OPERATION
5. Re-fasten the clean-out tool to the mounting clip on the rear
of the auger housing, reinsert the safety key or connect the
spark plug wire and start the engine.
6. While standing in the operator’s position (behind the snow
blower), engage the auger control lever for a few seconds to
clear any remaining snow and ice from the chute assembly.

Replacing Shear Pins
CAUTION
NEVER replace the auger or central accelerator shear
pins with anything other than OEM Part No. 738-04124A
(round head replacement shear pins), 738-05273 (black
colored, round head replacement shear pins) or 738-
06654 (hex head replacement shear pins). Any damage
to the auger gearbox or other components as a result of
failing to do so will NOT be covered by your snow blower’s
warranty.
WARNING
Shut OFF engine, remove safety key or disconnect spark
plug wire prior to replacing shear pins.
The augers are secured to the spiral shaft with shear pins (a, b or
c) and cotter pins (d). If the auger should strike a foreign object or
ice jam, the snow blower is designed so that the pins may shear.
If the augers will not turn, check to see if the pins have sheared
(Figure 75).
IMPORTANT: ALWAYS use the correct OEM replacement shear
pin.
