AUGERS
The augers are secured to the spiral shaft with two
shear bolts and hex lock nuts. See Figure 21. If you
hit a foreign object or ice jam, the snow thrower is
designed so that the bolts will shear.
If the augers will not turn, check to see if the bolts
have sheared. A replacement shear bolt (P) and
hex lock nut (Q) have been provided with the snow
thrower. When replacing bolts, spray an oil lubricant
into shaft before inserting new bolts.
