Operating Instructions, Form No. 1000090, Back sheet 2 of 6
Adjusting The Hydraulic Gauge
Locate the adjustment screw on the gauge (see Figure 1) and make
adjustments as needed with a screwdriver. The adjustment screw is located on
the lower right back rim of the gauge. You must reach under the portion of the shroud
that the gauge is mounted in.
Priming The Pump
When operating the pump for the first time:
1. Valve and hose connections must be tight, and the reservoir must be filled to the proper oil level. Start the motor.
2. Jog the pump several times to build pressure. If the pump doesn't build pressure, it may not be primed.
Disconnect a hose from the system and route it back to the pump reservoir. Run the pump until a steady flow of
oil is observed free of suspended air bubbles. Reconnect the hose to the system.
3. Run wrench several times to eliminate air from the system. For more complete instructions, refer to the section
titled "Bleeding Air From The System."
4. The pump is ready to be put into regular operation.
IMPORTANT: After eliminating trapped air from a large work-holding system, retract the wrenchs and refill
the pump reservoir to 1/2" from the top of the filler hole.
Adjusting The Pressure Regulating Valve
NOTE: For easy adjustment of the pressure regulating valve, always adjust the pressure by increasing to the
desired pressure setting.
1. Loosen the locknut on the pressure regulating valve (C), and back the adjusting screw (B) out a few turns with a
screwdriver by turning in a counterclockwise direction. This will decrease the setting to a lower than desired
pressure.
2. The pump must be completely connected. Set the motor control toggle switch on "Run" and push the "Start"
button.
3. With the screwdriver, slowly turn the adjusting screw (B) in a clockwise direction. This gradually increases the
pressure setting. When the desired pressure is reached, lock the adjusting screw in position by tightening the
locknut.
IMPORTANT:
The pressure range is from 1,000 to 10,000 PSI depending on the pump model.
