3.7 MAINTENANCE AND CONTROL

It is recommended to keep nozzle free from slag. Avoid using
sharpened bodies thus avoiding damaging the nozzle hole. Even
if the unit is provided with an automatic device for water
discharge, working whenever air feed is closed, it is
recommended to check from time to time that no water remains
in trap I of reducer. It is required to clean from time to time the
unit inside and make it free from metal dust by means of
compressed air. Operations to be carried out inside the unit must
be effected after disconnecting feed cable.
3.7.1. PRECAUTIONS TO TAKE AFTER A REPAIR
After making repairs, take care to re-order the cables so that
there is sure to be insulation between the primary and the
secondary sides of the machine. Make sure that the wires cannot
come into contact with moving parts or parts that heat during
operation. Replace all clamps in their original positions on the
machine, to prevent a connection between the primary and
secondary circuits if a conductor accidentally breaks or
disconnects.
