1.2 Short description
The spray gun is intended for surface
coating. Compressed air is used to apply
material. The material to be atomized is fed
via flow cups. The spray gun is handheld.
Use a suitable nozzle set with air cap,
depending on the requirement Ä 6.3
“Selecting air cap”.
The following factors influence the spray jet
and the result:
Alignment of the air cap Ä 6.5 “Alignment
of the air cap”
Material flow Ä 5 “Commissioning”
Air pressure Ä 5 “Commissioning”
Horn air pressure Ä 5 “Commissioning”
The spray gun uses a self-adjusting needle
package. The needle gland automatically
adjusts for the material-related wear of the
needle gland. In addition, the needle packing
can be readjusted mechanically.

Setting the material flow
Fig. 3: Setting the material flow
1. Set the material flow.
Turn material flow control (1) in
required direction.
Right turn: less material
Left turn: more material
Do not turn material flow control
to the right up to the mechanical
stop. The needle can then no
longer move properly.
To reduce the material quantity,
preferably use a smaller nozzle
set and not the material quantity
control.
To increase the material quantity,
preferably use a larger nozzle set.
Set total air pressure
Fig. 4: Setting the total air and horn air pres-
sure
2. Set the total air pressure by turning the
total air control (2).
Right turn: Lower total air pressure
Left turn: higher total air pressure
Observe the following character-
istic curve.
Setting the horn air pressure
3. Set the horn air pressure by turning the
flat jet control (1).
Right turn: rounder spray pattern
Left turn: flatter spray pattern
You can turn the flat jet control
continuously and adjust the spray
pattern from flat to round jet.

6 Operation
6.1 Safety recommendations
WARNING!
Danger of explosion due to chemical
reactions
Material, halogenated hydrocarbon-based
rinsing agent or cleaning agent can chemi-
cally react with aluminum components of
the product. Chemical reactions can
cause explosions. Serious injuries and
death can be the consequence.
– Only use rinsing agents and cleaning
agents that do not contain any halo-
genated hydrocarbons.
NOTICE!
Material damage due to dried material
residues
If material residues dry in the product, that
can harm components.
– Rinse product immediately after each
use.
6.2 Checks
1. Perform the following checks during oper-
ation:
Check air connection for correct seat
and leaks.
Check air car for cleanliness.
Check nozzle for cleanliness.
6.3 Selecting air cap
You can convert the spray gun for various
uses by swapping the air cap.
Air cap AL
The air cap AL is used for solvent-based
coating materials (1-component paints and
2-component paints) and water-based ones.
It is used for application of fillers, basecoats
and topcoats. If used with a hardened
nozzle, coating materials with abrasive addi-
tives (coating materials containing zinc and
aluminum) can be applied.
Air cap EL
The air cap EL is used for solvent-based
coating materials (1-component paints and
2-component paints) and water-based ones,
if higher outflow rates are required.
Air cap GL
The air cap GL is used for thick, high vis-
cosity coating materials. It is used for appli-
cation at a high outflow rate.
