the parking brake pads. Be sure engine is shut off,
the ignition key is removed and chock blocks are in
place before climbing under the crane.
Inspect the thickness of the brake pads (Figure 6-22).
Replace the brake pads if they are 0.028 inches (0.71 mm)

instructed in the engine operator’s manual
furnished with the crane.
