SECTION 3: KNOW YOUR SNOW THROWER
Figure 5
WARNING: Read, understand, and follow
all instructions and warnings on the
machine and in this manual before
operating.
Traction Control / Auger Control Lock
The traction control is located on the right handle.
Squeeze the traction control to engage the wheel drive.
Release to stop. See Figure 5.
This same lever also locks the auger control so you
can turn the chute directional control without
interrupting the snow throwing process. If the auger
control is engaged along with the traction control, the
operator can release the auger control (on the left
handle) and the augers will remain engaged. Release
the traction control to stop both the augers and track
drive (auger control must also be released).
IMPORTANT: Always release tractional control before
changing speeds.
Auger Drive Control
The auger drive control is located on the left handle.
Squeeze the control grip to engage the augers.
Release to stop the snow throwing action. (Traction
control must also be released.) See Figure 5.
Skid Shoe
The position of the skid shoe is determined by the
condition of the ground from where snow has to be
removed. See Figure 5.
Shift Lever
The shift lever is located in the center of the handle
panel and is used to determine both ground speed and
direction of travel. It can be moved into any of eight
positions. See Figure 5.
Forward
Your snow thrower has six forward (F) speeds. Position
number one (1) is the slowest. Position number six (6)
is the fastest.
Reverse
Your snow thrower has two reverse (R) speeds. R1 is
the slower, while R2 is the faster of the two.
IMPORTANT: Always release tractional control before
changing speeds.
Chute Directional Control
The chute directional control is located on left side of
the snow thrower. See Figure 5.
To change the direction in which snow is thrown, turn
chute directional control as follows:
• Crank clockwise to discharge to the left.
• Crank counterclockwise to discharge to the right.
Safety Ignition Key
The safety ignition key must be fully inserted in the
switch before the unit will start. Remove the ignition key
when the snow thrower is not in use. See Figure 5.
IMPORTANT: Do NOT attempt to turn the key.
