4.1.4 Pressure gauge
4.1.6 Speed setting valve
The speed setting valve is located in the top
cover of the hydraulic unit.
If the lever is in the lower position, the piston
will move with low speed when the directional
control valve is activated. If the lever is in the
upper position, the piston will move with high
speed when the direction control valve is
activated. When the piston is reaching the
work piece with high speed, it will
automatically switch to low speed as soon as
it feels counter pressure. This has no
influence on the maximum working pressure
or working force.
Fig. 12 Speed setting valve
The pressure gauge is located in the head (in front toward the top) of the press. The gauge shows
the pressure in psi & bars. For this press 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 regulation valve
Fig. 11 Pressure regulation
Adjusting the pressure:
Start the hydraulic unit.
Raise the press ram so no force is applied.
Turn the knob on the pressure control valve
counter clockwise to lower the pressure.
Do not remove the knob!!
Note that it can be turned far enough to unscrew from the pressure control valve.
Lower the press ram to the work piece and keep force applied with the joystick.
Slowly turn the knob on the pressure control valve clockwise & carefully raise the
pressure while watching the pressure gauge.
The pressure regulation valve is located in the top cover of the
hydraulic unit. With this valve the maximum pressure, referring
to the maximum press capacity, can be changed. Turning the
knob clockwise will increase the pressure, turning the knob
counter clockwise will reduce the pressure.
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:
Fig. 13 Hand pump
TURN OFF the hydraulic unit by pushing the red button of the
on/ off switch.
Set the directional control valve in the required position
(up- or downwards).
Start pumping the hand pump with its lever.
