Service And Repair
14. Screw the check valve into its port in the manifold. Torque the housing to 20 - 50 ft-lbs (27 - 67 N•m). Turn the
service screw all the way up (CCW). You will hear the check valve drop into place just before the screw is all
the way up. Replace the protective plug over the service screw, and fully thread into place to ensure a good
seal.
15. Screw the air purge screw all the way down (cw), then back it off 2 - 3 turns counterclockwise.
WARNING
The air purge screw is retained by the hitch pin to limit travel. Do not attempt to
rotate beyond 3 turns.
16. Turn the pump on and let it run for about 2 minutes to purge air from the manifold's hydraulic cavities. While
the pump is still running, turn the air purge screw clockwise until it is completely closed.
17. Open the ball valve down line from the pump.
