it for future reference!
On the last page of this instruction book, there is a form for documenting safety inspections, which
have to be conducted at regular intervals. The form has only to be filled out by qualified Person
(persons with sufficient knowledge and experience or manufacture´s mechanics) or experts (e.g.
engineers or Technical Control Board experts).
Safety inspections must be conducted before commissioning and at least once a
year!

described below. A usage not according to the intended purpose as well as unauthorized
modifications exclude the liability of the manufacturer for any damages resulting from this.
The devices and machines are only to be used according to the intended purpose
explicitly described below!
These machines are to be used for cleaning varnish and spray paint guns as well as paint soiled parts
and hand tools using solvents (A I, A II, A III) or non-combustible, aqueous cleaners for water-based
paints. The Acetone content of the solvent used must be less than 65 %.
These gun cleaners must not be subjected continuous operation, such as, for instance, the serial
production. Improper use of the washers can endanger the health of the operator and of others and
cause damage to the cleaner itself or to other materials and assets.
Improper use of the cleaners can endanger the health of the operator!

3. Safety requirements
3.1 General security
The device is built according to the state of the art and is safe to operate. However, this does not
mean that the consequences of all operational failures are protected by technical measures. Dangers
can arise from this cleaning device if it is used unqualified or improperly. However, additional
organizational measures have to be taken into account through certain workflows, such as the
removal of residual paint from the gun.
• Read and observe the operating instructions for the cleaning unit as well as the safety
instructions before commissioning.
• Keep the operating instructions in the vicinity of the device accessible.
• The unit may only be operated by trained personnel. Young people under the age of 18 may
be employed only under the supervision of a specialist.
For some users hazard assessment activity restrictions may result, e.g. for persons with
chronic respiratory problems or allergic diseases as well as for becoming or nursing
mothers.
For the operation of the cleaning device, the safety and operating instructions are valid in
all cases; these must be noticed and observed!
The following occupational safety provisions, rules and information (DGUV) have to be followed
while using spray gun and part cleaning systems:
DGUV Provision 1 "Principles and prevention", general rules
DGUV Provision 9 "Safety and health protection warnings at the workplace"
DGUV Rule 109-002 "Safety rules for air pollution control systems for the workplace"

3.2 Security checks
In order to meet the requirements of the DGUV regulation 109-010, there is the necessity to check
the cleaning device for "safe working condition" before initial start-up as well as annually.
In the appendix of this operating manual, the "Safety test sheet" form is available for proof of regular
safety tests. The form in connection with the tests to be carried out may only be carried out by
qualified persons. Qualified persons are specialists who, due to their training and experience, are
technically able to assess the working condition of a work equipment. For a specific definition of a
qualified person, please refer to the definition of the operational safety ordinance BetrSichV.
3.3 Operational safety
Follow warnings and warning signs!
• Fire, open light and smoking prohibited!
• Open fires and other sources of ignition (eg grinders or welding points) are not allowed within a
radius of 5 meters around the device. This applies e.g. also for lighting and fans as well as the
associated electrical components.
• In all cases, the local safety and operating instructions are valid for the operation of the device.
Accident prevention regulations must be followed and observed.
The device may only be operated if the integrated suction device (Venturi system with
flexible exhaust hose) is connected and the evolved (solvent) fumes are safely discharged
to the outside in the free air stream in order to avoid fire, explosion and health hazards.
Should the distance to be bridged exceed the length of the supplied exhaust air hose or should local
requirements exclude the previously described exhaust air guidance, we recommend the inclusion of
a specialist company for ventilation construction to ensure the correct operation of the device.
• Compliance with workplace exposure limits (AGW) according to safety data sheets must be
documented.
• The limit values of the TA-air and their adherence must be observed.
• In the event of a fire, immediately interrupt the compressed air supply and close the cover of the
device.
