Warning
Material and air hoses which are installed with a hose grommet must be additionally
secured with a hose clamp.
5 Operational Handling
5.1 Safty 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 83 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 the spray gun is operated:
• The control air pressure must be available at the gun.
• The atomizing air pressure must be available at the gun.
• The material pressure must be available at the gun.
• The scavenger pressure must be avaiable at the gun.
Caution
The material pressure should not exceed • 6 bar , since otherwise the operational
reliability of the spray gun will be impaired. The control air pressure should be set at
• minimum of 4,5 bar , in order to operate the gun.
The operation of the spray gun can be started/stopped by way of the 3/2-way control
valve (see the operating instructions of the plant systems manufacturer).
Warning
It is important to remember to relieve the spray gun of all pressures when work is
terminated. Lines left under pressure may burst and the released material may inju-
re any persons in the vicinity.
5.3 Spray Pattern Adjustment
Material flow rate
In order to establish the material flow rate choose a suitable nozzle size. Furthermore
it is dependent on the upcoming material pressure.
Regulate the material pressure
Adjust the material pressure at the pump or the material pressure tank - make sure
to follow relevant instructions and safety warnings of the manufacturer!
Regulate the atomizing air pressure
The atomizing air pressure is continuously variable adjusted at the arranged air
pressure-reducer in the plant system. Please comply with the operating instructions
and safety warnings issued by the manufacturer.
Regulate the control air pressure
The control air pressure is to be adjusted at the air pressure reducing valve of the
compressor system. Please comply with the operating instructions and safety war-
nings issued by the manufacturer.
6 Cleaning and Maintenance
• Make sure that the spray gun is in unpressurised condition, i.e. all air and mate-
rial inputs must be shut off - if not, imminent Risk of Injury.
• Open fires, naked lights and smoking is prohibited in the working area. There is
an increasing risk of fire and explosion, when spraying readily flammable media
(such as cleaning solutions).
• Observe all processing specifactions and safety warnings issued by the manuf-
acturer of cleaning media. Especially aggressive and corrosive media repre-
sents risks and hazard to personal health.
6.1 Cleaning - Complete
Regular cleaning and lubrication of the spray gun has to be performed, in order to
increase the service life and the function of the spray gun.
Clean the gun only with cleaning solutions recommended by the manufacturer of the
spraying material, which do not contain any of the following constituents:
• halogenated hydrocarbons (e.g. 1,1,1, trichloroethane; methylene chloride, etc.)
• acids and acidiferous cleaning solutions
• regenerated solvents (so-called cleaning dilutions)
• paint removers
