Instruction Manual
Column Press with Electric Pump “EE03116-CE”
4. TRANSPORT AND INSTALLATION.
The machine is delivered properly packed in a wooden pallet. For its handling, it is recommended to use a forklift truck or a crane. In the last case, it is necessary to
make the slings trespass the arc of the frame. When doing this operation, you should be cautious and prevent the flexible hoses and coupling from any damage.
The machine is stable enough to operate without fixing, but if it is placed in an area commonly operated by mobile machinery (cranes, lifting
equipment...) it is strongly recommended to fix it to the desired place by drilling the supporting plates.
ELECTRIC CONNECTIONS
Bear in mind the voltage indicated in the motor.
Make sure that the directional valve is in "C" position (neutral). Make sure that the motor is rotating in the direction indicated by the arrow. In the
opposite case, change the position of the cables and terminals of the motor. The last operation must be performed with the machine disconnected.
REPLACEMENT OF THE TRANSPORT PLUG
You should replace the transport plug on the tank cover by the pressurized plug supplied with the press (in the small plastic bag next to the lever of the distributor).
INSTALLING THE GAUGE
Replace the threaded plug in the top of the cylinder by the gauge which is supplied separately. Tighten the gauge cone to the gauge adaptor seat by
using a flat wrench size 22. Hold the gauge screen by hand during threading process and after reaching a comfortable reading position set the gauge
screen free so that it turns the last quarter solidarily with the thread.
There is an alternative gauge port in the electric pump with a 3/8" BSP thread.
CHECKING THE RIGHT OPERATION OF ALL DEVICES AND MECHANISM
1.
Turn the lever of the pump direction valve to "C" position and turn the main switch to 1.
2.
Press the start button (green) for an instantaneous current.
3.
Verify the rotation direction of the motor.
4.
If the direction is opposite to the narrow indicated in the motor, you should reverse the electric phases of the power supply. When doing this, machine
should be unplugged.
5.
Turn the pump direction valve lever to "A" position. Pushing de green button constantly, the piston should move forwards (extension). Check the
extension speed and maximum stroke.
6.
Once the piston is fully extended run the pump to increase the pressure. Check the working pressure in the gauge. Verify that there are no oil leaks in
the connections, gauge, etc.
7.
Turn the direction valve lever to "C" position to check that the pressure in the cylinder does not drop.
8.
Turn the direction valve lever to "B" and push the green button to retract the piston. Check the retraction speed.
9.
Test the emergency button. Unblock it and with de motor stopped, turn the directional valve lever "A" to "B" to depressurize the cylinder. Turn the lever
to "C" position and turn "0" the main switch.
Once all the steps have been completed, the machine is ready to be used. Repeat the sequence as many times as required to get the knowledge on how to work the
machine.
5. START-UP.
Operate the machine as per the preciously mentioned indications.
Repositioning the table height
Model EE03116.
Choose the right height and lift or descend the bed manually alternatively (from one column to the other one) and from hole to hole. Do it slowly to avoid the fall
of the bed.
VERY IMPORTANT
WARNING
: THE TABLE POSITIONING SYSTEM IS NOT CONCEIVED TO BEAR THE FORCE THE CYLINDER CAN
DEVELOP. IT MUST BE USED JUST TO POSITION THE TABLE.
Regulation of the maximum working pressure
The maximum pressure developed by the hydraulic system is 700 Kgr/cm². An internal security valve discharges when the system reaches that pressure.
In order to operate at a lower working pressure, you should proceed like follows:
You can find the pressure regulation screw on the tank cover. Loosen the nut lock and unscrew the regulation screw. Check gradually the pressure with
the gauge and after reaching the required pressure tight again the nut lock to prevent the system from undesired vibrations.
