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.
