Troubleshooting - airless Spraying
Possible cause
Worn or incorrect tip and/or insufficient
atomization.
Hose size or length is too small or too
long.
Dirty filter.
Needle may not be seating correctly.
Increase spring tension.
Particles too large for spray tip are passing
filter and/or gun screen.
Restrictions in the fluid system.

correction
Be sure the tip is not worn. Increase
pressure. Lower viscosity. Reduce
surface tension by increasing hose size to
minimize pressure drop through hose and/
or reduce hose lengths. Use preorifice
disc (H disc).
Needle-orifice combination should be
factory relapped. Needle packing may
be too tight. Loosen as much as possible
without leakage.
Turn adjusting screw on back of gun
clockwise to increase tension or use the
green HP spring Part # 701-098.
Use 100 mesh gun screen instead of 50
mesh for small spray tips. Use 100 mesh
screen in pump filter. Strain paint.
Check gun and pump filter screens.
Always clean screens before they load up.
Check siphon hose assembly to be sure no
air is entering, then recheck all threaded
fittings for leakage. See Troubleshooting
- Fluid Section for additional service
information.
Inspect for siphon hose leak.
Disassemble and clean gun.
Inspect for siphon hose leak.
Check fluid supply.
Remove, clean, inspect foot valve.
Clean filters or tip.
Clean and inspect pump ball check valve.
