Safety Warnings

Please pay special attention to the following safety warnings prior to taking this
spray gun into operation!
• Wear proper respiratory protection masks and protective overalls, whenever
you are operating this spray gun. Air-borne particles represent a health
hazard.
• Make sure to wear suitable haering protectors. The gun produces sound
levels of up to 86 dB (A) which may cause hearing defects.
• Open fires, naked lights and smoking prohibited in the working area. Spraying
of readily flammable media such as paints and adhesive compounds is
always accompanied by the risk of fire and explosion.
5.2 Starting / Stopping Requirements
The following requirements must be met before taking this spray gun into operati-
on:
• control air must be available at the gun.
• atomizing air must be available at the gun.
• material pressure must be available at the gun.
Caution
The material pressure shall not exceed
• 10 bar,
as, otherwise, the functional reliability of the spray gun will suffer.
Adjust the control air pressure to
• at least 4,5 bar, in order to operate the spray gun.
The operation of the spray gun can be started/stopped by way of the 3/2-way con-
trol valve (see the Operating Instructions of the plant systems manufacturer).
Warning
It is important to remember that the spray gun must be relieved of all pressures
whenever work is terminated. Lines left in pressurized condition could burst, with
their contents likely to injure anybody present nearby.
