Augers
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 Fig. 5-1.
If the augers do not turn, check if the pins have sheared. Replace,
if needed, with proper shear pins. Refer to Parts List for correct
part number.
CAUTION:
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.
Replacing Belts
1. Allow the engine to run until it is out of fuel. Do not
attempt to pour fuel from the engine
2. Remove the key to prevent accidental starting.
3. Remove the self-tapping screw shown in Fig. 7-1, and press
the plastic tabs to release the belt cover. Pull the belt cover
up and out from around the engine and chute assembly.
Set it aside and save.
