User Adjustable Relief Valve:
Limits the pressure by opening the relief valve to redirect
the pump's oil flow to the reservoir at the desired
pressure value. Pressure will remain in the Advance
circuit (A port) while the Pendant "Up" button is pressed.
To adjust the pressure valve, Figure 5:
1. Verify "Auto Mode" is Off or "Set Pres" value is a
minimum 100 psi (7 bar) higher than the desired
relief valve setting.
2. Loosen the relief valve locking nut and turn the relief
valve control handle counter-clockwise until there
is a light drag when turning, this will decrease the
pressure value.
3. Start the pump to allow the oil to warm above 32°
F (0° C).
4. Press and hold the pendant Up button to build
pressure in the advance circuit. Turn relief valve
control handle clockwise to increase pressure to
desired value. 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.
5. Tighten the relief valve locking nut at the desired
pressure value.
6. Release the pendant Up button to allow the system
pressure to return to the B-port by-pass setting.
7. Recheck the final pressure setting by shifting the
valve and pressurizing the system.
Auto Cycle:
Limits the pressure by automatically changing the tube
pulling operation from Advance to Retract at the desired
pressure value. When the Retract pressure reaches a
factory-preset value of approximately 2,000 psi (138
bar), the pump automatically changes tube pulling
operation from Retract back to Advance. The pump
microprocessor does this by shifting the electric control
valve to redirect the pump's oil flow between ports. This
automatic cycling will continue while the pendant Up
button is pressed.
To activate Auto Cycle and adjust the pressure value:
1. Activate Auto Cycle by displaying the "Automode"
menu and toggling the setting to "On" using the
shroud arrow buttons. Save by pressing the Menu
button once.
2. Set the desired Advance pressure by displaying the
"Set Pres" menu and adjusting the value by using
the shroud arrow buttons. Save and return to the

"OK" display by pressing and holding the Menu
button for 2 seconds.
3. Turn on the pump by pressing the pendant On/Off
button.
4. Press and hold the pendant Up button to Auto Cycle
the tube puller.
5. If the tube puller does not Auto Cycle or does so
erratically, increase the User Adjustable Relief Valve
setting to a minimum value of 100 psi (7 bar) higher
than the desired Auto Cycle value.
NOTE:
also known as B port by-pass, is factory set at
approximately 2,500-2,800 psi (173-193 bar) and
cannot be adjusted.

Besides the Pendant, which is used to switch the motor
on/off and operate the valves, the Control Board with its
four-button switches is the main interface between the
operator and the pump. With the use of these four-button
switches all functions and settings that are described in
the following can be activated.

Make sure that all the plastic overlay, that
protects the LCD screen and the button
switches, is not broken or otherwise
damaged. Never punch the button switches
with a sharp or pointed instrument, user
fingertips only. Clean the overlay regularly
with a damp cloth; never use an aggressive
or abrasive detergent.
