The winch hydraulic motor receives oil flow from the control valve through circuit VA to PAY OUT cable and
through circuit VB to PAY IN cable. Hydraulic pressure is controlled by winch relief valve C2. The winch motor
case drain line is 7W.
WARNING
S
High oil pressure is present in the M9 hydraulic system. Do not disconnect any
hydraulic system component unless hydraulic system pressure has been relieved.
After hydraulic system pressure has been relieved, wait at least 4 minutes before
disconnecting any hose or fitting. Ensure each of the hydraulic control levers is
moved several times through all positions and the hydraulic tank dipstick is slowly
loosened to relieve pressure. Failure to comply may result in severe injury or
death to personnel.
S
Transmission shifting lines are pressurized. Do not disconnect lines, fittings, or
accumulator unless transmission shift control valve pressure has been relieved.
Discharge transmission shift accumulator by moving shift control lever through all
forward and reverse ranges several times, with engine off. Failure to comply may
result in severe injury to personnel.
CAUTION
Do not reuse drained captured hydraulic oil unless it has been filtered and is clean.
Failure to comply may result in damage to equipment.
