Chute Clean-Out Tool
Figure 7
The chute clean-out tool is conveniently fastened to the
rear of the auger housing with a mounting clip. Should
snow and ice lodge itself in the discharge chute during
operation, proceed as follows to safely clean the chute
and chute opening:
Tire Chains
(If Equipped)
Tire chains should be used whenever extra traction is
needed. If your unit is not equipped with tire chains,
contact Customer Support as instructed on page 2 for
information regarding price and availability.
•
Release both the Auger Control Lever and the
Traction/Auger Control Lock Lever.
•
•
Stop the engine by removing the ignition key.
Remove the clean-out tool from the clip which
secures it to the rear of the auger housing.
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 discharge chute.
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.
•
WARNING: The temperature of the muffler
and the surrounding areas may exceed
150°F. Avoid these areas.
WARNING: Never use your hands to clean
snow and ice from the discharge chute 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 clutch lever
for a few seconds to clear any remaining snow and
ice from the discharge chute.
•
For the most efficient snow removal, remove snow
immediately after it falls.
Discharge the snow downwind whenever possible.
Slightly overlap each previous path.
Set the skid shoes 1/4" below the shave plate for
normal usage. The skid shoes may be adjusted
upward (to lower the shave plate) for hard-packed
snow. Adjust downward (to raise the shave plate)
when using on gravel or crushed rock.
Be certain to follow the precautions found in the To
Stop Engine section to prevent possible freeze-up.
Clean the snow thrower thoroughly after each use.

Drift Cutters
Drift cutters should be used when operating the snow
thrower in heavy drift conditions.
(If Equipped)
•
•
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 7.
If your unit is not equipped with drift cutters, contact
Customer Support as instructed on page 2 for
information regarding price and availability.
