4. ADJUSTING REGULATOR CLEARANCE RECOVERY
TORQUES FOR SCREWS
ADJUSTING A CLEARANCE
The product is equipped with a regulator device to maintain the clearance of the
moving shank hinge in the main body. At the first assembly, the dealer makes the
correct adjustments of the device. Afterwards, it is the customer's responsibility to
periodically check the device and adjust the clearance as needed.
The first adjustment must be performed after 50 operating hours. Afterwards, adjust
whenever there is play in the shank.
Warning! Prior to maintenance or inspection, operate all the control levers to
their fully extended stroke. This will release pressure within the hydraulic
piping and prevent unexpected movement of the jaw and loss of oil through the
hydraulic lines.
Warning! Support the jaw to prevent it from closing unexpectedly during
maintenance.
1. Position the product on level ground.
2. Support the jaw.
3. Make sure the carrier's transmission is in neutral and the parking brake is
engaged.
