Adjusting the Tracking

Note: Determine the left and right sides of the machine
from the normal operating position.
1. Push both control levers forward the same distance.
2. Check if the machine pulls to one side. If it does,
stop the machine and set the parking brake.
3. Release the cushion from the rear of the machine.
4. Lift and remove the cable lock securing the cable
adjusting nuts (Figure 56).
5. Rotate the right cable adjustment to position the
right motion control in the center of the control
panel neutral lock slot (Figure 56).

6. Rotate the left cable adjustment to match the left
wheel speed to the previously set right wheel speed.
Adjust in quarter-turn increments until the machine
tracks straight.
Note: Only adjust the left cable to match the left
wheel speed to the right wheel speed. Do not adjust
the right wheel speed as this will position the right
motion control lever out of the center for the control
panel neutral lock slot.

7. Check for proper tracking.
Note: If the machine will not start after adjusting
the tracking, make sure proximity switch target aligns
with bolt attached to motion control lever. Refer to
Adjusting the Proximity Switch (page 40).
8. Repeat the cable adjustment until the tracking is
correct.
9. Check that the machine does not creep from neutral
with the park brakes disengaged.
Important: Do Not rotate the linkage too far, as
this may cause the machine to creep in neutral.
10. Install the cable lock onto the cable adjusting nuts to
secure the adjustment (Figure 56).
Adjusting the Proximity Switch
Use this procedure if the machine will not start after
adjusting the tracking.
1. Check and ensure the bolt attached to the motion
control lever aligns with the proximity switch target
(Figure 57).
2. If needed, loosen the bolts and adjust the proximity
switch until the target aligns with bolt attached to the
motion control lever (Figure 57).
3. Check the distance of the bolt to the proximity
switch. It needs to be between 0.050 and 0.090
inches (1.27 to 2.29 mm) (Figure 57).
