IMPORTANT
To prevent damage to the traction neutral switch, make sure that
nothing contacts the switch face during operation or adjustment. Do
not scratch the face of the neutral switch.
2. When the traction lever is in the N
EUTRAL
position, the clearance between the
face of the neutral switch and the pump lever should be from 2.4 to 2.5 mm
(0.09 to 0.10 inch) .

3. If the clearance is incorrect, loosen the jam nuts that secure neutral switch
to the bracket. Use the jam nuts to move the switch to the correct position.
Tighten the jam nuts from
18.4 to 22.4 N·m (162 to 198 in- lb) . Re-check the
switch to lever clearance and adjust if necessary.
4. After adjusting the neutral switch, use the TDM display/controller screen to
verify that neutral switch and circuit wiring are functioning correctly.
Testing the Traction Neutral Switch
The traction neutral switch and its circuit wiring can be tested using the TDM
display/controller main information screens (neutral icon); refer to
Using the
TDM Display/Controller Screens for Troubleshooting (page 3–12) . If testing

proceed with the following test procedure:
1. Park the machine on a level surface, lower the cutting unit (or attachment),
engage the parking brake, set the key switch to the O
FF
position and remove
the key from the key switch.
2. Ensure that the traction neutral switch is correctly adjusted; refer to Adjusting
