-Transport and unloading the machine:
Due to the fragility of some components of the machine, wood packaging is required with
reinforced board to attach it to the base by bolts through the openings in the rubber feet.
To keep the weight of the load well balanced, moving the punch cutting head to halfway across its
run before proceeding to pack is recommended.
For sea transport, the linear rails and drive screw located at the bottom of the cutting head must
be lubricated and full plastic cover provided.
A pallet truck must be used to move the machine, lifting it by the bottom cross bars of the bench
just as shown in the picture.
Fit the four rubber feet and proceed to level.

WARNING: Avoid the entry of air with humidity or condensation. For this, it is
recommended to use a compressor with a drying unit.
NOTE: While the compressed air is connected, we will hear a slight air leak coming from the
pressure regulator. This is not an abnormality.
NOTE:
One must bear in mind that the air consumption of this punch cutter is 220 litres/minute.
Connect the power cable to the control board at 230v monophasic.
NOTE:
It is recommendable for the air and power lines to be run from above to prevent the staff
tripping or falling.

Safety systems and messages
This die cutter has been equipped with the following safety systems:
1- EMERGENCY STOP
This system allows an emergency stop to be performed at any time using the two push buttons
located at both ends of the bench.
MESSAGE: EMERGENCY BUTTON PRESSED
To deactivate it, we must unlock the push button and then press RESET to return the head to the
starting point.
2- TREAD BAR
This device does not allow engagement of the cutting head if the bar holding the belt is not
lowered.
MESSAGE: CLAMP OPEN
To deactivate it, all one need do is lower the bar and press START.
3- DOOR OPEN
This device detects that the rear door of the blade head is open.
MESSAGE: COVER OPEN
The door must be closed to deactivate it.
4- CYLINDER DETECTOR
This device does not allow displacement of the head because it detects that the cutting
cylinder is not raised. This may happen due to lack of air or failure of the detector.
MESSAGE: CYLINDRE WRONG
To deactivate it, provide the machine with air or replace the detector.
1. CYLINDER DETECTOR
This device does not allow displacement of the head because it detects that the cutting cylinder is
not raised. This may happen due to lack of air or failure of the detector.
Message: CYLINDER DETECTOR

Programming:
We must know the functions of the push buttons on the board to program the die cutter.
1. RESET
This must be pressed after an emergency stop or position the head at the starting point
after STOP.
2. A-A
Selection of the A-A program
This program is used in the majority of cases, to always operate on the left guide rail and
cut the belts performing the first end with the coverage on top and the second end with
the fabric on top, both for direct finger die cutting as well as finger over finger die cutting.
3. A-B
Selection of the A-B program
This program is only used in cases of diagonal belts, or belts with an hi profile, to operate
the first end on the left guide rail and the second on the right guide rail, always with the
coverage on top.
4. STOP
Allows the cutting process to be halted at any moment, to change the time or cutting
pressure, for example.
On pressing START, it will continue the process without losing the positioning memory
5. START
Starts the cutting process or acts to reboot following a STOP.

NOTE:
This type of punch cutting requires prior separation of the cloths using the PS-15
separation device
Separate the cloths of the belt 130 mm. at both ends.
Fit 50x20 mm. punch.
Check that the A-B function is activated.
Program STEP 20 mm. and the required width in centimeters.
Adjust the pressure to 2 bar, as the cutting surface is less due to the blade length.
NOTE:
To perform finger on finger cutting, the two ends of the belt must be done on the same side
of the machine. The A-B program changes the step progress every two operations.
Place the first end of the belt next to the guide and position the end of the belt just by the Ref. 0
mark.
Then mark the two material insert measures for STEP-1 and STEP-2 in pencil.
After making the two marks (STEP-1 and STEP-2) place the cut-proof plate between the previously
separated cloths, so it comes out on both sides.
