SERVICE & ADJUSTMENTS
Drive Control
When the drive control is released and in the disengaged “up” position,
the cable should have very little slack. It should NOT be tight.
Check the adjustment of the drive control as follows:
1. With the drive control released, push the snow thrower gently
forward. The unit should roll freely.
2. Engage the drive control and gently attempt to push the snow
thrower forward. The wheels should not turn. The unit should not
roll freely.
3. With the drive control released, move the shift lever back and forth
between the R2 position and the F6 position several times. There
should be no resistance in the shift lever.
4. If any of the above tests failed, the drive cable is in need of adjust-
ment. Proceed as follows:
5. Loosen the lower hex nut on the drive cable bracket. See Figure 22.
6. Position the bracket upward to provide more slack (or downward to
increase cable tension).
7. Retighten the lower hex nut.
Skid Shoes
The space between the skid shoes and the ground can be adjusted.
See Figure 23.
• For close snow removal on a smooth surface, raise skid shoes
higher on the auger housing.
• Use a middle or lower position when the area to be cleared is
uneven, such as a gravel driveway.
To adjust the skid shoes:
1. Loosen the four hex nuts (two on each side) and carriage bolts.
Move skid shoes to desired position.
2. Make certain the entire bottom surface of skid shoe is against the
ground to avoid uneven wear on the skid shoes.
3. Retighten nuts and bolts securely.
