9.2. Normal operation
The automatic gun has an internal
control. The control air triggers
the control pulse and opens the
spraying air valve of the automatic
gun, thus ensuring that pressurised
spraying air is always present at the
automatic gun.
Before using the automatic gun,
heed/check the following points to
warrant safe working with the gun:
■ Automatic gun is safely fitted.
■ Compressed air flow rate and pres-
sure is ensured.
■ Clean compressed air is being used.
Connect the material supply
Note!
Only unscrew the gravity flow
cup when drained to prevent any
material from leaking.
A gravity flow cup is responsible for
material supply to the automatic gun.
■ Screw the gravity flow cup onto the

gravity flow cup connection piece.
■ Unscrew the screw-on lid.
■ Fill the gravity flow cup.

Adjust spray gun inlet pressure
Note!
If the gun input pressure does
not reach the necessary level,
increase the pressure in the com-
pressed air circuit.
■ Adjust the spraying air to the neces-
sary input pressure.
Adjust the material flow
Attention!
The grub screw [4-1] is glued
firmly in the material flow control
and is used for fixing the unit.
The needle lifts 1.0 mm per turn
of the material flow control and
0.04 mm per grid unit.
The adjustable scale ring [1-3]
and the scale on the gun body
[1-13] help with adjusting the set-
tings and for reproduction of the
material flow. The scale ring can
be fixed in the required position
with the fixing screw [1-10].
The material flow is adjusted as follows:
■ Screw in the material flow control as
far as it will go.
■ Adjust the scale ring to zero and fix
with the fixing screw. Adjust the scale
ring left-aligned with the smallest
