2.2.1 Safe handling of Optima paint spray guns
a) Examine before each start-up, in particular after maintenance and cleaning works the firm seat
of all screws and nuts/mothers.
b) Attention: The spray jet is under pressure and can cause serious injuries.
c) The following safety instructions should be followed at all times the spray gun is used:
- Avoid in any case injection of colour or cleaning agents.
- Never aim the spray gun to yourself, other persons or animals and never put your
hand or any other body parts into the spray jet.
- Separate the energy and compressed air supply at all times before working on the
equipment, as well as work interruptions and malfunctions.
- In case of work interruptions secure the spray gun against operation.
- Relieve spray gun and equipment from pressure.
- In case of malfunctions, please repair the error according to chapter. „ Trouble
shooting " page 10.
d) Danger of skin injuries:
Note in case of skin injuries by colour or cleaning agent, which colour and/or cleaning agent you
used and consult immediately a physician.
f) Danger by recoil forces:
- In order to counter recoil forces, make sure that during operation you stand safely and change
your position regularly to avoid fatigue.
2.2.2 Grounding
Due to the high flow rate of the colour and air electrostatic loading of the equipment is possible.
When unloading these can cause sparks or flames.
- Make sure the equipment is grounded while operating and also ground the work pieces to be
coated.
- All persons within the work area should be grounded, e.g. by wearing antistatic shoes and when
operating the spray gun antistatic gloves should be word for grounding over the handle of the spray
gun.
2.2.3 Material- and air hoses
- Ensure that only material and air hoses are used which are laid out for the appropriate operating
pressures.
- 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 high-pressure hose must be smaller than 1 MOhm.
2.2.4 Cleaning
- Decouple the equipment from the pneumatic inlet and relieve the pressure.
- Make sure that the ambient temperature is at least 5°C under the flash point of the used cleaning
agents.
- Use for cleaning only solvent-damp rags and brushes. Use in any case hard articles and never
spray apply cleaning agents with a spray gun.
Attention: In closed containers a combustible gas air mixture can form. Therefore never spray
during equipment cleaning with solvents into a closed container.
