5.3. Feeding of the guillotine
In order to power on the machine, it is enough jus by set the Go switch in the position o Connected. Then it
will show up al abel on screen as the one below:
Picture 8. Message of activation of the machine
The 7 fragments displays are checked automatically showing a sequence of numbers in regression. Once
this routine revision has been carried out all 7 fragment displays will turn off and will deactivate LCD display
light at the same time, however the same label of Picture 8 will seen .
Right now the machine is in a StandBy mode, it happens when it is activated but in rest position awaiting
any command the user orders.
5.4. Activation of the machine
With the machine already started and in StandBy, it could be activated to work with the steps detailed
below.
Press the key ON to proceed properly. Once you do it you will see a label like the one below and just in
case you finish giving power to the machine as it was described in the section below you will see in the
LCD display an initialization label as the one below
Picture 9. C2006 initialization label
At the same time it will be seen intermitently in the 7-fragments displays the total length of the top while this
is moved at a moderate speed, getting apart from the shears blade in order to be located in the highest
working figure.en la cota Once this top is located in the indicated positions, then the intermitence of the 7-
fragments displays will disappear and these ones will show the value of the top route length.
Likewise, there will be a label in the screen showing the following message which will show the in the
memory of the current top the cutting meter associated to this memory and the position of the top
corresponding to the visualized memory.

Picture 10. Information of the top memory 0
Apart from the information indicated in the previous picture in the upper picture of the LCD display it could
be seen the performance way of the shears, intermitently intercalated with the memory of the current top.
Such a mode allows to make cutting operations with the shears in both, the automatic mode and the
manual mode. So, depending on the performance mode currently selected, it will be seen on the screen a
label of Picture 11 or that of Picture 12, intercalated with the one on Picture 10
Picture 11. Information of the Shears in manual mode.
Picture 12. Information of the Shears in automatic mode.
In case the machine hasn’t been completely fed then it will show directly in the LCD display all information
shown in Picture 10, since in this case it is not necessary that the top goes back to the starting point again
on default. Likewise it will be possible to see the current top position of the machine on the 7-fragments
display.
5.5. Surfing throught the top memories
There are 10 preset memories of the top, all of them with the counter to 0 and the position of the top
gradually increased regularly in gaps of 10mm.
To go through the different memories, it is necessary to press the Navigation keys, silkscreen printed with:
To the pressure of each of these keys there will appear on screen the information according to the current
memory of the top.

C2006 HYDRAULIC SHEAR INSTRUCTIONS BOOK 15
To find the desired memory faster, keep the Navigations keys preddes for more than 1.5 sec. Keeping the
key pressed it will pass to the next memory every 0.25 sec.
An example of a top memory could be the one below:
Picture 13. Information of the memory of the top 6.
5.6. Positioning the top
Press the Return key at the sight of Picture 13 for the top to be located in the indicated figure every (70.0
mm)
Once this has been accried out the top will beging it positioning until it reaches the specified figure. We can
see the position of it in the 7-fragments display as it is moving. Like this we get to know in real time the
location of the top in our shears.
Therefore we can select the desired memory of the top amog the 16 possible ones and once it is displayed
on screen, press the return to confirm the top at which it must be set in the figure shown on the screen.
5.6.1. Introducing the desired figure
Despite the 10 preset memories of the top, it is quite probable to require intercalated which are not
reflected on these memories.
In order to enter the desired figure just insert the new value for the top positioning by using the number
keyboard. Once this value has been inserted, confirm it by pressing the return key, placing the top in the
new inserted position.
Let’s see an example of the steps to follow, with the new inserted figure of 443.2 mm:
Picture 14. Information of thetop of the memory 0
At pressing the first number ( 5 in our sample), the message on the screen changes into this other one:

C2006 HYDRAULIC SHEAR INSTRUCTIONS BOOK 16
Now we insert the second number followed by the third one, shown in this screen:
Picture 16. Inserting the new figure.
Picture 17. Inserting the new figure.
Next we press the key according to the Decimal Point, what enables us to see on the screen what follows:
Picture 18. Inserting a new figure
Finally, we insert the final number (2, in this example),getting a new figure as it can be seen in Picture 19:
Picture 19. Inserting a new figure
Once these simple steps are carried out, we press the Return Key to confirm the value that has been
inserted. Then unless the new inserted figures is not higher than the total length of the top, it could be seen
on the LCD displays the information reflected in the following picture:
Picture 20. Inserting a new figure

C2006 HYDRAULIC SHEAR INSTRUCTIONS BOOK 17
Right now the top will activate moving towards the specified position, what can be seen by taking a look at
the 7 fragments display. When the top reaches the desired figure it stops, and it is reflected in the seven
fragments displays.
Now that the top is in the new position, the information shown in the display is the one below:
Picture 21. Information of the memory of the top 0
Picture 22. Information of the guillotine in manual mode.
5.6.2. Cancelling the introduction of a figure
In case we have gone wrong while inserting thr new figure we can cancel the operation pressing the ESC
key

When we do that the memory of the current top shows up on screen again, with the value thet it had before
the modification we were going to make.

C2006 HYDRAULIC SHEAR INSTRUCTIONS BOOK 18
5.6.3. Considerations to bear in mind
It is impossible to insert a figure higher than the total effective length of the top. It is like that because it is
not possible to put the top beyond the physical limits that it has itself.
Therefore, if the total effective length of the top is 500.0 mm, we will see the memory of the current topwith
the value it had before, although we can insert on the screen a value higher to this one,such as 550.0 mm,
when we press the Return Key to confirm the new figure, we see the memory of the current top again with
the value that it had before its modification.
Picture 25. Information of the memory of the top 0
Picture 26. Modificating the memory of the top 0
When pressing the key return to confirm and due to the fact that the inserted figure is higher to the total
(500.0 mm), the top will not move and in the screen we will see the label on Picture 25 again:
Picture 27. Information of the top memory 0
5.7. Operation mode
As it has been pointed out before, the shears has two modes of performance, in order to make the cutting
operations. These are: Manual mode and Automatic mode.
In the memories of the top, the performance mode of the machine is Manual on default. This performance
mode is the same for each o f the 10 memories the top has and that could be changed if desired. Just
follow the steps detailed below if the performance mde of the shears wants to be changed:
If your intention is to work with the machine in the automatic mode, press the AUTO key. Once this has
been done you will see how the shears blade will go up til the upper rest position.
If on the other hand your intention is to operate in Manual mode, the only thing to do is to press the Manual
key. In this case, unlike the previous one, the blade will not move.
M00 CONT: 0000

M00 CONT: 0000
TOP = 550.0 mm
M00 CONT: 0000
TOP = 50.0 mm

C2006 HYDRAULIC SHEAR INSTRUCTIONS BOOK 19
5.7.1. Manual mode
If your choice is to make the cutting operations with the shears in Manual mode, then proceed by following
the information indicated in the following pictures:
Picture 28. Information of the memory of the top. 1
Picture 29. Information of the shears in manual mode.
Once the cutting sheet is introduced, press the pedal for the blade to go down In the manual mode, the
blade goes down while you keep the pedal pressed down, in such a way that if you loose it, then the blade
changes its movement the other way around and starts going up until it reaches the upper rest position.
Then once we get to know this performance principle, if a sheet need to be cut, the user has to press the
pedal until the blade reaches the lower position of its vertical route. Once it is there and therefore it has cut
the sheet, it won’t go up again until you stop pressing the pedal. If you do it the shears blade will start
moving until it reaches the upper rest position.
You have to know also that if you press the pedal while the blade is going up, the blade will invert its
movement and will go down again.
On the other hand and as a remarkable point, you must be conscious that every time you press the pedal
to make one cutting operation, it will automatically increase the cutting meters associated to the memory of
the top that is performing. This will show in the following picture:
Picture 30. The memory meter of top 1 has been increased
Therefore, if the pedal is pressed several times to make a cutting operation, the couter meter will increase
the same number twice, since te machine will take for granted that you have made all those cuts. This kind
of performance is based in the need to count all the times the pedal has been pressed, because several
times the machine’s rented to other people and the rental price depends on the number of cuts made. So
the operative will make a reasonable use of it, since the more times he presses the pedal to make the
same number of cuts of sheet, the more expensive the rental will be.
