AUGER SHEAR BOLTS
5.1.
The augers are secured to the spiral shaft with
two shear bolts and hex lock nuts. If you hit a for-
eign object or ice jam, the snow thrower is
designed so that the bolts may shear. 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.
NOTE:
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 warranty.
6. AUGER CABLE ADJUSTMENT
Periodic adjustment to the auger control cable may be
required due to normal stretch and wear on the auger
belt. Adjustment is needed if the augers seem to
hesitate while turning, but the engine maintains speed.

right side of the housing. See Figure 6.1.
