Valve bank hydraulic system is supplied by hydraulic ports 13L and 13R. Pressure is controlled by relief valves

13L and 13R.

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 or death to personnel.

NOTE

Perform this procedure when all driver controls are inoperative. Refer to vehicle

hydraulic system schematic diagram (FP--1 through FP--6).
