SPRAY PATTERNS
Dried material is clogging
side-port "A" and causing
side-port "B" to blow spray
towards theclogged side
Dried material at fluid
nozzle "C" restricts air flow
Loose air nozzle
Air pressure set too high
Remove air nozzle.
Wipe off fluid tip using a
cloth soaked in thinner
or by soft brush
Fasten nozzle securely
Reduce air pressure
Fluid nozzle cracked or worn
Leak at thread of fluid nozzle
Leak at fluid needle
Needle packing worn out Insufficient
fluid in cup
Vent hole in container cover clogged
Tighten or replace
Tighten fluid nozzle
Tighten compression nut
assembly or replace
needle packing
Replace packing
Fill cup with fluid
Clean Out
Air pressure too high
Turn pattern control knob
clockwise to decrease fan width.
Turn fluid needle adjusting nut
counter-clockwise to increase
fluid flow
Soak side-ports in
thinner to clean clog.
DO NOT poke any
opening with hard objects.
