4-5 ADJUSTING AXLE POSITION SWITCHES
The axle position switches are set up to detect when the boom lift load is transferred from
the trailer wheels to the outriggers. After the first 100 miles of road travel the axle torque
arms wear in. Torque arm wear-in causes the wheels to ride higher in relation to the trailer
frame. Following wear-in, the axle position switches need to be readjusted. Use the
following procedure to readjust the axle position switches:
1. Deploy the outriggers and raise the trailer wheels off the ground. The wheels
should spin freely.
2. Loosen the switch bracket, Figure 4-7.
3. Adjust the switch position to where the roller just touches the upper edge of the
torque arm. Tighten the switch bracket.
4. Repeat the adjustment procedure for the axle position switch at the opposite
wheel.
