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.
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.

WARNING: NEVER attempt to make any
adjustments while the engine is running,

Drive Control and Shift Lever
To check the adjustment of the drive control and shift

To check the adjustment of the traction control
clutch 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
released, push the snow thrower forward. The unit
should roll forward. Then engage the drive control.
The wheels 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
wheels should keep turning.
If you have resistance when moving the shift lever
or the wheels stop when they should not, loosen
the jam nut on the drive control cable and unthread
the cable one turn.
If the wheels 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.
If you are uncertain that you have reached the correct
adjustment, proceed as follows:
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.
Tip the snow thrower forward, allowing it to rest on
the auger housing. See Figure 8.
