Setting Pilot Relief Valve 595G, 700G & 800G
The Pilot Relief Valve (RV1 on hydraulic schematic) must be set at 6000 psi (415 bar).
The Pilot Relief Valve is located on the hydraulic reservoir (see drawing above left).
To set pilot relief valve:
1. While holding the pilot relief valve adjusting screw with a hex key, loosen the adjusting screw jam nut
with an open-end wrench
2. Turn the adjusting screw clockwise as far as it will go.
3. Back off adjusting screw counter-clockwise 1/4 to 1/2 turn.
4. While holding adjusting screw, tighten the adjusting screw jam nut.
Setting Reservoir Pressure Regulator:
The Reservoir Pressure Regulator (RR on the hydraulic schematic) must be set at 1.5 psi (0.1 bar). Check the air
pressure on Gauge (GA4), which is installed on the front of Regulator (RR).
The Reservoir Pressure Regulator is located inside the power unit enclosure on the back of the control panel.
Mounted on the side of the Regulator (RR) is the Reservoir Pressure Solenoid Valve (V4 on the hydraulic
schematic).
To set the reservoir pressure regulator:
1. Loosen jam nut and turn adjusting knob fully clockwise. This sets the regulator to 2 psi (0.14 bar).
Tighten jam nut.
2. When hydraulic oil temperature is below 75
o
F (24
o
C) and with engine running under load (vibrator running
or using flow meter), loosen jam nut. Turn adjusting knob counterclockwise until pressure reads 1.5 psi
(0.1 bar). Tighten jam nut.
