into a trailer or truck.
• Keep in mind the operator is responsible for accidents occurring to other people or property.
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 tipover 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.
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.
• 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 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.

GENERAL OPERATION
CHECKS BEFORE EACH START-UP
1. Make sure all safety guards are in place and all nuts,
bolts and clips are secure.
2. Check the engine oil level. See your engine Owner’s
Manual for procedure and specifications.
3. Check to make sure spark plug wire is attached and
spark plug is tightened securely. If necessary, torque
spark plug to 15 ft. lbs.
4. Check the fuel supply. Fill the tank no closer than 1/4
to 1/2 inch of top of tank to provide space for expansion. See your engine Owner’s Manual for fuel recommendations.
5. Check the Scraper Bar to make sure it is set at the
desired height. Adjust the Skid Shoes if necessary.
6. Check the Drive Control (B, Figure 2), and Auger
Control (C) for proper operation. If adjustment is
required, see the Service section for procedures.
7. Check the Chute Direction Control (D, Figure 2) for
proper operation. The discharge chute should rotate
freely in both directions. See the Service section for
adjustment procedures and troubleshooting.
8. Check the Chute Deflector (E, Figure 2) for proper
operation. The deflector should pivot freely up and
down when the Chute Deflector Knob is loosened.
9. Position the chute at the desired starting direction
and set the deflector at the desired angle.
10. Check the Speed Selector (A, Figure 2) for smooth
operation. The control must move freely into each
speed position gate and remain in position when

into all forward and reverse speed positions, contact
your local authorized dealer for assistance.
WARNING
For your safety, operation on slopes should be in
an up and down direction only. If it becomes
necessary to move across the face of a slope, use
caution and do not blow snow. Be very careful
when changing direction on a slope.
Proper winter footwear is recommended for the
operator to help prevent slipping. Never attempt
to clean snow from excessively steep slopes. The
maximum slope for any operation is 17.7% (10º).
WARNING
Gasoline is highly flammable and must be
handled with care. Never fill the tank when the
engine is hot or running. Always move outdoors
to fill the tank. Keep snowthrower and gasoline
away from open flame or spark.
WARNING
This unit is a “two-stage” snowthrower.
The first stage is the auger, which feeds the snow
back into the impeller housing. The second stage
is the impeller, which throws the snow out the
discharge chute. If bodily contact is made with
the auger or impeller when they are rotating,
severe personal injury will occur.
To avoid injury, keep others and yourself away
from the auger and the discharge chute whenever
the engine is running. Read and follow all of the
safety rules and warnings in this manual.
WARNING
To avoid serious injury, do not put your hands
into the auger housing or discharge chute. If
auger stalls or chute becomes plugged, use the
following procedure to remove objects or clear
the chute:
1. Release both the Drive and Auger Control
levers.
2. hut off the engine.
3. Remove the Engine Key.
4. Wait for moving parts to stop.
5. Disconnect spark plug wire.

TEMPORARY STORAGE
(30 DAYS OR LESS)
Remember, the fuel tank will still contain some gasoline, so
never store the unit indoors or in any other area where fuel
vapor could travel to any ignition source. Fuel vapor is also
toxic if inhaled, so never store the unit in any structure used
for human or animal habitation.
Here is a checklist of things to do when storing your unit
temporarily or in between uses:
• Keep in an area away from where children may come
into contact with it. If there’s any chance of unauthorized
use, remove the spark plug (s) and put in a safe place.
Be sure the spark plug opening is protected from foreign
objects with a suitable cover.
• If the unit can’t be stored on a reasonable level surface,
chock the wheels.
• Clean all debris and snow from the unit.
NOTE: If storing your unit between winter snow removal
jobs in a cold area, we suggest that you fill the fuel tank at
the completion of each job to prevent water condensation in
the fuel tank. Wait for engine to cool before filling tank.
LONG TERM STORAGE
(LONGER THAN 30 DAYS)
Before you store your unit for the off-season, read the
Maintenance and Storage instructions in the Safety Rules
section, then perform the following steps:
1. Drain crankcase oil and refill with a grade of oil that will
be required when unit is used again.
2. Coat all bare metal surfaces with paint or light coat of oil
to prevent rusting.
3. Clean external surfaces and engine.
4. Prepare engine for storage. See engine owner’s
manual.
5. Clean any dirt from the engine housing.
6. Cover air intake and exhaust outlet tightly with plastic or
other waterproof material to keep out moisture, dirt and
insects.
7. Completely grease and oil as outlined in the Normal
Care section.
8. If equipped, be sure the battery is filled to the proper
level with water and is fully charged. Battery life will be
increased if it is removed, put in a cool, dry place and
fully charged about once a month. If battery is left in,
disconnect the negative cable.
10. Drain fuel system completely or add a gasoline stabilizer
to the fuel system. If you have chosen to use a fuel stabilizer and have not drained the fuel system, follow all
safety instructions and storage precautions in this manual to prevent the possibility of fire from the ignition of
gasoline fumes. Remember, gasoline fumes can travel
to distant sources of ignition and ignite, causing risk of
explosion and fire.
NOTE: Gasoline, if permitted to stand unused for extended
periods (30 days or more), may develop gummy deposits
which can adversely affect the engine carburetor and cause
engine malfunction. To avoid this condition, add a gasoline
stabilizer to the fuel tank or drain all fuel from the system
before placing unit in storage.
STARTING AFTER
LONG TERM STORAGE
Before starting the unit after it has been stored for a long
period of time, perform the following steps.
1. Remove any blocks from under the unit.
2. Install the battery if it was removed.
3. Unplug the exhaust outlet and air cleaner.
4. Fill the fuel tank with fresh gasoline. See engine
manual for recommendations.
5. See engine owner’s manual and follow all instructions
for preparing engine after storage.
6. Check crankcase oil level and add proper oil if
necessary.
7. Inflate tires to proper pressure.
8. Start the engine and let it run slowly. DO NOT run at
high speed immediately after starting. Be sure to run
engine only outdoors or in well ventilated area.
WARNING
Never store the unit, with gasoline in engine or
fuel tank, in a heated shelter or in enclosed,
poorly ventilated enclosures. Gasoline fumes may
reach an open flame, spark or pilot light (such as
a furnace, water heater, clothes dryer, etc.) and
cause an explosion.
Handle gasoline carefully. It is highly flammable
and careless use could result in serious fire
damage to your person or property.
Drain fuel into an approved container outdoors
away from open flame or sparks.
