Turn on the pump by pressing the MOTOR On/Off button once. The return relief valve pressure will be displayed on
the LCD screen. The pressure will be displayed for 5 to 20 seconds, depending on the Return Timer setting, after
this time the motor will switch off and the solenoid valve will switch to the idle position.
•
Remove the acorn nut and copper gasket and loosen the jam nut.
•
Start the pump as described above to build pressure in the return circuit. Then using an Allen key, turn the
adjustment set screw counter clockwise to decrease the pressure and clockwise to increase the pressure.
• Adjust the set screw until the pressure display reads 225 BAR.
•
Note: To get an accurate setting, decrease the pressure to a point below the final setting and then slowly increase
the pressure until it reaches the final setting.
•
Tighten the jam nut when the desire pressure is set and then replace the copper gasket and acorn nut. Then recheck
the final pressure setting by pressing the MOTOR On/Off button once and pressurising the system.

Priming the Hydraulic Hose Set

Before use, the Hydraulic Hose Set will need priming with oil to ensure all air is removed from each of the two hoses.
•
Take the first hose within the hose set and connect the male quick coupler on one end to the female quick coupler
on pump valve port A. Then take the female quick coupler on the other end of the hose and connect this to the male
quick coupler on pump valve port B.
•
Connect the pump unit to the power supply and switch on as described on pages 11 and 12.
•
Activate the LOCAL mode by displaying the 'LOCAL' menu and toggling the setting to 'ON' using the Arrow buttons.
Save the setting by pressing the MENU button and holding for 2 seconds.
•
Start the pump by pressing and holding the Up Arrow for approximately 20 seconds. Oil will be pumped from the
reservoir tank through port A and into the hose and then back into the reservoir via port B. Any air in the hose will
be expelled into the reservoir.
• Release the Up Arrow button and then press MOTOR On/Off button once to stop the motor. The solenoid valve will
then switch to the idle position.
•
De-activate the LOCAL mode by displaying the 'LOCAL' menu and toggling the setting to 'OFF'. Save the setting by
pressing the MENU button and holding for 2 seconds.
•
Disconnect the pump unit from the power supply and then disconnect the hydraulic hose from both valve ports.
• Repeat the above procedure to prime the second hydraulic hose.
