14. Set the high and low pressure control valves on the hydraulic manifold to the minimum
setting by turning them counter-clockwise.
If the machine is equipped with proportional pressure control, adjust the high pressure
setting from the controller.
15. Set the compensators to the minimum setting by turning the adjusting screws counter-
clockwise.
16. Select high pressure operating mode and set the high pressure control valve on the
hydraulic manifold to the maximum setting by turning the knob clockwise.
If the machine is equipped with proportional pressure control, adjust the high pressure
setting from the controller.
17. Turn the adjusting screw on the high limit compensator clockwise until the hydraulic
reference gauge reads 2,600 psi (179 bar).
18. Select low pressure operating mode and turn the adjusting screw on the low limit
compensator clockwise until the reference gauge reads 290 psi (20 bar). Lock the
adjustment screw in place.
19. Select high pressure operating mode and turn the knob on the high pressure control valve
counter-clockwise until the reference gauge reads 2,000 psi (138 bar).
If the machine is equipped with proportional pressure control, adjust the high pressure
setting from the controller.
20. Open the high pressure water control valve, allowing water to flow. Set the desired high
operating pressure by adjusting the high pressure control valve.
If the machine is equipped with proportional pressure control, adjust the high pressure
setting from the controller.
