Final Adjustments
Chute Directional Control Support Bracket
To adjust the chute directional control support bracket,
refer to Figure 8 and accompanying instructions.
Traction Control and Shift Lever
To check the adjustment of the traction control and shift
lever, proceed as follows:
Move the shift lever into sixth (6) position.
With traction control released, gently push the
snow thrower forward, then pull it back. The
machine should move freely.
Engage traction control, and try to move the
machine both forward and back. You should
experience resistance.
Move the shift lever into the fast reverse (R2)
position and repeat the previous two steps.
If you experienced resistance either when repositioning
the shift lever from 6 to R2 or when attempting to move
the machine with the traction control released, you
should NOT operate the snow thrower before adjusting
the traction control. To adjust, proceed as follows:
Loosen the jam nut on the traction control cable
and UNTHREAD the cable one full turn.
Recheck adjustment.
Retighten the jam nut to secure the cable when
correct adjustment is reached.
NOTE: For more details, refer to Traction Control
Adjustment on page 12.
Auger Control
Check the adjustment of the auger control as follows:
Push down on the auger control until the small
rubber bumper contacts the upper handle. There
