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.
•
If you do not use automatic purging, flush the powder spray gun manually and clear any
residues of powder before you shut down the plant:
Disconnect the powder hose from the spray gun.
-
Clear the spray gun using the air gun and clear any residues of powder.
-
- Shut down the plant and secure it against inadvertent switch on.

Before you commence to connect the powder hose again, all parts carrying powder must
be thoroughly cleaned.
The spray gun is ready for use again.
