3. MAINTENANCE AND CLEANING
There are two aspects to take in to account with respect to the maintenance and cleaning of the Horizontal
Press Brake NARGESA PP200, these are:
- Hydraulic Maintenance
- Cleaning maintenace
3.1. Hydraulic maintenance
As the Horizontal Press Brake NARGESA PP200 possesses a hydraulic mechanism, it is necessary to
periodically check the oil level tank. The machine is equipped with a low oil indicator (1) which permits us to
observe the level of oil. This should be carried out with the machine on the standby and off position.
Figure 7. Positions of the Hydraulic maintenance elements
If the level is low it should be filled with hydraulic oil HM68 through the tank cap (2) until it is visible in the
low oil indicator (1) (approximately half way up the indicator). This level should be checked once every
three months.
3.2. Cleaning
The daily usage of the Horizontal Press Brake NARGESA PP200 can generate metallic waste such as
(slag, shavings, etc.) which can damage the running of the machine. We recommend that the machine be
cleaned, especially the work area, at the end of each day.

INSTRUCTIONS BOOK HORIZONTAL PRESS BRAKE PP200 8
4. INSTALLATION AND START UP
4.1. Placement
The Horizontal Press Brake NARGESA PP200 should be placed on a flat, level surface. It is possible to
secure it to the floor using the pre-made holes on the base of the machine for this purpose.
Figure 8. Anchor points
4.2. Work Area
Given the versatility of the Horizontal Press Brake NARGESA PP200 it is important to have the necessary
working space, especially at the permiters of the machine, taking into account that the maximum or
minimum limitations will depend on the accessory used. The operator should stand behind the machine
together with the pedals.
Figure 9. Work area

INSTRUCTIONS BOOK HORIZONTAL PRESS BRAKE PP200 9
4.3. Acceptable external conditions
The working conditions of the machine can fluctuate between +5ºC and +50ºC being the maximum
temperature and not exceeding an average temperature of +45º in a 24 hour period.
The humidity can fluctuate between 30% and 90% without condensation.
4.4. Electrical connection
The Horizontal Press Brake NARGESA PP200 is designed to be connected to a
three-phase power supply of 230/400 volts at 50/60Hz.
Once connected ensure that the electric motor is turning in the correct direction
(the direction indicated on the sticker placed on the motor) if this is not so, one of the phases must be
relocated.
NOTE: If there is a change in voltage it will be necessary to modify the protectors of the electric
motor following the table below:

5. INSTRUCTIONS FOR USE
The Horizontal Press Brake NARGESA PP200 has two working modes:
• Step by step mode
• Normal or discontinued mode
Before explaining the working modes, we will describe the different components and characteristics of the
Horizontal Press Brake NARGESA PP200.
5.1. Description of the control panel
The Electrical control panel incorporating the different controls can be found on the side of the machine.
(see figure 10 below)
Figure 10. Control Panel
5.2. Start up
To start up the Horizontal Press Brake NARGESA PP200 first you must connect it to the mains electricity
supply inidicated in paragraph. 4.4. Once connected press the main switch and the voltage and alarm
indicators will appear. Unblock the emergency stop button, in case it is activicated, press the restart button.
The alarm indicator will now extinguish. Press the ON button.

Forward stop point knob (1) Backward stop point knob (2)
5.3. Displacement adjustments
As aforementioned the Horizontal Pree Brake NARGESA PP200 has a maximum displacement of 250mm,
this displacement may be excessive depending on the accessory used. To control the displacement, the
PP200 has a regulation panel on its side for the purpose of adjusting it.
Figure 11. Regulation panel
To regulate the position, the selected working mode must be taken into account: manual or automatic.
1. Manual mode:
Moving the limits of the displacement of the headstock forwards or backwards, the machine will move to
the position indicated by the stop knob.
2. Automatic mode:
Standby position: moving the backward stop point knob (2), the machine will move until it reaches the
indicated position automatically.
Setting the forward stop point has two options:
The first option is to move the forward stop point knob (1) to the required position and verify the position
using the pedals to advance until the machine reaches the indicated place.
The second option is, once the machine has reached the indicated position, keeping pressure on the pedal
move the forward stop point knob to the desired position, once set the machine will go forward until the
position indicated.
In this way we are able to carry out a more precise adjustment of the final position, releasing pedal will
regain the original position.
Once adjusted we advise you to run a trial cycle (without material) to verify the positions and if necessary to
repeat the operation.

INSTRUCTIONS BOOK HORIZONTAL PRESS BRAKE PP200 12
Pressure regulator Pressure gauge
5.4. Adjustment of the working strength
The Horizontal Press Brake NARGESA PP200 supplies 20,000Kg of strength.
This amount of power may be excessive depending on the type of work to be carried out. The PP200
incorporates a pressure regulatory system to allow us to decrease the strength of the machine.
Figure 12. Elements for the regulation of strength
To decrease the strength of the PP200 follow the procedure described below:
1. Place a resistant object over the headstock to act as a buffer.
2. Loosen the screw which blocks the pressure regulator.
3. Press the pedal so that the PP200 buffers the resistant object.
4. When buffered turn the pressure regulator towards the minus symbol. The pressure gauge,
situated to its right, will indicate a decrease in pressure value. When the ideal pressure is obtained release
the pedal.
5. Tighten the screw on the pressure regulator.
Now the PP200 is adjusted to use with less strength. Move the headstock back and remove the resistant
object.
To increase strength carry out the same procedure moving the pressure indicator to the plus symbol.
NOTE: Remember after decreasing the strength the PP200 will not be using its maximum power.

INSTRUCTIONS BOOK HORIZONTAL PRESS BRAKE PP200 13
5.5. Manual mode
The manual mode is the mode of work of the machine which is used to adjust and centre the different
accessories and shapes as it allows us total control over the movements of the machine.
The manual mode functions by pressing or releasing the pedals to move forwards or backwards. If the
pedal is releasesd the machine will stop in that position, the machine will also stop at the end of its
displacement.
5.6. Automatic mode
The automatic mode is the usual production mode.
In order to select the automatic performance mode, we press the “Automatic” key and the machine will ask
if we want to go into the “Automatic Mode”. We press the automatic key again in order to confirm.
The automatic mode functions by maintaining the pedal pressed until the machine reaches the point
indicated by the forward stop point knob, when the pedal is released the machine will reverse the
maneuvre until it reaches the standby position. If the pedal is released before end of trajectory the
machine will also reverse the maneuvre returning it to the standby position.
NOTE: The machine in use can be seen on our website: www.nargesa.com
