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.

1 Function and identification
1.1 Function
Hand-held spray guns are used for the
nCoating/marking of surfaces
nDosing of fluids
nPlacement of adhesive or marking points
The fluid medium is fed into the hand-held spray gun via
nPumps, pressure or pressure-drop containers
nScrewed-on gravity feed cups or suction cups
If small quantities of a fluid are processed, the use of fluid or suction containers is recom-
mended. Suction containers should only be used with low-viscosity fluids. With regard to suc-
tion operation, the air consumption of the hand-held spray gun is higher as the spray medium
is conveyed against the force of gravity.
Depending on the customer configuration, the hand-held spray gun HS 30 can be fitted with the
HV nozzle system. This is an HVLP system (hvlp = high volume, low pressure) for low-mist
coating.
The spray medium is atomized using compressed air. The geometry of the spray jet and the
sprayed quantity of the spray medium can be adjusted with the following measures:
nSelection of air and material nozzle
nChanging the atomisation air pressure on the external regulator
nChanging of spray medium pressure
nAdjustment of the needle stroke on the regulator of the hand-held spray gun
nAdjustment of the flat jet regulator on the hand-held spray gun.

3 Safety and responsibility
3.1 Responsibility of the owner
Owner
The owner is the person, who directly operates the machine for commercial or economical pur-
poses or who allows a third-party to use/apply it and who is responsible for the legal product stew-
ardship for the protection of the user, the personnel or third parties.
Owner responsibilities
The machine is used in an industrial environment. The owner of the machine is therefore subject to
the obligations as stipulated by the Occupational Health and Safety Act.
In addition to the safety information in this manual, the country-specific safety, accident prevention
guidelines and environmental protection regulations, applicable at the site of implementation of the
machine must be adhered to.
Furthermore, the owner is responsible for making sure that the machine is always in perfect tech-
nical condition. Therefore, the following applies:
nThe owner must ensure that the maintenance intervals described in this operating manual are
adhered to.
nThe owner must have all safety equipment checked regularly for functionality and complete-
ness.
3.2 Intended use

mechanical loads.
nAlways observe the applicable country-specific safety, accident prevention, occupational
safety, and environmental protection regulations applicable for the area of use for the hand-
held spray gun.
nThe chemical resistance of the materials which we use cannot always be assessed with
authority due to the large number of fluids, concentrations, temperatures and impurities used.
For this reason, please test the suitability because we cannot offer any guarantees in this
regard.
nWhen processing solvent-containing paints, it is imperative to avoid open flames, red-hot
parts, and equipment, tools, and parts that can create flammable sparks in the work area.
