To Engage Augers
To engage the augers and start throwing snow,
squeeze the auger control lever against the left
handle. Release to stop the augers.
To Steer (If Equipped)
With the drive control lever engaged, squeeze the
right steering trigger control to turn right. Squeeze
the left steering trigger control to turn left.
CAUTION
Operate the snow blower in open areas and at slow
speeds until you are familiar with the drive control and
comfortable operating the steering controls.
Replacing Shear Pins
CAUTION
NEVER replace the auger shear pins with anything
other than OEM Part No. 738-04124A (gold colored
replacement shear pins) or 738-05273 (Black colored
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!
Always turn OFF the snow blower’s engine and remove
the key prior to replacing shear pins.
The augers are secured to the spiral shaft with
shear pins (a) and cotter pins (b). 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. See Figure 3-15.
IMPORTANT:
ALWAYS use the correct OEM
replacement shear pin.

Clearing a Clogged Chute
Assembly
WARNING!
Never use your hands to clear a clogged chute assembly.
Shut OFF engine and remain behind handles until all
moving parts have stopped before unclogging.
The chute clean-out tool is conveniently
fastened to the rear of the auger housing
with a mounting clip. Should snow and ice
become lodged in the chute assembly during
operation, proceed as follows to safely clear
the chute assembly and chute opening:
1.
Release both the auger control lever/bail
and the drive control lever/bail.
2.
SHUT THE ENGINE OFF! Refer to the
Engine Operator’s Manual. Remove the
safety key.
3.
Remove clean-out tool from the clip
which secures it to the rear of the auger
housing.
4.
Use the shovel-shaped end of the clean-
out tool to dislodge and scoop any snow
and ice which has formed in and near
the chute assembly. Always use the
clean-out tool (Part # 931-2643), not your
hands. Refer to the separate supplement
for clean-out tool ordering information.
See Figure 3-16.
5.
Re-fasten the clean-out tool to the
mounting clip on the rear of the auger
housing, reinsert the safety key and start
the snow blower’s engine.
6.
While standing in the operator’s
position (behind the snow blower),
engage the auger control lever/bail for
a few seconds to clear any remaining
snow and ice from the chute assembly.
