TROUBLESHOOTING PROCEDURE
WINCH AND RIGHT-HAND WHEEL CONTROL INOPERATIVE
WARNING
High oil pressure is present in the M9 ACE hydraulic system. Do not disconnect any
hydraulic system component unless hydraulic system pressure has been relieved. After
hydraulic system has been relieved, wait at least four 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.
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
The outboard valve bank hydraulic system 13L circuit is supplied by hydraulic pump port
13L; pressure is controlled by relief valve at inlet port 13L.
Perform this procedure only when the winch and right-hand suspension controls are
inoperative.
