Discharging is done automatically by the machine
each time the power is switched off. However, you
must allow the machine to sit for at least 5 minutes
to allow time for the process to take place.

ation fins and over them.
Carry out the following periodic controls on the power

pressure compressed air.
• Check the electric connections and all the connec-
tion cables.
• Always use gloves in compliance with the safety
standards.
