EJECTOR DOES NOT EXTEND OR RETRACT
Ejector circuit oil is supplied by main pump outputs 13L and 13R. Oil enters main control valve through inlet ports
13L and 13R and combines at the ejector control valve section. When ejector control valve is shifted to the BACK
position, oil is supplied from port 22 and fed to rod end of ejector cylinder, which causes cylinder rod to retract,
pulling ejector back in bowl. When ejector control valve is shifted to FORWARD positing, oil is supplied from port
21 and fed to the ejector head end, causing cylinder rod to extend, pushing ejector forward in bowl. Pressure in
ejector circuit is limited by main relief valves 13L and 13R to 3,950-4,050 psi (27,235-27,925 kPa) and circuit
relieve valve 21, which limits pressure to extend the ejector cylinder.
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 to personnel.
