Information about the operating manual
This manual provides important information on how to work with the device safely and efficiently.
The manual is part of the device and must always be kept in the immediate proximity of the device
so that it is accessible to the personnel at all times.
The personnel must have read and understood this manual before starting any work. Compliance
with all specified safety information and instructions is a basic requirement for safe working conditions.
In addition, the local occupational safety regulations and general safety rules apply for the area of
application of the device.
Due to optional finishing variants, it is possible that the figures shown in this operating manual
deviate from your device.
Information about explosion protection
Many of our competitors have been marking their products with the Ex symbol as a matter of principle for some time now.
At Krautzberger we do not do that.
We engineer and manufacture our products in line with currently applicable directives.
If the labelling on the product is required, it is affixed to the product as the result of the necessary
analysis of ignition sources. If no labelling is affixed, the analysis of ignition sources and previous
experience with the assessment of the suitability of products for use in a potentially explosive area
have shown that the product described in this operating manual does not represent a potential
source of ignition, with the exception of an electrostatic charge.
Taking into account the potential equalisation (provided by proper earth connection), the use in an
area at risk for explosions is permitted in accordance with the currently valid directives.

1 Function and identification
1.1 Function
Automatic spray guns are used for
n automatic coating/marking of surfaces
n Dosing of fluids
n Placement of adhesive or marking points
Typical spray media are paints, dyes, adhesives, glazes, enamels, release agents, etc.
The spray medium is fed into the automatic spray gun under pressure. The pressure is typically
generated by pumps or pressure containers. The automatic spray gun is controlled via compressed air.
For precision control of the automatic spray gun, electrically-activated solenoid valves can be
used.
The spray medium is atomised using compressed air. The geometry of the spray jet and the
sprayed quantity of the spray medium can be adjusted using the following measures:
n Selection of air and material nozzle
n Change of atomiser air pressure
n Changing the spray medium pressure
n Adjustment of the needle stroke on the regulator of the automatic spray gun
Optional equipment:
Automatic spray gun:
n Main element (stainless steel or aluminium, chemically nickel-plated, PTFE-coated)
n Needle stroke adjustment
n Circulation connection
n Double controller (interruption of the material supply through spring force or pneumatically)
n Nozzle fixing (
Adapter:
n Connections: From below or behind (the connections can be made using nipples, screw-type
or plug connectors of different sizes)
n Fastening: Clamp or screw-type fastening of the adapter
