One of the safety devices the MX340G's got is the extractor piece located in the front part of the machine to
hold up the material and prevent from placing hands between the punch and the piece.
It has also got a screen to protect the user from any projections coming from the working piece. This
screen has a safety system to avoid the punch from descending if the screen is up. It would only work if the
user turns the key C to cancel this safety command, then it would be possible to work along with the hazard
light D.

5.1. Introduction
This manual is designed to be an useful tooling for the MX340G user since it has important information
about the usage and specifications of the machine. Therefore it is important to follow step by step all the
points detailed in this manual so to get to achieve a better understanding of the performance of the
machine.
5.2. Power supply of the machine
In order to feed up the machine, just set the Start switch to the CONNECTED position. Then, a label as the
one below will show up on the screen.
Picture14. Message system reset
Machine pilots for voltage and reset the system will illuminate. We perform the Reset by pressing the but-
ton on the control panel. The alarm lamp will turn off, if not so, make sure that there is no abnormal situa-
tion.
The machine is at the moment in a StandBy mode, where the machine is activated but it is in rest position
awaiting any order.
5.3. Activation of the machine
Once the machine is initialized and in StanBy mode, you may activate it to work with it following the steps
we describe below:
In order to do it correctly , please, press the key ON. Then you’ll spot a label on the LCD screen reading
what is said below:
Picture 15.Label indicating the machine is activated
The information represented in the previous Picture shows the current operation mode, in the display
(Manual or Automatic).In the lower line there is the meter of the machine which is increased every time the
pedal is pressed.

CNT: 0

INSTRUCTIONS BOOK OF HYDRAULIC PRESS MX340G 13
5.4. Working at manual mode
In this mode,follow the steps described next: Press the pedal to make the punching operation.Then you will
see on the LCD screen that the meter of the machine has been increased in one unit.
Picture 16. Information of the Manual Punching operation
In picture 16, you can see how the meter marks 1 punching operation now. Once that punching operation
has been completed,you may get your foot off the pedal.
You must keep in mind that this mode of performance permits the piston rod descend bit by bit as you are
pressing the pedal longer or not. When the lower route end is reached or when you raise your foot off the
pedal, the rod movement stops.
According to this way of performance, you may adjust the Lower route end to graduate the the going down
of the rod while you press the pedal and so you will be able to see how the machine keeps on descending
until the afored mentioned route end is reached.
Finally, it is important to remind that in this mode of performance the rod of the machine never goes in as-
cending direction, so in case you need it to go up, you should proceed as detailed in the following section.
5.5. Working at automatic mode
In order to go from MANUAL working mode to AUTOMATIC working mode, just press the AUTOMATIC
key. In doing so, the machine will ask you a confirmation and we press the AUTO key again. Then
the rod will activate going up. Such movement won’t stop until the machine has reached the Upper End
route. Except for that the AUTOMATIC mode is quite similar to the one described in the section 5.4.
However, we will point out below some of the differences we find:
Press the pedal to make the punching operation. Then you will see the meter of the machine increased in
one unit.
Picture 17. Information of the Automatic punching operation
In picture 17, you can see how the meter has increased again when pressing the pedal and now it is indica-
ting a 2. Once this operation has been finished, you may leave your foot off the pedal. Nevertheless in this
working mode, unlike in the other one, the piston rod will come back again to the rest position when it will
start up the going up movement until the lower end route is activated.
MANUAL
CNT: 1
AUTOMATIC
CNT: 2

INSTRUCTIONS BOOK OF HYDRAULIC PRESS MX340G 14
You should keep in mind that this working mode will also allow the rod to descend bit by bit to adjust the
going down by the positioning of the lower end route. Whenever you keep the pedal pressed the rod will
make a descending movement that will be only interrupted when the route end is activated. When you raise
the foot off the pedal the rod will invert the movement and will start up ascending.
5.6. Meter deletion
As you have read in the previous sections, MX340G has got a punching meter that increases everytime
you press the pedal. This fact could be useful in case you need to count the punching operations required
for either a specific piece or the operations a third user has carried out with your machine.
Óbviously, this meter can be deleted. In order to do it right, and supposing there is a label like this one on
the LCD screen, for instance, You have carried out 150 punching operations, keep on the following indica-
tions.
Picture 18. Information about the number of operations made.
It is important that the meter could be erased always and just when you find the machine ready to start wor-
king but without doing any operation (in StandBy mode it is not possible), so it is possible in Automatic or
Manual mode.
Just press the COUNTER key. Then the message in the screen will change into this other one.
Picture 19. Message of information about the meter deletion.
It is obvious that if you press ESC key, the meter will not be affected and it will go back to the previous
screen. On the other hand, in case you wish to delete the meter when you see the question made by the
previous screen, just press COUNTER key again.the new message will show up as follows on the screen.

5.7. Desactivation of the machine
Any time that the activated machine is in rest position, you can deactivate it. If you wish so, please press
the key OFF and the machine will deactivate and will go to the StandBy mode (See section 5.2).
5.8. Unusual performance situations
An unusual performance situations may happen any time, it implicates to stop any operation that is being
carried out at the moment.
Unusual situations are divided into two big groups, Emergency situations and Error situations. Causes that
lead to both groups are specified below.
Situations of emergency:
Activation of the Emergency Stop.

INSTRUCTIONS BOOK OF HYDRAULIC PRESS MX340G 16
So, when we face one the aforementioned situations, the machine goes to such a estate that it aborts any
operation that is being performed at the moment, then a label will show up indicating the sort of unusual
situation sthat has occurred.
For safety reasons, it is not permitted a new activation of the MX340G until the unusual situation has been
solved ou. In case of Emeregency Situations, it can be solved out rearming the emergency Stop button.
Once it has been done the machine will restart and it will go into a StandBy mode (please see section 5.3
for a further activation of the MX340G).
In case an Error situation occurs, with the intention of preventing from bigger damages or hazardous situa-
tions for the users, the MX340G will remain blocked and the corresponding label will come out on the
screen. In this case the machine can be unblocked by unpluging it from the power supply and plugging it
again afterwards. Anyways in case any of these situations occurs, please contact our Technical Service so
the problem can be solved out as soon as possible.
