FinalAdjustments
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.
WheelDriveControl& 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
_ ARNING: 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: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.
• 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.
• Repeat auger control test to verify for proper adjustment. Repeat previous steps to adjust more,
if necessary.
AugerControl
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
