Operator’s manual
- The user must:
• fit a plug that respects the current regulations onto the power supply cable;
• connect the machine to its own electrical connection fitted with a suitable 30-mA current
sensitive circuit breaker;
• fit power supply protection fuses sized in compliance with specifications in the main
wiring diagram of this manual;
• provide the workshop electric installation with an efficient grounding circuit.
- Prevent unauthorised use of the machine, always disconnect the power supply plug when
the machine is not used (switched off) for extended periods of time.
- If the machine is connected directly to the power supply by means of the main electrical
board and without the use of a plug, install a key-operated switch or suitable lock-out device
to restrict machine use exclusively to qualified personnel.
CAUTION
For the machine correct functioning it is vital to have a good ground connection. NEVER
connect the machine ground wire to a gas pipe, water pipe, telephone cable or any other
unsuitable object.
COMPRESSED AIR HOOK-UP
WARNING
The compressed air hook-up may only be performed if the pneumatic ring nut is sup-
plied (optional accessory supplied on request).
CAUTION
All compressed air hook-ups must be carried out by qualified personnel only.
- The hook-up to the workshop compressed air system must ensure a minimum pressure
of 8 bar.
- A universal union is used for connection to the compressed air system. No special or
additional adaptor is needed for connection. A pressure-resistant hose with 6mm inner
diameter and 14mm outer diameter must be fastened to the notched union using the
clamp provided with the machine.
