2) WARNINGS, PRECAUTIONS AND
GENERAL NOTICES FOR PERFORMING REPAIRS
Repairs must be performed by qualified personnel only.
Before performing the repair, you should read and assimilate the
contents of this manual, in particular the safety precautions.
Avoid performing repairs without the presence of another person
able to provide help in the event of an accident.
The repair of a machine requires access to its internal parts and con-
sequently removal of some of the protective panels. Additional pre-
cautions are therefore necessary with respect to use of the machine
for welding in order to prevent possible injury or damage caused by
contact with
- live parts
- moving parts
- parts at high temperature
CAUTION
LIVE PARTS
When handling internal parts of the machine, remember that ope-
ning of the switch does not prevent the risk of electric shocks: the
machine must be unplugged from the power supply.
Wait approx. one minute before carrying out work on the internal
parts as the capacitors may be loaded at high voltage.
CAUTION
LIVE PARTS OF THE TOOLS
When taking measurements, remember that the measuring instru-
ments can be live and you should therefore avoid touching their
metal parts
CAUTION
MOVING PARTS
Keep your hands well away from the fan when the machine is con-
nected to the power supply. Ensure that the machine is unplugged
and that the fan is at a standstill before replacing it.
CAUTION
PARTS AT HIGH TEMPERATURE
When handling internal parts of the machine, remember that some of
them may be very hot. In particular avoid contact with heat sinks.
