4 Functions of the press
The presses are equipped with a manually operated hydraulic unit.
This includes the direction control valve / joystick and hand pump.
4.1 Manual operated hydraulic unit
4.1.1 On / Off switch
The on / off switch is situated at the front of the hydraulic tank.
Pushing the red button will stop the motor on the hydraulic
unit immediately. All parts will stay in the position they are
at that moment
pressing force is being applied to the work
piece. Unexpected force expansion when
restarting, can damage the machine or injure
the operator.
Fig. 14 On / Off switch
4.1.2 Emergency stop button
To restart the hydraulic unit again:
Make sure that the dangerous situation has been resolved.
Reset the red emergency stop button by turning it counter
clockwise, the button will pop-up again.
Push the green button from the on / off switch again.
Fig. 15 Emergency stop button
WARNING: NEVER turn off the machine when
Pushing the green button will start the motor on the
hydraulic unit. There will be no movement of any part
after the motor starts running.
The emergency stop button is located on top of the on / off switch.
Pushing the red emergency stop button in case of emergency will
stop the electric motor on the hydraulic unit immediately. All other
parts will stay in the same position they are at that moment.

PAGE 13
4.1.3 Direction control valve
The direction control valve / joystick is located in the top cover of the hydraulic unit. The valve has 3
lever positions:
Middle position: if the lever has not been operated, the valve
will always return to this position. There is no movement of the
press ram.
Upper position: if the lever is positioned upwards, the press ram
of the cylinder will move upwards. As long as the valve is
operated, the press ram will move. When the lever is released,
the press ram will stop and stay in this position.
Fig. 16 Directional control valve
4.1.4 Pressure gauge
The pressure gauge is located in the head of the press. The gauge shows the pressure in psi & bars.
For the different types of presses the maximum pressure is as follows:
If this maximum pressure is reached, the maximum capacity of the press is reached as well.
4.1.5 Pressure control valve
Fig. 17 Pressure regulator
PressPro 66:
PressPro 110 & 110W:
PressPro 176:
3756psi (259 bar)
3742psi (258 bar)
3698psi (255 bar)
Lower position: if the lever is positioned downwards, the press
ram of the cylinder will move downwards. As long as the valve
is operated, the press ram will move. When the lever is
released, the press ram will stop and stay in this position. If
the press ram reaches its lowest position (end of the cylinder
stroke) the pressure of the cylinder will automatically drop to
almost zero, to prevent damages to the press ram head.
The pressure control valve is located in the top cover of
the hydraulic unit. The amount of force can be raised or
lowered with the pressure control valve. Turning the knob
clockwise will raise the pressure and turning the knob
counter clockwise will lower the pressure.

PAGE 14
4.1.6 Speed setting valve
Fig. 18 Speed setting valve
4.1.7 Hand pump
The press is equipped with a hand pump, located on the front panel
of the hydraulic unit. This pump can be used for manual pressing
functions or when accurate force setting is necessary.
To use the hand pump:
Turn off the hydraulic unit by pushing the red button of the
on / off switch.
Start pumping the hand pump with its lever.
Fig. 19 Hand pump
The speed setting valve is located in the top
cover of the hydraulic unit. Moving the lever
forward will slow the press ram and moving it
backward will speed up the press ram. When
the press ram contacts the work piece it senses
the pressure change and will automatically
switch to low speed. This has no impact on the
maximum capacity of the press.
Adjusting the pressure:
