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.
WARNING: Do not over-tighten the cable.
Over-tightening may prevent the auger from
disengaging and compromise the safety of the
snow thrower.
• 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:
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.
• Thread the lock nut outward (down the coupler)
three full turns to provide more slack in the cable
and reattach the spring to the bracket.
