The hydraulic control valves on the directional control valve bank are activated by mechanical linkages from the
operator’s compartment which then activate hydraulic functions of the vehicle.
WARNING
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 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.
NOTE
Perform this procedure only when all hydraulic functions are inoperative. Refer to
HDC hydraulic system schematic (FP--1 through FP--6).
