Maintenance
Note: The motion control lever needs to be in
neutral while making any necessary adjustments.
7. Bring the motion control levers into the neutral
position. Adjust pump control rod lengths
by rotating the double nuts on the rod in the
appropriate direction until the wheels slightly
creep in reverse (Figure 33). Move the motion
control levers to the reverse position and while
applying slight pressure to the lever allow the
reverse indicator springs to bring the levers back
to neutral. The wheels must stop turning or
slightly creep in reverse.
