necessary). Retighten the wing nut to secure the
directional control in this position.

AUGER SHEAR BOLTS
The augers are secured to the auger 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. Two replacement shear
bolts and nuts are provided for your convenience. Store in a safe
place until needed.
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.
