SAFETY RULES
GENERAL OPERATION
• Read, understand, and follow all instructions in the
manual and on the unit before starting.
• Only allow responsible adults, who are familiar with the
instructions, to operate the unit (local regulations can
restrict operator age).
• Clear the area of objects such as rocks, toys, wire, etc.,
which could be picked up and thrown.
• Be sure the area is clear of other people. Stop unit if anyone enters the area.
• Always look down and behind before and while travelling in
reverse.
• Be aware of the discharge direction and do not point it at
anyone. Do not point the discharge at glass enclosures,
automobiles, or windows.
• Disengage all clutches (release drive and auger control
levers) before starting the engine.
• Never leave a running unit unattended. Always disengage
the auger and traction controls, stop engine, and remove
keys.
• Stop engine before unclogging chute.
• Operate only in daylight or good artificial light.
• Do not operate the unit while under the influence of alcohol
or drugs.
• Watch for traffic when operating near or crossing roadways.
• Use extra care when loading or unloading the unit into a
trailer or truck.
• Keep in mind the operator is responsible for accidents
occurring to other people or property.
• Data indicates that operators, age 60 years and above, are
involved in a large percentage of power equipment-related
injuries. These operators should evaluate their ability to
Read these safety rules and follow them closely. Failure to obey these rules could result in loss of control
of unit, severe personal injury or death to you, or bystanders, or damage to property or equipment.
The triangle in text signifies important cautions or warnings which must be followed.
SLOPE OPERATION
Slopes are a major factor related to loss-of-control and tip-over
accidents, which can result in severe injury or death. All slopes
require extra caution. If you cannot back up the slope or if you feel
uneasy on it, do not operate on it.
Do
• See your authorized dealer for recommendations counterweights to improve stability.
• Travel up and down slopes, not across.
• Remove obstacles such as rocks, tree limbs, etc.
• Watch for holes, ruts, or bumps. Uneven terrain could overturn the unit. Snow can hide obstacles.
• Use slow speed. Tires may lose traction on slopes. Choose
a low gear so that you will not have to stop or shift while on
the slope.
• Keep all movement on the slopes slow and gradual. Do not
make sudden changes in speed or direction.
• Always keep unit in gear especially when traveling downhill.
Do Not
• Do not start or stop on a slope. If tires lose traction, disengage the auger and proceed slowly straight down the
slope.
• Do not turn on slopes unless necessary, and then, turn
slowly and gradually downhill, if possible.
• Do not operate near drop-offs, ditches, or embankments.
The unit could suddenly turn over if a wheel is over the
edge of a cliff or ditch, or if an edge caves in.
• Do not operate on wet surfaces. Reduced traction could
cause sliding.
• Do not shift to neutral and coast down hills.
EMISSIONS
• Engine exhaust from this product contains chemicals
known, in certain quantities, to cause cancer, birth defects,
or other reproductive harm.
• Look for the relevant Emissions Durability Period and Air
Index information on the engine emissions label.
WARNING
Never operate on slopes greater than 17.6 percent (10°) which
is a rise of 3-1/2 feet (106 cm) vertically in 20 feet (607 cm)
horizontally.
When operating on slopes use additional wheel weights or
counterweights. See your dealer to determine which weights
are available and appropriate for your unit.
Select slow ground speed before driving onto slope. Travel UP
and DOWN the slope, never across the face, use caution when
changing directions and DO NOT START OR STOP ON
SLOPE.
operate the unit safely enough to protect themselves and
others from injury.
• All operators should seek and obtain professional and practical instruction.
• Always wear substantial footwear and appropriate winter
clothing. Wear foot-ware that improves traction on slippery
slopes. DO NOT wear long scarves or loose clothing that
could become entangled in moving parts.
• Before using, always visually check that all hardware is
present, in-tact, and secure. Replace worn or damaged
parts.
• Never operate the machine with defective guards, or without safety protective devises in place.
• Stop engine before: refuelling, removing an attachment,
making adjustments (unless the adjustment can be made
from the operator’s position).
• Follow the manufacturer’s recommendation for wheel
weights or counterweights.
• Adjust skid shoe height to clear gravel or crushed rock surfaces.
• Do not touch snowthrower parts which may be hot from
operation. Allow such parts to cool before attempting to
service the unit.
CLEARING A CLOGGED DISCHARGE CHUTE
Hand contact with the rotating impeller inside the discharge
chute is the most common cause of injury associated with
snowthrowers. Always use a clean out tool, not your hands. to
clean out the discharge chute.
To clear the chute:
1. SHUT OFF THE ENGINE.
2. Wait 10 seconds to be sure the impeller blades have
stopped rotating.
3. Always use a clean out tool, not your hands.
