times.
►
Use the spray gun only in well-ventilated rooms. Fire, naked flames and smoking
are strictly prohibited within the working area. WARNING – during the spraying
of flammable materials (e.g. lacquers, adhesives, cleaning agents, etc.), there is
an increased risk to health as well as an increased risk of explosion and fire.

rately or in connection with the equipment with which it is being used
(max. resistance 10
6
Ω).
►
Before carrying out maintenance or servicing work, always ensure that the air
and material feed to the spray gun have been de-pressurised. Risk of injury!

When spraying materials, do not place your hands or other parts of the body
infront of the pressurised nozzle or the spray gun. - Risk of injury!
►
Never point the spray gun at persons or animals. - Risk of injury!
►
Always observe the spraying and safety instructions given by the manufacturers
of the spraying material and the cleaning agent. Aggressive and corrosive mate-

►
Exhaust air containing particles (overspray) must be kept away from the working
area and personnel. In spite of these measures, always wear the regulation
breathing masks and protective overalls when using the gun. Airborne particles
