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:
Place the shift lever in the
1.
fastest forward speed position (F6).
Loosen the hex nut on the shift cable index bracket. See Figure
2.
28.
Pivot the bracket downward to take up slack in the cable.
3.
Retighten the hex nut.
4.
If further adjustment is necessary move the shift cable to one of
5.
the alternate holes in the shift cable index bracket.
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:
With the drive control released, push the snow thrower gently
1.
forward. The unit should roll freely.
Engage the drive control and gently attempt to push the snow
2.
thrower forward. The wheels should not turn. The unit should not
roll freely.
With the drive control released, move the shift lever back and
3.
forth between the R2 position and the F6 position several times.
There should be no resistance in the shift lever.
If any of the above tests failed, the drive cable is in need of
4.
adjustment. Proceed as follows:
Shut off the engine as instructed in the Operation section.
5.
Loosen the lower hex bolt on the drive cable bracket. See Figure
6.
29.
Position the bracket upward to provide more slack (or downward
7.
to increase cable tension).
Retighten the lower hex bolt.
8.
Repeat Drive Control Test, steps 1-4 to verify proper adjustment
9.
has been achieved.
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 30.
To adjust this rod, proceed as follows:
Remove the cotter pin from the hole closest to the chute control
1.
head on the chute control input.
Pull out the chute control rod until the hole in it lines up with the
2.
other hole in the chute control input.
Reinsert the cotter pin through this hole and the chute control rod.
