Setting the spray pattern
NOTICE!
Wrong handling of the material flow
control
If the material quantity is set using the
material flow control, it must not be used
for closing the material nozzle. Otherwise,
cracks and fractures can occur on the
material nozzle, ultimately leading to the
failure of the spray gun.
– Do not use the material flow control for
closing the nozzle.
– Close the material flow control by
turning it only with slight force (two fin-
gers). Do not continue turning it if
resistance is increasing.

You can adjust the spray pattern continu-
ously between round and flat, by using horn
air.
You can vary the size of the spray
pattern by adjusting the distance
between the spray gun and the work
piece.
