Translation of the original operating instructions
Thank you for selecting a Krautzberger product.
This product has been manufactured following state-of-the-art manufacturing procedures and
extensive quality assurance measures. We promise you a product of the highest quality.
If you have questions, requests or suggestions, please contact us. We are always glad to assist

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.

Automatic spray gun M -10
ENGLISH
1 Function and identification
1.1 Function
Automatic spray guns are used for the
n automatic coating/marking of surfaces
n dosing of fluids
n placement of adhesive or marking points
Typical spray fluids are paints, dyes, adhesives, glazes, enamels, debonding agents, etc.
The spray fluid is fed into the automatic spray gun under pressure. This pressure is typically generated by pumps or pressure containers. The automatic spray gun is controlled via compressed air.
For the precise control of the automatic spray gun, electrically-activated solenoid valves can be
used, for example. Switching times of 60 ms can be achieved this way.
Upon opening the control, the control piston charged with compressed air first opens the atomizer
air valve and then with a short delay the fluid nozzle of the spray gun. Upon closing the control,
first the fluid nozzle and then the air nozzle is closed in order to prevent a subsequent dripping of
the spray fluid.
The spray fluid is atomised using compressed air. The geometry of the spray jet and the sprayed
quantity of the spray fluid can be adjusted with the following measures:
n Selection of the air and fluid nozzle
n Changing of the atomisation air pressure
n Changing of the spray fluid pressure
n Adjustment of the needle stroke on the regulator of the automatic spray gun
The automatic spray gun consists of the following materials:
Component Material
Head section Stainless steel or anodised aluminium
Control section Aluminium anodised
Main element
Needle Stainless steel
Nozzle
Seals Various plastics
