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

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.

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 installation 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.

The surfaces of components can become very hot during operation. Direct contact with hot
surfaces causes severe skin burns.
– Do no touch hot surfaces during operation, wear protective gloves if necessary.
– Ensure that all surfaces have sufficiently cooled down prior to starting any work.
WARNING!
Sound pressure level
Depending on the operating conditions, the sound pressure of the device may cause hearing
damage.
Take suitable action to reduce the impact of the existing sound pressure level. The owner is
responsible for the type and implementation of suitable measures, which may depend on the
local conditions.
7.2 General information about initial start-up / commissioning
Adhere to the following general information for initial start-up / commissioning:
n Only carry out the commissioning of the automatic spray gun pursuant to the steps described
in this operating manual.
n Check the material and compressed air hose lines for damage and tight fit before each use.
n Always observe the applicable country-specific safety, accident prevention, occupational
safety, and environmental protection regulations etc. for the area of use for the automatic
spray gun.
n Do not use sharply abrasive, chemically aggressive, very hot or very cold spray media without
first consulting and receiving approval from Krautzberger GmbH.
n Adhere to the spray media manufacturer's safety data sheets.
n Only operate the automatic spray gun while adhering to the values specified in (

7.3 Shutting down
7.3.1 Temporary shut-down
1. End the spray process by switching off the material supply.
2. Switch off the atomiser air (connection “Z”).
7.3.2 Long-term shut-down
1. End the spray process by switching off the material supply.
2. Switch off the atomiser air (connection “Z”).
3.
If necessary, clean the automatic spray gun (
Ä
Chapter 8.3 ‘Cleaning’ on page 25).
7.4 Commissioning
1. Point the automatic spray gun at a test surface.
2. Switch on the atomiser air (connection “Z”).
3. Begin the spray process by switching on the material supply.
4.
Adjust the spray pattern ( Ä Chapter 7.5 ‘Adjusting the spray pattern’ on page 22).
6. End the spray process by switching off the material supply.
7. Switch off the atomiser air (connection “Z”).
8. Direct the automatic spray gun towards the workpiece to be coated.
9. Switch on the atomiser air (connection “Z”).
10. Begin the spray process by switching on the material supply.
7.5 Adjusting the spray pattern
Air and material nozzles are available in various sizes. There are 4 different families:
n Round jet – cone-shaped jet in front of the nozzle.
n Flat jet – width-adjustable jet for flat-shaped application.
n Rotary jet – a rotary pulse produces a highly "swirled" spray jet; for difficult work piece geo-
metries (angular sections etc.).
n Full-cone rotary jet – a rotary pulse produces a highly "swirled" spray jet; for difficult work
piece geometries (back cuts, etc.).
The spray pattern can be adjusted with the following measures:
n Change the atomiser air pressure.
n Change the pressure of the spray medium.
n Select another nozzle size.
mail@krautzberger.com, www.krautzberger.com GB–22
Automatic spray gun MC1
ENGLISH
Too-high air pressure causes unnecessarily high air consumption and too-strong atomisation
of the spray medium. It is recommended that you first adjust the spray pattern by varying the
air and spray medium pressure. If you cannot achieve satisfactory results this way, you should
experiment with other nozzle sizes.
