Auger Control

Periodic adjustment to the auger control cable may be required

due to normal stretch and wear on the belt. Adjustment is

needed immediately if the augers:

a. Continue to turn with the auger control disengaged, or

b. During operation, augers seem to hesitate turning

while the engine maintains speed.

NOTE: Perform the following test before operating the snow

thrower for the first time and at the start of each winter season.

Check the adjustment of the auger control as follows:

1. When the auger control is released and in the disengaged

“up” position, the cable should have very little slack, but

should NOT be tight.

2. In a well-ventilated area, start the snow thrower engine as

instructed in the engine manual. Make sure the throttle is set

in the FAST position.

3. While standing in the operator’s position (behind the snow

thrower) engage the auger.

4. Allow the auger to remain engaged for approximately 10

seconds before releasing the auger control. Repeat this

several times.

5. With the engine running in the FAST position and the

auger control in the disengaged “up” position, walk to the

front of the machine.

6. Confirm that the auger has completely stopped rotating

and shows NO signs of motion.

NOTE: 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 adjusting the auger control cable

as follows:

7. Loosen the rear hex screw on the cable adjustment bracket.

See Fig. 3-8.

8. Slide the cable adjustment bracket forward adding a slight

amount of slack in the auger cable.

9. Retighten the rear hex screw.

10. Start engine and verify auger control engages and

disengages properly.

NOTE: If auger continues to rotate with the control

disengaged, shut off engine and readjust.

11. If during operation, augers seem to hesitate turning while

the engine maintains speed, then the cable is too loose and

the bracket needs to be adjusted rearward, decreasing the

amount of slack to the auger cable. Follow the above steps

to adjust the cable adjustment bracket.

WARNING! Do not over-tighten the cable.

Overtightening may prevent the auger from

disengaging and compromise the safety of the snow

thrower.
