Transport shall be carried out by qualied personnel so as to avoid any damage to the machine and any of its
components. In particular:
• All the guards, covers and doors must be properly closed and secured.
• Use a forklift or transpallet with su󰀩ciently long forks and loading capacity.
The load bearing capacity of the forklift truck must be more than the weight of the machine; check this
capacity on the plates a󰀩xed on the forklift truck and in the operating instructions.
The machine should be transported on a at and solid oor only, free of unevenness.
INSTALLATION
The machine must be positioned on a hard and level oor. Connection to the power supply must be carried out
in accordance with the current standards and taking into account the necessary measures in order to avoid the
dangers of indirect contact and overcurrent. Also check that:
• The supply voltage is 400 V on the input terminals (L1 - L2 - L3) located inside the electrical control panel.
• The machine’s connection to ground is, in fact, connected to the company grounding system.
Make sure the cutter is placed in a su󰀩ciently lit work area (min. 300 lux). Check that there is enough space
around the machine to move the removable parts and that it is easily accessible for routine and extraordinary
maintenance (at least 500 mm of free space besides the dimensions of removable parts)
PRELIMINARY CHECK PRIOR TO STARTING-UP
Once the machine has been connected to the mains the following check is necessary:
1. Using the jog mode, press the two hand control device (push buttons P), to check that the cutting wire
moves down towards the work top.
2. If the wire moves upwards instead, reverse the electrical connections in the plug (reverse the phase).
3. Now check again.
If it is necessary to reverse the phase you must rst disconnect the electricity (take the plug out of the
socket/open the omnipolar switch directly upstream). In all cases this must be done by a specically
skilled electrician.
The machine is equipped for the earth-connection of conductive metal masses. The connection must
be ensured and carried out correctly in accordance with applicable technical standards. The machine
cannot be used if it is not earthed.
Operations on electrical equipment must only be carried out by qualied technical personnel with
the necessary electrical engineering skills, after referring to the wiring diagram and the necessary
conditions in order to avoid electrocution.

MOVABLE GUARDS
The guards can consist of a part of the machine specically used to provide protection through a physical
barrier. Depending on its construction, a guard can be called a casing, cover, screen, etc.
INTERLOCKING GUARDS
The interlocking guards are equipped with position sensors that detect whether the guard is open/close and
cause dangerous moving parts to stop (interlocking device) when the guards are opened. Opening the guards
prevents the dangerous moving parts from restarting. The following are considered interlocking guards:
1. The left-hand hinged door to access the area underneath (motor).
2. The right-hand hinged door to access the area underneath (motor).
Do not remove or force the interlocking guards’ position sensors as this may cause the safety devices
to malfunction leading to dangerous situations.
Regularly check the correct functioning of the interlocking devices. When the guard is open, the
machine must not start.
FIXED GUARDS
The xed guards are considered as such when they feature xing elements which can only be removed by
using a tool.
The rear and sides of the machine are closed with xed guards in either a transparent material or metal
Before removing the xed guard, the protected areas must be secured by switching o󰀨 the power from
the control panels to stop any movement. Replace the guards that have been removed before leaving
the workplace or before resuming work.
TWO-HAND CONTROL DEVICE
Descent of the cutting wire is controlled by a two-hand device. These push buttons must be pressed
simultaneously within a maximum time of 0.5 seconds. If you fail to press them within this time, release both
push buttons and do it again.
Periodically check that the two-hand control device is working properly (see the maintenance and
periodical checks paragraph)
EMERGENCY STOP
Emergency stop is located:
• At the front, between the two-hand control push buttons.
The emergency stop push button is equipped with a self-retaining device (once pushed it remains locked in
the open circuit position) that needs to be deliberately reset by an operator after being pushed. Pushing the
emergency button will stop all the machine’s moving parts.
