ServicingAugers

The augers are secured to the spiral shaft with four

shear pins and cotter pins. If you hit a foreign object or

ice jam, the snow thrower is designed so that the pins

may shear. Refer to Figure 12.

If the augers do not turn, check if the pins have

sheared. Replace, if needed, with proper shear pins.

refer to item 22 on page 18 for part number.

IMPORTANT: NEVER replace the auger shear pins with

standard pins or fasteners. 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.
