Controls System
Maintenance
The factory adjusts the controls before shipping the traction
unit. However, after many hours of use, you may need to
adjust the traction control alignment, the neutral position of
the traction control, and the tracking of the traction control
in the full forward position.
Important:
To adjust the controls properly, complete
each procedure in the order listed.
Adjusting the Traction Control
Alignment
If the traction control bar does not rest flush and square
with the reference bar when in the full backward position,
immediately complete the following procedure:
1. Park the traction unit on a flat surface and lower the
loader arm.
2. Shut off the engine and remove the key.
3. Pull straight back on the traction control so the front
of the control contacts the reference bar (
Figure 54 ).

4. If the front of the traction control does not rest square
and flush with the reference bar, loosen the flange nut
and bolt in the stem of the traction control (
