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.
NOTE: The temperature of the muffler and
the surrounding areas may exceed 150°F
(65°C).
• 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.
SECTION 5: MAKING ADJUSTMENTS
WARNING: NEVER attempt to make any
adjustments while the engine is running,
except where specified in the operator’s
manual.
Chute Assembly
The distance snow is thrown can be adjusted by
adjusting the angle of the chute assembly. Refer to
“Know Your Snowthrower” for instructions.
The remote chute control cables have been pre-
adjusted at the factory. Move the remote chute lever on
the control panel back and forward to adjust angle of
the chute assembly.
Auger Control
Refer to Auger Control Test in the Operating Section to
adjust the auger control.
Drive Control and Shift Lever
To check the adjustment of the drive control and shift
lever, proceed as follows:
• With the engine off, move the shift lever all the way
forward to the highest speed. With the drive control
lever released, push the snow thrower forward. The
unit should roll forward. Then engage the drive
control. The tracks should stop turning.
• Now release the drive control and push the unit
again.
• Move the shift lever back to the fast reverse
position then all the way forward again. There
should be no resistance in the shift lever, and the
tracks should keep turning.
• If you have resistance when moving the shift lever
or the tracks stop when they should not, loosen the
jam nut on the drive control cable and unthread the
cable one turn.
• If the tracks do not stop when you engage the drive
control, loosen the jam nut on the drive control
cable and thread the cable in one turn.
• Recheck the adjustment and repeat as necessary.
Tighten the jam nut to secure the cable when
correct adjustment is reached.
WARNING: Drain the gasoline out of the
snow thrower’s tank, or place a piece of
plastic film under the gas cap to avoid
spillage BEFORE making the adjustment.
To test further for correct adjustment, if necessary,
proceed as follows:
• Tip the snow thrower forward, allowing it to rest on
the auger housing. See Figure 10.
• Remove the frame cover underneath the snow
thrower by removing the six self-tapping screws.
• With the drive control released, there must be
clearance between the friction wheel and the drive
plate in all positions of the shift lever. See Figure
11.
