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.
