TROUBLESHOOTING DEFECTIVE SPRAY PATTERNS
The following procedure summarizes the steps that an
operator must immediately take when the first signs of
a defective spray pattern emerge.
1. Check the external portion of the fluid tip for material
buildup. If buildup has occurred, secure the gun
trigger safety switch and clean the gun fluid tip with
a non-metal soft brush.
2. If the spray pattern exhibits signs of tails at the top or
bottom ends of the pattern, increase the air pressure
gradually until the tails disappear.
3. If increasing air pressure does not dissipate the tails,
the fluid tip may be worn and may need to be
replaced. Another sign of the need to replace a worn
tip is a gradual decline in spraying pattern width.

The MAG II Automatic manifold mounted air-assisted automatic HVLP spray gun combines the proven efficiency of the
Binks compliant spray guns with air-assisted atomization to yield a reliable, carefully engineered compliant spray gun.
With 25' of 5/16" I.D. air hose and regulator set at only 15 p.s.i. the compliant air cap registers 10 p.s.i. of atomization
air to shape and soften the spray pattern. The MAG II Automatic manifold mounted air-assisted automatic HVLP spray gun
operates at high transfer efficiencies and fully complies with all government regulations for HVLP spray guns.
