If the pressure of the bearing air is not sufficient, there is the risk that
the shaft will suddenly seize.
In that case, a firm grip of the bell disk on the shaft is not guaranteed.
A flying bell disk puts at risk life and limb.
The pressure of the bearing air must not exceed the "operating
parameters" indicated above.

Commissioning
The atomizer is part of an electrostatic spray system. Only when all
required components are installed, the entire system can be put into
operation.
The painting process is monitored by a higher-level control system
and runs fully automatically. The painting process can be started via a
user interface.
6.4.3
Testing the paint flow control (volumetric measurement)
The quality of the paint flow control must be tested prior to
commissioning and at reasonable intervals and, if necessary,
calibrated. This process is referred to as "volumetric measurement."
To measure is the predetermined target amount compared with the
actual amount currently flowing from the nozzle.
For this test, a calibrated vessel and the adapter of the atomizer are
needed. The adapter (volumetric measurement tool) is absolutely
necessary to prevent pollution at the shaft end of the turbine.

Danger due to escaping material
Material can get into eyes.
Wear safety glasses.
Prerequisites:
- The shaft of the turbine may not turn.
- The bell disk must be removed from the atomizer.
- Keep the nozzle mounted on the atomizer.
- Only use the original adapter.
- The container to collect the paint must be sufficiently large and
have a secure stand.
