Brake Adjustment Procedure Place machine on level surface and block wheels Reinstall clevis pin back into the clevis to prevent rolling in either direction. actuating lever. Unplug battery , disconnect plug. 10. Remove plastic plug located on the end of the Locate brake manifold in hydraulic/electric side caliper shaft.
Proximity Switch Replacement And Adjustment Procedure Figure 5-3. Traction Motor/Lift Pump Proximity Switch Location 1. To replace a proximity switch. First select either: lift mode to replace the PR2 proximity switch or traction mode to replace the PR1 proximity switch. 2.
A hand-held calibrator (Figure 5-5, Skyjack part #701051) can be plugged into the controller adjustment socket and used to digitally view or reset the parameters. The current value of these parameters will be shown on an LCD display. Additionally, the calibrator can perform certain measurements that can be useful for diagnostic purposes.
