2 Safety
2.1 Qualification of Specialists
The spray gun may only be commissioned, operated, serviced and
repaired by qualified and trained personnel.
If you need any support in the training of your
personnel, contact our training department (see
chapter "Contacts & Hotline)".
2.2 Safety of the Work Environment
Ensure that the work environment is always kept clean and well
illuminated.
Ensure that the floor of the work environment is antistatic according to
EN50053 part 1, §7-2, measurement acc. to DIN 51953 and that all
persons are wearing antistatic shoes within the work environment.
Ensure that the operators are wearing antistatic gloves when painting.
This allows a grounding through the spray gun handle.
Follow all local rules concerning the paint mist suction and ensure that
these are available at the workplace and are operated properly.
Ensure that material and air hoses are available and are used that are
laid out for the corresponding working pressure.
Ensure that personal protection outfit is available
to the personnel and this is used. Wearing
personal protection outfit such as breath and skin
protection and anti-slip safety shoes where
appropriate reduces the risk of injuries.
Ensure that there are no sources of ignition such as open fire, sparks,
glowing wires or hot surfaces in the environment and that people do
not smoke in the room.
2.3 Safe Handling of the Spray Guns
Check the firm seat of all screws and nuts before every
commissioning, in particular after maintenance and cleaning works.
Attention: The spray jet is pressurized and may cause dangerous
injuries.

Please pay attention to the following safety note at all times:
- Absolutely avoid direct skin contact with paint or cleaning agents.
- Always wear safety clothing such as goggles, breath mask,
protection suit, safety shoes and gloves.
- Never direct the spray gun towards yourself, other persons or
animals and never reach into the spray jet.
- Disconnect the compressed air supply before all jobs at the device
and in case of stoppages and malfunctions.
- In case of stoppages, ensure that the spray gun is not triggered by
mistake.
- Before maintenance operations, relieve the spray gun pressure.
- In case of malfunctions, eliminate the error according to chapter
6.8 "Possible errors".
Danger of skin injuries:
In case of skin injuries by paint or cleaning agent, note down which
paint and/or cleaning agent you have used and you consult a doctor
immediately.
2.4 Grounding
Due to the high flow velocity of the paint and the air, electrostatic
charges may occur at the device. These may cause spark or flame
formation in case of discharge.
- Ensure that the device is grounded during every spraying process
and ground the workpieces to be coated.
- All persons inside the working area should be grounded, for
instance by wearing antistatic shoes. In addition, antistatic gloves
should be worn during painting for grounding through the spray
gun handle.
2.5 Material and Air Hoses
Ensure that the connected material and air hoses meet the
mechanical and chemical requirements. Pay attention to the data
sheets of the paint manufacturers. Make sure that the material of the
material hose is chemically steady against the sprayed materials.
Make sure that on the used high-pressure hose the manufacturer, the
manufacturing date and permissible operating pressure are
recognizable.
Attention: The electrical resistance of the complete highpressure hose must be smaller than 1 MOhm.

2.6 Cleaning
- Uncouple the device from the pneumatic inlet and relieve the
pressure.
- Ensure that the ambient temperature is at least 5°C below the flash
point of the used cleaning agents.
- Only use moistened cloths and paintbrushes to clean. Never use
any hard objects and never spray on cleaning agents with a gun.
Attention: In closed tanks, an explosive gas-air-mixture may
form. Therefore, never spray into a closed tank when cleaning
the device with solvent.
2.7 Handling of Liquids, Paints and Enamels
When preparing and processing paints and when cleaning the device,
observe all processing rules by the manufacturers of the used paints,
solvents and cleaning agents.
When painting and preparing and cleaning, wear the stipulated
protection outfit:
- goggles
- protective clothes
- protective gloves
- skin protection cream where appropriate
- respirator
Operate the device in a spray booth or at a spray wall with ventilation
turned on (suction) to ensure sufficient health and environmental
protection.
Wear corresponding protective clothing when processing hot materials
(max. 60°C).
