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 condi-
tions.
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 prin-
ciple 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.

6.3 Installing the automatic spray gun
Changing the installation position of the automatic spray gun
The automatic spray gun can be mounted on both sides on the retaining bolts in order to
change the installation position.
Fig. 2: Installing the automatic spray gun
1. Slide the automatic spray gun ( Fig. 2/1) with the intended drill hole over the retaining bolt (
Fig. 2/2).
2. Fix the retaining bolt in place on the underside of the automatic spray gun using the instal-
lation screws ( Fig. 2/3).
3. Ensure proper grounding of the automatic spray gun.
6.4 Connecting the automatic spray gun
WARNING!
Danger of injury due to improper connection!
When the material supply is pressurised, e.g. from pressure containers or with pumps, the
range of the material jet can increase by a multiple in case of atomizer air failure. This
presents a hazard to people and property.
– Make sure that the material supply is interrupted if the atomizer air pressure drops off
quickly.
– It is recommended to regulate the atomizer air pressure via a filter pressure reducer.
The connections for the material input and for the atomiser air are marked with letter codes.
