Routine Cleaning

It is not always necessary to dismantle the spray gun for cleaning purposes when
paint colour is changed at regular intervals or at the end of a work period (depending,
of course, on the material used). The PTFE-coated gun body may be cleaned with a
cloth.
For routine cleaning purposes please observe the following steps:
1. Fill the clean material pressure tanks with a cleaning solution compatible with the
material used.
2. Start the spray gun (see 5.2 Requirements at the Start and Finish of Operation).
3. Do not stop the gun until only clear cleaning solution emerges from the nozzle.
The complete spraying system should stay depressurised until the gun is used again.

Troubleshooting

Warning
Prior to any servicing and repair work the spray gun should be in unpressurised state,
i.e. all control air and atomizing air pressure as well as all material inputs must be shut
off - risk of injury.

Disposal of Cleaning and Servicing Substances

The disposal of substances used for cleaning and servicing should be in
accordance with local, national and international laws and directives.
Warning
Particular attention should be paid to the spray and cleaning media manufacturers'
instructions. Improper disposal represents a serious threat to the health of humans
and animals.
