The main winch combination control valve must be adjusted by the following ADJUSTMENT proce-
dures in this section and TESTING procedures in the next section so that the main winch will have a
capacity as specified in the DESCRIPTION above.
Test components (pressure gages, hoses, and fitting) must be capable of withstanding a working pressure
of 19502050 psi (13,44514,135 kPa).
VEHICLE PREPARATION--Perform steps 1 thru 4 for vehicle preparation.
Do not adjust brake if anchoring cable.
Place load on winch.
Use load cell if available and anchor.
If a load cell is unavailable, attach winch cable to an anchoring device or adjust winch brake full tight. Refer to
If using anchor or winch brake, use adjusting screw (111) on main winch combination control valve to reduce pressure as
far as possible. Turning in counterclockwise direction will decrease pressure.
