Traction Control and Shift Lever Adjustment
To check the adjustment of the traction control and shift
lever, proceed as follows:
• Move the shift lever into sixth (6) position.
a. With the traction control (refer to Figure 7 in
Section 4 of this manual) released, gently
push the snow thrower forward, then pull it
back. Disregarding the overall weight of the
snow thrower, the machine should otherwise
move freely.
b. Engage the traction control, and attempt to
move them machine both forward and
rearward. You should experience resistance
as the wheels should not be turning.
• Move the shift lever into the fast reverse (R2)
position and repeat the previous steps (a & b).
If you experienced resistance either when repositioning
the shift lever from 6 to R2 or when attempting to move
the machine forward or rearward with the traction
control released, your snow thrower’s traction control is
in need of adjustment and you should NOT operate the
machine before completing the adjustment as follows:
• Loosen the jam nut on the traction control cable
and UNTHREAD the cable one full turn.
• Recheck the adjustment.
• Retighten the jam nut to secure the cable when
correct adjustment is reached.
If the machine can be moved freely both forward and
rearward when the traction control fully depressed,
proceed as follows:
• Loosen the jam nut on the traction drive cable and
THREAD the cable in one full turn.
• Recheck the adjustment and repeat adjustment as
necessary.
• Retighten the jam nut to secure the cable when
correct adjustment is reached.
NOTE: If you are uncertain that you have reached the
correct adjustment, refer to Traction Control
Adjustment in Section 6 of this manual.

The traction control is located on the right handle.
Squeeze the traction control to engage the wheel drive.
Release to stop.
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 wheel
drive (auger control must also be released).
IMPORTANT: Always release tractional control before
changing speeds.
Headlight
The headlight is on whenever the engine is running.
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.
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.
