3. ESSENTIAL SAFETY REQUIREMENTS.
Due to the functional reasons, "dangerous area" is considered to be the space between the columns, the table and the hydraulic cylinder piston.
Due to the material pressed, "dangerous area" is supposed to be the surrounding area to the machine in case of metal parts being ejected during
pressing.
The speed of the hydraulic cylinder during its extension is less than 30 mm/second. Therefore the machine should be considered by the application of ANNEX V
of the Declaration of CE Conformity.
Operators standing in the dangerous area around the machine should protect their faces and feet form metal pieces being ejected during pressing.
Used materials and components are not for the health and safety of operators. The electric pump contains hydraulic oil type ISO: HV46
In any case, the hydraulic oil is toxic if it takes contact in the bloodstream, so that NEVER PLACE THE FINGERS OVER ANY HOLE THAT MAY
CAUSE A FILTRATION.
The start and stop operations of the motor are made with the commands of IP55 electric box. The commands are supplied with a 24 V. tension.
The advance and return movements of the cylinders are made by the hand lever located in the pump. This lever actuates over a directional valve.
The command have not maintaining action device due to the kind of operation that the equipment makes, the operator sometimes must place its hands over
the material to be treated. So that it forces to the operator to know the inherent risks and operating of the equipment.
The starting up of the motor is carried out by the green push button located on the electric box.
The rest of operating devices are activated manually from the directional valve on the cover of the pump.
To get cylinder movements, it is necessary to push the green button.
The red emergency push button stops the machine completely, in a safe way. To re-start it is necessary to unblock the emergency button.
It can be stopped too from the remote control
If you stop pressing the green push button, the motor stops and with it the cylinder movements.
The machine is equipped with the fuse and a thermo-magnetic switch for its protection.
The machine is equipped with supporting plates in the columns for a perfect stability. The machine gets operated without fixing onto the floor, but it is
strongly recommended to do it by drilling the plates in the place of your choice.
The construction of machine has been calculated to bear without any breaking under conditions of foreseen utilization and for the whole life of the
machine.
The hydraulic components have been designed and calculated in compliance with the ANSI B30.1
It is operator's responsibility to wear special protective clothes and attachments in both feet and face to prevent any damage as a result of accidental fallings
and breakings of metal pieces under operation or machine components in touch with.
Risks due to surfaces, bends and angles: The frame of the machine does not cause to be dangerous in that sense.
oRisk due to mobile components in setup stage: The table can be positioned in several fixing points.(weight of the table 21,5 Kg). The
EE012018 model is provided with a winch for the displacement of the table. It is operator's responsibility to wear safety shoes in any case.
There are 2 axle pins in equivalent holes of the lowest position to prevent operator's feet from being caught by the table.
oRisk due to mobile components during service: The operator must either move the directional valve lever to "C" position or press the red
button to fully stop the movement of the piston.
SAFETY PREVENTIVE ACTIONS AGAINST OTHER RISKS
Risk due to power supply: The machine is equipped with the fuse and a thermo-magnetic switch for its protection.
Risk due to hydraulic power: The hydraulic pump is equipped with an internal security valve in the tank, out of operator's control and rated at 700
Kgr/cm², as well as with a pressure relief valve on the tank cover adjustable by the operator from 0 to 700 Kgr/cm². The hydraulic cylinder is also
furnisher with a pressure relief valve, rated at 700 Kgr/cm², which prevents the retraction chamber of the cylinder from overpressures in case of
obstruction of the return way.
All the maintenance operations must be performed while the machine is stopped, thus avoiding this way any potentially dangerous situation.
A poor maintenance program of the press does not increase the risk, but obviously will revert in a lower performance.
The hydraulic pump is mounted in the frame and access is very easy. To disassemble the pump, unscrew the bolts in the tap cover. In order to
disassemble the cylinder it is required to first disassemble the piping.
Isolation of the power supply: Release the terminal wiring to disconnect the power supply. Previously you should unplug the pin.
Handling by the operator: The machine is designed to assure that all maintenance tasks are performed by the operator in an easy and safe way. All the
components that would require any maintenance operation are easy accessible.
In the valve, you can find several marks depending on the position of the lever:
•"A" for extension of the cylinder piston.
•"B" for holding the pressure without piston movement.
•"C" fir retraction of the cylinder piston.
The press, the cylinder and the electric pump have their corresponding serial numbers marked on them. In addition to it, you can find an sticker label showing the
commercial reference, capacity, working pressure, name and address of the manufacturer.

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 CAP
You should replace the a.m. cap on the tank cover by the pressurized cap supplied with the press (in the small plastic bag next to the lever of the distributor).
INSTALLING THE GAUGE
Replace the threaded tap 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.
2. Turn the main switch to 1.
3. Press the start button (green) for a instantaneous current.
4. Verify the rotation direction of the motor.
5. If the direction is opposite to the indicated in the motor, you should reverse the electric phases of the power supply. When doing this, machine should be
unplugged.
6. 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.
7. 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.
8. Turn the direction valve lever to "C" position to check that the pressure in the cylinder does not drop.
9. Turn the direction valve lever to "B" and push the green button to retract the piston. Check the retraction speed.
10. 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
Models EE012018
Choose the right height. Lift the table rotating the lever of the winch until you are able to extract the pin bearings. Place the table in an upper level than the desired
height. Place the pin bearings in the desired position. Descend the table by means of the winch until the table stands in the pins without any tension in the winch
cable.
VERY IMPORTANT WARNING: THE TABLE POSSITIONING SYSTEM IS NOT CONCEIVED TO BEAR THE FORCE THE CYLINDER
CAN DEVELOP. IT MUST BE USED JUST TO POSSITION 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.
