REMOVAL
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.
Do not work under vehicle unless hull is on jack stands and apron lockpins are installed.
Failure to comply may result in severe injury or death to personnel.
