Servicing Augers

The augers are secured to the spiral shaft with two shear bolts and hex lock nuts. If you hit a foreign object or ice jam, the snow thrower is designed so that the bolts may shear. Refer to Figure 9.

If the augers do not turn, check if the bolts have sheared. Two replacement shear bolts and hex lock nuts have been provided with the snow thrower. Refer to Loose Parts in the Assembly Section.

IMPORTANT: NEVER replace the auger shear bolts with standard hex bolts. Any damage to the auger gearbox or other components, as a result of doing so, will NOT be covered by your snow thrower’s warranty.

Making Adjustments

Auger Cable

Periodic adjustment to the auger control cable may be required due to normal stretch and wear on the belt. Adjustment is needed if the augers seem to hesitate while turning, but the engine maintains speed.

Auger Cable

Remove belt cover by pressing the tabs that secure it to the snow thrower housing. Pull the belt cover from around the engine and chute and keep it away. You can now access the auger cable.

Tighten two hex nuts on the auger cable towards the spring to increase the tension on the auger belt. See Figure 13.

Reassemble the belt cover.

Skid Shoe

The space between the shave plate and the ground can be adjusted. For close snow removal, place skid shoes in the low position. Use middle or high position when area to be cleared is uneven.

1.Adjust skid shoes by loosening the four hex nuts and carriage bolts and moving skid shoes to desired position. See Figure 14. Make certain the entire bottom surface of skid shoe is against the ground to avoid uneven wear on the skid shoes.

2.Retighten nuts and bolts securely.
