Troubleshooting
Symptom
Intermittent spray
• Presence of air in the
paint circuit
• Material residue in the
holes obstructs the pas-
sage of material
• The nozzle is dirty or
malfunctioning
• The atomization cap is
dirty or damaged
• Submerge the head in solvent
• Clean and open all closed
holes with a jet of compressed
air or a toothpick.

objects, or you may deform
the hole of the head part.
• Material builds up on the
outside of fluid nozzle tip
or center hole or partially
clogged nozzle orifice.
• Loose fluid nozzle
• Clean the head and the nozzle
• Make sure that the centering
between the two is precise
• Check that the tip of the pin is
not ruined
• Replace the nozzle and the
head
• Atomization of air
pressure is too high
• Material too thin
• Reduce the quantity of air and
increase the flow of paint.
• The flow of paint is
greater than the pressure
and quantity of air
supplied.
• Fluid passage is clogged
with dirt
• Air holes in the cover are
blocked
• Fluid needle stroke is too
short
• Clean the head and the nozzle

too dense and dilute if
necessary

• Make sure that the tank is not
empty.
• Check that the connecting hole
is not obstructed.
• Tighten the gland screw or
replace the gasket if worn
