The outboard valve bank hydraulic system 13L circuit is supplied by hydraulic pump port 13L; pressure is
controlled by the relief valve at inlet port 13L.
WARNING
S
High oil pressure is present in the M9 hydraulic system. Do not disconnect any
hydraulic system pressure 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.
NOTE
Perform this procedure only when the winch and right--hand suspension controls are
inoperative.
