3.052 REQUIRED BLEEDING OF THE FULL LOAD BRAKE SYSTEM
Bleeding the full load brake is required anytime air has been introduced into the system, and must al-
ways be performed by the dealer during the winch installation, in order to assure proper release of the
brake for winch drum rotation. Bleeding is accomplished by pressurizing the system and loosening the
bleeder screw on the top of the brake (shown on drawing 30578). To avoid fluid loss or spillage, a hose
should be connected to the top of the bleeder screw and the outlet of the hose directed to a can or similar
container. The brake should be bled until all the air is removed from the brake. Several cycles of pres-
sure bleeding may be required to remove all of the air from the brake.
The pressure from either side of the motor can release the brake. This feature enables the winch to pull
in as well as power out. The brake is not direction sensitive.
The maximum pressure rating is 3000 PSI (20684 kPa), including spikes or surges.
WARNING! SURGE PRESSURE IN EXCESS OF 3000 PSI (20684 kPa) GENERATED BY PUMP
SURGE OR RAPID OPENING OR CLOSING OF THE CONTROL VALVE WILL
CAUSE THE PISTON TO FRACTURE.
The O-rings (Buna ʺNʺ material) in the piston are only compatible with petroleum based fluid. DO NOT
USE NON - PETROLEUM BASED FLUID.
