Risk of property damage and production disruption
In case of wrong assembly, shaping air ring and bell disk can rub
against each other. Shaping air ring and bell disk can be damaged.
Check the distance between shaping air ring and bell disk. The bell
disk should not rub against the shaping air ring.
If the bell disk rubs against the shaping air ring, atomizer body,
shaping air ring and bell disk should be disassembled and
reassembled.
Then check the distance again.
The atomizer must not be operated with a rubbing bell disk.
Finally, the following work should be executed:
- Clean the entire atomizer by hand with isopropyl alcohol.
- Check that the atomizer is assembled completely.
- Ensure that there are no loose objects (tools, spare parts, cloths) in
the cabin.
- Rinse the atomizer.
Only then the atomizer should be used.
