16 SECTION 3 — CONTROLS & OPERATION
Track Lock Lever
The track lock lever is located on the right
side of the snow thrower and is used to
select the position of the auger housing
and the method of track operation.
To move the track lock lever, shut off the
engine. Refer to the engine operators
manual. While standing on the right side
of the unit, place your left hand on the
right handle grip. Apply a light downward
force to the right handle and use your
right hand to adjust the track lock lever to
one of the four positions.
Transport
Raises the snow thrower auger housing
for easy transport.
Snow-covered Gravel
Raises the snow thrower auger housing
so that its shave plate leaves gravel
undisturbed while clearing snow.
Normal Snow
Adjusts the tracks to be level, for full auger
housing contact with the ground.
Packed Snow
Locks the auger housing down to the ground
for hard-packed or icy snow conditions.
Starting and Stopping the Engine
WARNING! Always keep hands
and feet clear of moving parts.
Do not use a pressurized starting
fluid. Vapors are flammable.
Refer to the Engine Operator’s Manual for
instructions on starting and stopping the
engine.
To Engage Drive
1. With the throttle control in the Fast
(rabbit) position, move the shift lever
into one of the six forward (F) positions
or two reverse (R) positions. Select
a speed appropriate for the snow
conditions and a comfortable pace.
2. Squeeze the drive control lever against
the handle and the snow thrower will
move. Release it and drive motion will
stop.
To Engage Augers
To engage the augers and start throwing snow,
squeeze the auger control lever against the left
handle. Release to stop the augers.
To Steer
With the drive control lever engaged, squeeze
the right steering trigger control to turn right.
Squeeze the left steering trigger control to
turn left.
CAUTION: Operate the snow
thrower in open areas and at
slow speeds until you are familiar
with the drive control and
comfortable operating the
steering controls.
Replacing Shear Pins
The augers are secured to the spiral shaft with
shear pins (a) and cotter pins (b). If the auger
should strike a foreign object or ice jam, the
snow thrower is designed so that the pins may
shear. If the augers will not turn, check to see if
the pins have sheared. See Figure 3-13.
NOTE: Three Stage shown.

Figure 3-13
IMPORTANT: On 3-stage units, there
is an additional shear pin in the rear
accelerator.
CAUTION: NEVER replace the
auger shear pins with anything
other than OEM Part No.
738-04124A replacement shear
pins. Any damage to the auger
gearbox or other components as
a result of failing to do so will
NOT be covered by your snow
thrower’s warranty.
WARNING! Always turn OFF
the snow thrower’s engine and
remove the key prior to replacing
shear pins.
Clearing a Clogged Chute Assembly
WARNING! Never use your
hands to clear a clogged chute
assembly. Shut OFF engine and
remain behind handles until all
moving parts have stopped
before unclogging.
The chute clean-out tool is conveniently
fastened to the rear of the auger housing
with a mounting clip. Should snow and ice
become lodged in the chute assembly during
operation, proceed as follows to safely clear
the chute assembly and chute opening:
1. Release both the Auger Control Lever
and the Drive Control Lever.
2. SHUT THE ENGINE OFF! Refer to the
Engine Operator’s Manual. Remove the
safety key.
3. Remove clean-out tool from the clip
which secures it to the rear of the auger
housing.
4. Use the shovel-shaped end of the
clean-out tool to dislodge and scoop any
snow and ice which has formed in and
near the chute assembly. Always use the
clean-out tool (Part # 931-2643), not your
hands. Refer to the separate supplement
for clean-out tool ordering information.
5. Refasten the clean-out tool to the
mounting clip on the rear of the auger
housing, reinsert the safety key and start
the snow thrower’s engine.
While standing in the operator’s position
(behind the snow thrower), engage the
auger control lever for a few seconds to clear
any remaining snow and ice from the chute
assembly.
