• Always wear hearing protection when using the gun or when in the vicinity of a gun that
is in use. The noise level generated by the spray gun is approx. 83 dB (A).
• After carrying out assembly or maintenance work, always ensure that all nuts, bolts and
screw connections have been fully tightened before the gun is used.
• Use only original replacement parts, since WALTHER can only guarantee safe and fault-
free operation for original parts.
• For further information on the safe use of the spray gun and the spraying materials, plea-

Starting / Handling
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 (round jet / flat jet) must be available at the gun
• The material pressure must be available at the gun.
Caution
The material pressure should not exceed
• 8 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 con-
trol 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
injure any persons in the vicinity.
Spray Pattern Test
Spray pattern tests should be performed whenever:
• the spray gun is taken into operation for the first time;
• the spraying medium is changed;
• the spray gun was taken apart for maintenance or repair works.
The spray pattern is best tested using a workpiece sample, a sheet of metal, card-
board or paper.
Spray Pattern Adjustment
Material flow rate
In order to establish the material flow rate choose a suitable nozzle size. Further-
more 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 instruc-
tions and safety warnings issued by the manufacturer.
