-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.

Provide compressed air through a tube with a minimum interior diameter of 8 mm., connected to
the intake.
NOTE:
One must bear in mind that the air consumption of this punch cutter is 280 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.
-Description:

WARNING:
HAND AND ARM TRAPPING HAZARD WITH THIS DEVICE DUE TO THE MOVEMENT OF THE
CUTTING HEAD. GREAT CARE MUST ALSO BE TAKEN BETWEEN THE CUTTING HEAD AND
SUPPORT PLATE, AS THERE IS THE DANGER OF LIMBS BEING SEVERED.
Once the machine electrical and air connections are made, proceed to start it up using the ON
switch.
Check that the regulator pressure is between 2 and 6 bar according to the cutting head installed.
Safety Systems and messages.
This punch cutter has been equipped with the following safety systems:

2. 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 LOCK PUSH BUTTON
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: TREAD BAR
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: DOOR 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: CYLINDER DETECTOR
To deactivate it, provide the machine with air or replace the detector.
Programming.
We must know the functions of the push buttons on the board to program the punch 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 most cases, to always operate on guide rail and cut the belts
performing the first end by inserting it on one side of the bridge and the second end on the
other side, or to cut series continuously.
3. A-B
Selection of the A-B program to do individual operations.
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.
6. MENU
This button is to jump from one programming field to another and thus amend the values:
Belt width
Step
Cutting time
7. + / -
To increase or decrease the marked field values.
8. OK
To validate the modified value. Any modification must always be validated.

Changing punch
WARNING:
When changing punches, switching off the equipment at the OFF switch is recommended
for greater safety.
Open the sliding door.
Loosen the 2 bolds using a 13mm. spanner.
Take out the punch and insert the new one.

Retighten the 2 bolts.
Close the sliding door and program the correct step in the MENU …. STEP … OK
NOTE:
The cutting pressure must be adjusted for each type of punch or material.
If not, excess pressure may cause the blades to break or premature wear of the cutting
aluminium board.
PUNCH CUTTING A-A direct finger:
Write with pencil a line at 100mm approx. from the beginning of the belt.
Take this line like 0 of total length of final endless measure.

Remove the plate from the back side of the frame.
Maintenance and care:
•Keep the screw and linear guides dust free and well lubricated with low density, low
silicone content lubricant oil.
•Replace the blades or the polypropylene bench when imperfect cuts are observed.
•Periodically move the polypropylene base 2 or 3 mm. to even out the wear.
•Empty out the water and clean the air intake filter basin if there is condensation in the line.
-Troubleshooting:
The board does not turn on.
Check whether the switch LED turns red to determine a possible problem in the electric power
line to the machine.
The head does not move at all.
Check that the cylinder is upward and that the grid (cylinder cutting detector) is on.
The head moves but does not cut.
Check that the electro-valve is working and that the connector LED is on.
Check that the regulator pressure is above 2 bar.
Check that the cutting time is programmed between 05 and 10.

The belt is not cut across the full width.
Check that the intake pressure does not drop during cutting due to compressed air supply
shortage.
Check the thickness of the polypropylene plate.
