Adjust the powder quantity and the powder speed on a test piece.
3.2
Switching off the spray gun
Hint
On each interruption to work, the spray gun should be blown through (purged) and
powder residue removed. In this way
powder deposits
and a
surge
the next time the
spray gun is switched on can be largely avoided.
Switch off the powder coating plant after automatic purging and secure it against
inadvertent switch on.
3.3
Performing a color change

During a color change all parts carrying powder
must
be
thoroughly
cleaned of powder
residue. In the following only the procedure for the powder spray gun is described.
Hint
During a color change, the nozzle system does not necessarily have to disassemble.
Caution
If the outer nut is not screwed on tightly up to the stop position, the colors may smear.
Switch off the powder coating plant after automatic purging and secure it against
inadvertent switch on.
