMOVE KEY!
3. Wait 10 seconds to be sure the all moving parts
such as the impeller blades have stopped moving.
4. Disconnect wire from the spark plug(s) and keep
wire away to prevent accidental starting.
