Final Adjustments
Make these final adjustments before operating your
snow thrower for the first time. Failure to follow these
instructions may cause damage to the snow thrower.
Wheel Drive Control & Shift Lever
Perform the following test to determine need for
adjustment:
Move the shift lever into sixth (6) position. See
Figure 11.
With the drive control released, push the snow
thrower forward, then pull it back. The machine
should move freely.
Engage the drive control and attempt to move the
machine both forward and back, resistance should
be felt.
Move the shift lever into the fast reverse (R2)
position and repeat the previous two steps.
If you experienced resistance rolling the unit, either
when repositioning the shift lever from 6 to R2 or when
attempting to move the machine with the drive control
released, adjust the drive control immediately. 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 Wheel Drive Control
Adjustment in the Adjustment Section of this manual.
Auger Control
Check the adjustment of the auger control as follows:
When the auger control is released and in the
disengaged “up” position, the cable should have
very little slack, but should NOT be tight. See
Figure 8.
Figure 8
In a well-ventilated area, start the snow thrower
engine as instructed on page 10. Make sure the
throttle is set in the fast position.
While standing in the operator’s position (behind
the snow thrower) engage the auger.
Allow the auger to remain engaged for
approximately ten seconds before releasing the
auger control. Repeat this several times.
With the engine running in the fast position and the
auger control lever in the disengaged “up” position,
walk to the front of the machine.
Confirm that the auger has completely stopped
rotating and shows no signs of motion.
IMPORTANT:
If the auger shows any signs of rotating,
immediately return to the operator’s position and shut
off the engine. Wait for all moving parts to stop before
readjusting the auger control cable.
To readjust the control cable, unhook the spring
(found on the end of the auger cable) from the
auger actuator bracket. See Figure 9.
Push the cable coupler through the end of the
spring to expose the lock nut. See Figure 10.
