Comment: Before checking the speed, the distance between the control air ring and the bell
disk is to be checked.
The distance between the outer edge of the bell disk
and control air ring (1) must be checked with the test
tool W02020284. The information about the surface to
be used for a certain sprayer gun type is engraved on
the testing tool.
