Adjustments
Shift Cable
If the full range of speeds (forward and reverse) cannot be achieved, refer to the
figure to the right and adjust the shift cable as follows:
1. Place the shift lever in the fastest forward speed position (F6).
2. Loosen the hex nut on the shift cable index bracket. See Figure 25.
3. Pivot the bracket downward to take up slack in the cable.
4. Retighten the hex nut.
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. Also, if there is excessive slack
in the drive cable or if the unit experiences intermittent drive while using, the cable
may need to be adjusted. 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 adjustment.
Proceed as follows:
a. Shut off the engine as instructed in the Operation section.
b. Loosen the lower hex bolt on the drive cable bracket. See Figure 26.
c. Position the bracket upward to provide more slack (or downward to
increase cable tension).
d. Retighten the lower hex bolt.
Chute Control Rod
To achieve more chute control rod engagement in the input shaft under the handle
panel, the chute control rod will have to be adjusted. Refer to Figure 27.
To adjust this rod, proceed as follows:
1. Remove the cotter pin from the hole closest to the chute control head on the
chute control input.
2. Pull out the chute control rod until the hole in it lines up with the other hole
in the chute control input.
3. Reinsert the cotter pin through this hole and the chute control rod.
