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.

ENGLISH
1 Function and identification
1.1 Function
For steam spray guns, the compressed air that is ordinarily required for the atomisation process at
the nozzle is replaced by steam. This process uses a steam generator to generate pressure. The
control of the steam spray gun is still carried out via compressed air, which is generated by compressors.
Steam spray guns are used for the following applications:
n Automatic coating of surfaces
Especially spray fluids such as lacquers, paints, adhesives, glazing, enamel, debonding agents
and other processing aids are used with this technique.
The geometry of the spray jet and the quantity of the spray fluid to be applied can be changed by
adjusting the following factors:
n Selection of the air and fluid nozzle
n Changing the atomising steam pressure
n Changing the spray fluid pressure
n Adjustment of the needle stroke at the control of the steam spray gun (option)
n Changing the round and flat jet
The steam spray gun can be operated both as an independent device as well as in a larger system
(as a component of a fully-automatic coating system as well as a spray robot).

3 Safety and responsibility
3.1 General safety instructions
WARNING!
Risk of death, risk of injury or property damage due to hazardous media!
Potential consequences: The application of hazardous media can lead to death, severe injuries or property damage.
When handling hazardous substances, ensure that the current safety data sheets of the hazardous substance manufacturer are available. The necessary measures can be derived from
the content of the safety data sheet. Since the hazardous potential of a material may be reassessed at any time due to new lessons learned, the safety data sheet must be checked regularly and replaced if necessary.
The system owner is responsible for the presence and the up-to-date status of the safety data
sheet and the associated generation of the risk assessment of the effected workstations.
CAUTION!
Risk of injury due to the discharge of hot steam!
Exiting steam can reach high temperatures. Direct contact with expelled hot media can cause
scalding of the skin.
Note:
– Switch off steam generator and wait until the system has cooled down prior to working on
the steam spray gun.
– The steam pressure line of the steam spray gun can be under pressure and must be
closed if necessary.
– Do not direct the steam jet at people.
CAUTION!
Risk of injury from compressed air!
During the work on the steam spray gun, compressed air may exit and thereby cause injuries.
– Switch off compressor prior to any work on the steam spray gun.
– The pressure line of the steam spray gun can be under pressure and must be vented if
necessary.
