Replacing Shear Pins
Each of the four auger spiral assemblies are secured to the spiral
shaft with a shear pin and cotter pin. If the auger should strike a
foreign object or ice jam, the snow thrower is designed so that
the pins may shear. If the augers will not turn, check to see if the
pins have sheared. See Fig. 5-3.
CAUTION: NEVER replace the auger shear pins with
anything other than OEM Part No. 738-04155
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 thrower’s
warranty.
WARNING! Always turn off the snow thrower’s
engine and remove the key prior to replacing shear
pins.
Operating Tips
NOTE: Allow the engine to warm up for a few minutes. The
engine will not develop full power until it reaches operating
temperature.

surrounding areas may exceed 150° F. Avoid these
areas.
If possible, remove snow immediately after it falls.1.
Discharge snow downwind whenever possible. 2.
Slightly overlap each previous path.3.
Set the skid shoes 1/4” below the shave plate for normal 4.
usage. Adjust them upward for hard-packed snow and
downward when using on gravel or crushed rock.
