Adjusting the Controls

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. Stop the engine and remove the key.
3. Pull straight back on the traction control so the front of
the control contacts the reference bar (Fig. 23).
