• 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.
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.

Engine Controls
STARTING CONTROLS
See Figures 1 and 2 for the following instructions.
Units with Optional Electric Start
A. Electric Start Button - The Electric Start Button
(A) activates an electric starter mounted to the
engine, eliminating the need to pull the starter handle. The Electric Start Button operates on 120 Volts
AC, which is provided by connection to the extension
cord provided with units equipped with this feature.
Connect this extension cord ONLY to a properly
grounded 3 prong electrical outlet.
Manual Start
B. Fuel Valve - The fuel valve (B) is located under the
fuel tank. It is used to turn the fuel supply off for outof-season storage.
C. Starter Handle - The starter handle (C) connects to a
starter cord to manually start the engine. Pulling
starter handle rapidly spins the engine crankshaft,
cycles the engine, and generates the spark necessary for starting the engine.
D. Primer Button - When pressed, the primer button
(D) provides initial fuel to help start a cold engine.
Normally, pressing the primer button twice will provide enough fuel to start a cold engine.
E. Throttle Lever - The throttle lever (E) controls the
engine speed. For best overall performance, the
throttle lever should be set to the FAST position. Use
the SLOW position only for warming the engine, or to
help prevent snow/ice freeze-up when shutting the
unit down for the day.
F. Engine Key - The Engine Key (F) prevents the
engine from being started by unauthorized individuals. The key must be fully inserted into the key slot
for the unit to start. The key is also used to stop the
engine by pulling the key out of the key slot.
G. Choke Knob - The Choke Knob (G) adjusts the
air/fuel mixture, and is used to help start a cold
engine by providing a richer mixture. Once the engine
is warm and running smoothly, the Choke Knob
should be set to the off position to provide a normal
air/fuel mix.

GROUND SPEED CONTROLS
A. Speed Selector - This lever (A, Figures 4 & 5) is
used to set the ground speed of the snowthrower.
The snowthrower has five forward speeds, 1–5, and
two reverse speeds, 1–2. No neutral position or gate
is required, since the traction drive design automatically provides "neutral" (no forward or reverse movement), whenever the Drive Control is released.
B. Traction & Free Hand™ Control - This control
engages the traction drive as the lever (B, Figures 4
& 5) is depressed, and disengages the traction drive
when the lever is released. When both levers are
depressed the Free Hand™ control is activated. This
allows the auger control to be released yet the auger
remains engaged until the traction Free Hand™ is
released. NOTE: Changing ground speeds must only
be done while the Drive Control is in the disengaged
(fully released) position.
AUGER CONTROL
C. Auger Control - The Auger Control clutch lever (C
Figures 4 & 5), engages the auger drive when the
lever is depressed and disengages the auger drive
when the lever is released (unless Traction Free
Hand™ control is also depressed-see above).
DEFLECTOR CONTROLS
D. Chute Direction Control - The Chute Direction
Control (D, Figures 4 & 5), allows the discharge chute
to be rotated to throw snow in the desired direction.
Snow may be thrown at any angle from straight left,
to straight forward, to straight right.
E. Chute Deflector - Controls the distance snow is
thrown. Tilting the Chute Deflector (E, Figure 5) UP
provides a higher stream and greater distance, while
tilting the deflector DOWN provides a lower stream
and less distance.
F. Chute Deflector Knob - This knob (F, Figures 4 & 5)
allows the discharge Chute Deflector (E) to be locked
in the desired tilt position.
SCRAPER HEIGHT
G. Scraper Bar Height Control - The Skid Shoes (G,
Figure 5) control the height the scraper bar (located
at the bottom of the auger housing). The scraper bar
allows smooth surfaces (such as concrete or asphalt
driveways) to be scraped clean of snow. On surfaces
such as gravel, the scraper bar should be adjusted
higher — so that it will not pick up gravel or debris.
TRACTION LOCK CONTROL
H. Traction Lock Pins - The traction drive to each
wheel can be locked and unlocked with the Traction
Lock Pins (H, Figure 5) to permit the unit to “freewheel,” allowing easier manual handling and transport
of the snowthrower.

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. Shut off the engine.
3. Remove the Engine Key.
4. Wait for moving parts to stop.
5. Disconnect spark plug wire.
6. Use a narrow board to remove foreign objects
and clear the chute or auger. Never put your
hands into the auger or discharge chute.

the snow contact side for the auger.
Figure 12. Traction Drive Lock - Engaged
AFTER EACH USE
Normal use of the snowthrower may result in a build-up
of packed snow in and around the starter cord housing
and around engine controls.
Heat from the engine will
usually prevent the snow from freezing solid while the
unit is running, but after the engine is shut down, some
snow may continue melting from engine heat, and later
freeze around some moving parts as the unit cools.
After each period of use, follow these steps
to prevent
freeze-up caused by ice formation
in and around the
engine controls and external parts.
1. Before shutting off the engine, pull the starter rope
out 2 - 3 times, and allow it to rewind slowly. This will
help clear packed snow from the starter cord area.
Allow the engine to run for several minutes.
2. Stop the engine by moving the Throttle Lever (See
Figure 8) down, or by pulling out the Engine Key.
3. Disconnect the spark plug wire, and position it away
from the spark plug.
4. Brush snow and ice from the snowthrower. Be sure to
clear engine and snowthrower controls, discharge
chute, worm and chute rod gears, clutch rod areas,
and anywhere else snow has accumulated.
5. Always remove the Engine Key and store in a safe
place to prevent unauthorized use.
6. If the snowthrower is kept in a cold shelter, fill the fuel
tank to prevent condensation. Do not store near
sparks or flame.
Note: The Engine Owner’s Manual contains further information on preventing ice formation and freeze-up.

Storage
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 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.

DRIVE BELT ADJUSTMENT (Continued)
Adjusting Auger Belt Guide
1. With the Auger Control still fully depressed, adjust
the Auger Belt Guide so that there is a 1/64” gap
(1/32” Maximum) between the end of the guide and
the belt (Figure 27), making certain the guide is NOT
putting pressure on the belt.
2. Making certain the Auger Belt Guide does NOT
move while doing so, tighten the Auger Belt Guide
Screw (Figure 27) to secure the guide.
3. Check the adjustment on the Auger Belt Guide
(Figure 27) to make certain that the gap between the
belt and the belt guide is correct.
4. Disengage the Auger Control by removing the cardboard tube (or other means used to temporarily
secure the control.)
5. Test the unit by following the steps under the
“Checking Auger Belt & Belt Guide Adjustments”
above.

DRIVE BELT REPLACEMENT
The snowthrower has two drive belts, one for the
Traction Drive—which transmits engine power to the
wheels, and a second for the Auger Drive—which trans-
mits engine power to the auger mechanism.
Each of these drive belts are of special construction and
should be replaced only with Genuine Replacement
Belts which match the original equipment belts. These
are available from your dealer. (See COMMON
REPLACEMENT PARTS at the back of this manual for
the correct part numbers for each of the belts.)
Traction Drive Belt Replacement
1. Disconnect spark plug wire and fasten it away from
the spark plug.
2. Remove belt cover.
3. Pull the traction drive belt idler pulley arm (See
Figure 23) away from the belt to relieve tension, and
slide the belt off the engine pulley.
4. Slip the belt off from around the traction pulley (See
Figure 28) and pull the belt out of the unit between
the auger pulley and the traction pulley (the lower
cover need not be removed for this step).
5. Reverse the procedure to install the new belt. Be
sure there are no twists in the belt, and that the belt is
properly seated in the pulley grooves.
6. Replace the belt cover.
7. Start the unit, and check the traction drive for proper
operation. See "Traction Clutch Rod Adjustment" for
adjustment procedures.
WARNING
Snowthrower must move only when the traction
Drive Control is depressed, and must stop when
the lever is released (disengaged).

Pins
SHEAR PIN REPLACEMENT
Under most circumstances, if the auger strikes an object
which could cause damage to the unit, the shear pin will
break. (This protects the gear box and other parts from
damage.)
The shear pins are located on the auger shaft as shown
in Figure 31. To replace the shear pins, tap out broken
pin with a pin punch, and install a new shear pin and cotter pin. Spread the legs of the new cotter pin fully. Do
NOT replace shear pins with anything other than the
correct grade replacement shear pin. See the
REPLACEMENT PARTS section at the back of this manual for the correct part numbers. (Use of bolts, screws or
a harder shear pin will lead to damaged equipment.)
