ALL HYDRAULIC FUNCTIONS INOPERATIVE
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 pressure is present in the M9 hydraulic system. Do not disconnect any hydraulic
system component unless hydraulic system pressure has been relieved. Ensure each
hydraulic control lever is moved several times through all positions and 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 hydraulic schematic in appendix E.
