Auger Control Test
IMPORTANT: Perform the following test before
operating your snow thrower for the first time and at the
start of each winter season.
Check the adjustment of the
auger control as follows:
• When the auger control is
released and in the
disengaged “up” position,
the cable should have
very little slack. It should
NOT be tight.
WARNING: Do not over-tighten the cable.
Over-tightening may prevent the auger from
disengaging and compromise the safety of
the snow thrower.
• In a well-ventilated area, start the snow thrower
engine as instructed earlier in this section under the
heading “Starting Engine”. Make sure the throttle is
set in the FAST position.
• While standing in the operator’s position (behind
the snow thrower), engage the auger.
• Allow the auger to remain engaged for
approximately ten (10) seconds before releasing
the auger control. Repeat this several times.
• With the engine running in the FAST position and
the auger control in the disengaged “up” position,
walk to the front of the machine.
• Confirm that the auger has completely stopped
rotating and shows NO signs of motion.
IMPORTANT: If the auger shows ANY signs of rotating,
immediately return to the operator’s position and shut
off the engine. Wait for ALL moving parts to stop before
re-adjusting the auger control.
• To readjust the control cable,
loosen the hex jam nut on the
auger control cable “Z” fitting.
• Thread the ferrule without turning
the cable onto the “Z” fitting until
there is no slack in the cable. See
Figure 8. Do not overtighten the
cable. Hold the flats on the ferrule
with pliers and tighten the jam nut
against the ferrule.
• Rotate the coupling end of the cable
counterclockwise to provide more slack.
• Retighten the hex jam nut. See Figure 8.
• Repeat Auger Control Test to verify proper
adjustment has been achieved.

Clean-Out Tool
The chute clean-out tool is conveniently fastened to the
rear of the auger housing with a mounting clip. Never
use your hand to clean a clogged chute or chute
opening; use this clean-out tool instead.
• Release both the Auger Control and the Drive/
Auger Control Lock.
• Stop the engine by moving the throttle to the stop
position.
• Remove the clean-out tool from the mounting clip.
See Figure 6.
• 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.
WARNING: Never use your hands to clean
snow and ice from the chute assembly or
auger housing.
• Refasten the clean-out tool to the mounting clip on
the rear of the auger housing, reinsert the ignition
key and start the snow thrower’s engine.
• While standing in the operator’s position (behind
the snow thrower), engage the auger control for a
few seconds to clear any remaining snow and ice
from the chute before continuing to clear snow.
Drift Cutters
(If Equipped)
Drift cutters should be used when operating the snow
thrower in heavy drift conditions.
On models so equipped, drift cutters are assembled to
the auger housing inverted. Remove the carriage bolts
by unthreading the hex nuts which secure them, and
reinstall the drift cutters in their proper position before
operating the snow thrower. See Figure 9.
If your unit is not equipped with drift cutters, contact
Customer Support as instructed on page 2 for
information regarding price and availability.
