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.
NOTE: If excessive slack is present in the drive cable or if the snow
thrower’s drive is disengaging intermittently during operation,
the cable may be in need of adjustment.
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.
If any of the above tests failed, the drive cable is in need of
adjustment. Proceed as follows:
1. Shut off the engine as instructed in the separate engine
manual.
2. Loosen the lower hex screw on the drive cable bracket. See
Figure 6-6.
Figure 6-6
3. Position the bracket upward to provide more slack (or
downward to increase cable tension).
4. Retighten the upper hex screw.
5. Check the adjustment of the drive control as described
above to verify proper adjustment has been achieved.
Auger Control
Refer to the Assembly and Set-up section for instructions on
adjusting the auger control cable.
Chute Assembly
Refer to the Assembly and Set-up section for instructions on
adjusting the chute assembly.
Chute Assembly (Overhead Chute Control) (Models 2890 and 3090)
If the chute fails to remain stationary during operation, the
pre-load of the chute can be adjusted by tightening the hex nut
found on the front of the chute control assembly.
To increase the preload, tighten the hex nut clockwise in ¼ turn
intervals. See Figure 6-7.
Figure 6-7
If the chute directional control is difficult to crank, decrease the
preload by loosening the hex nut counterclockwise in ¼ turn
intervals.
Skid Shoes
Refer to the Assembly and Set-up section for instructions on
adjusting the skid shoes.
