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.

Qualified personnel
Due to their specialised professional training, knowledge, and experience as well as knowledge of
the industry-specific standards and regulations, qualified personnel are in a position to perform
assigned tasks and to identify and avert potential risks on their own.
2.3 Personal protective equipment
Personal protective equipment is used to protect persons from impacts on their occupational health
and safety.
The personnel must wear personal protective equipment while carrying out the various tasks and
while working with the device. The individual sections of this manual will indicate the personal
safety equipment separately.
The selection of the protective equipment depends on the coating material that is used. To
ensure the proper selection of personal protective equipment, the information provided by the
spray material manufacturer indicated on the safety data sheet must be adhered to.
2.4 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.
2.5 Intended use
The pneumatic agitator is used in closed non-pressure or pressurized containers to stir coating
materials with a tendency for sedimentation.
It is mainly used for painting and coating operations.
Proper use also includes adherence to all the specifications in these instructions.
Any use beyond the intended use or any other use constitutes misuse.
