Maintenance
IMPORTANT: The machine is to undergo routine maintenance,
as suggested by the manufacturer.
ATTENTION: Cut off the power supply to the equipment be-
fore effecting any internal inspection.
SPARE PARTS
Original spares have been specifically designed for our equip-
ment.
The use of spares that are not original may cause variations
in the performance and reduce the safety level of the equip-
ment. We are not liable for damage due to use of spare parts
that are not original.
THE EQUIPMENT
As these systems are completely static except for the fan that
is, in any case, provided with self-lubricating bushes, only the
following operations are necessary:
• Periodic removal of accumulations of dirt and dust inside the
equipment using compressed air. Do not direct the air jet di-
rectly to electrical components that could be damaged.
• Periodical inspection for worn cables or loose connections
that could cause overheating.
• Make sure the air circuit is completely free of any impurities
and that the connections are tight and free of any leaks. In
this regard, particular attention must be given to the solenoid
valve and the air filter.
• Although the air filters do not have an automatic condensate
drain, it is good practice to clean the air filter insert from time
to time (Fig. R).
CARRYING OUT ROUTINE MAINTENANCE
WARNING: Disconnect the electricity supply before doing
maintenance work. All tasks that call for the generator’s cover
to be removed, must be done by a qualified technician.
Each time you use the machine:
• Check the indication LEDs and fault icons. Correct any faulty
condition.
• Check that the consumables are fitted correctly and are not
worn.
Every 3 months:
• Inspect the power supply cable and plug. Replace if dam-
aged.
• Check that the button is not damaged. Check that the torch
grip is not cracked and there are no exposed wires. Replace
any damaged component.
• Inspect the torch cable. Replace if damaged.
Every 6 months:
• Periodic removal of accumulations of dirt and dust inside the
equipment using compressed air. Do not direct the air jet di-
rectly to electrical components that could be damaged.

Replace the diffuser
ring if the surface is
damaged or worn,
or if the air holes are
obstructed.

electrode if the
surface is worn or the
depth of the crater is
more than 1,6 mm.

Roundness of the
central hole.
Replace the nozzle if
the central hole is not
round.
