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.

Depending on the nozzle set used, you can
influence the spray pattern through various
factors.
You can set the spray pattern for any pat-
tern between round and flat by using a
flat jet nozzle set, by using horn air. You
can vary the size by adjusting the dis-
tance between the spray gun and the
work piece.

can vary the size by adjusting the dis-
tance between the spray gun and the
work piece and the screw depth of the air
cap. The size of droplets of the medium
to be applied can be influenced through
the screw depth of the air cap.

cabinet or at material flow control (3).
Open the material flow control on
the spray gun when controlling
via the regulation cabinet.
2. Set atomizer air using valves in the con-
trol cabinet or on the atomizer air control
(R) (1).
Observe the following character-
istic curve.
3. Set horn air using the horn air control (F)
(2) or using valves in the control cabinet.
When using a round jet nozzle or
rotary jet nozzle, close the horn
air control.
