SET-UP
Gasoline Engine
Refer to the instruction manual on the gasoline engine.
Hydraulic Connections
1.
Clean all the areas around the oil ports of the pump and cylinders.
2.
Inspect all threads and fittings for signs of wear or damage, and replace as needed.
3.
Clean all hose ends, couplers or unions.
4.
Remove the thread protectors from the hydraulic oil outlets. Connect the hose assembly to the hydraulic oil outlet,
and couple the hose to the cylinder. Although a high-grade, non-hardening thread sealant is preferred, teflon tape
can be used if only one layer of tape is used. Apply carefully to prevent the tape from being pinched by the
coupler and broken off inside the pipe end. Any loose pieces of tape could travel through the system and obstruct
the flow of oil.
Filling the Reservoir
NOTE: The pump has been shipped without oil in the reservoir. High-grade hydraulic oil has been shipped
with the pump in a separate container. If additional oil is required, use Power Team hydraulic fluids only.
1.
Clean the area around the filler cap to remove all dust and grit. Any dirt or dust in the oil can damage the polished
surfaces and precision-fit components of this pump.
2.
Retract all cylinders to the return position.
3.
Remove the filler cap, and insert a clean funnel and filter. Fill with hydraulic oil to 1/2" from the top of the filler
hole. Replace filler cap with the breather-hole in the filler cap open.
4.
Cycle the pump (with cylinders attached) several times. Retract the cylinders, and check the oil level in the pump
reservoir again.
OPERATION
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 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 cylinder out to its full travel 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 cylinders and refill
the pump reservoir to 1/2" from the top of the filler hole.
Adjusting the Pressure Regulating Valve
The pressure regulating valve can be adjusted to bypass oil at a given pressure setting while the pump continues to
run.
Figure 1
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 (B), and
back the adjusting screw (A) 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 to "Run" and push the "Start" button.
3.
With the screwdriver, slowly turn the adjusting screw (A) 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.
