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 10.
If the augers do not turn, check if the bolts have
sheared. Replace, if needed, with proper shear bolts.
refer to item 52 on page 18 for part number.
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.
Figure 14
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 14.
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 15. 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.
