8 MAINTENANCE

Routine maintenance must be carried out on the system accor-
ding to the manufacturer's directions.
Any maintenance operation must be performed by qualified
personnel only.
When the equipment is working, all the access and operating
doors and covers must be closed and fixed.
No type of modification must be made to the system.
Prevent metal powder from accumulating near the aeration fins
and over them.
Disconnect the power supply before every operation!
Carry out the following periodic controls on the
power source:
* Clean the power source inside by means of low-
pressure compressed air and soft bristel brushes.
* Check the electric connections and all the connec-
tion cables.
For the maintenance or replacement of torch
component, electrode holder and/or earth cables:
* Check the temperature of the component and make
sure that they are not overheated.
* Always use gloves in compliance with the safety stan-
dards.
* Use suitable spanners and tools.
Failure to perform said maintenance will invalidate all war-
ranties and exempt the manufacturer from all liability.
