Common Problems
Problem Possible Cause Corrective Action
1. Spray gun spitting Dirty or worn ball tip or fluid tip Clean or replace the ball tip and fluid
tip.
Air bubbles in fluid stream Bleed air from the fluid delivery
system. Check for leaks in the fluid
delivery system or excessive
agitation in the fluid reservoir.
Fluid pressure too low Increase the fluid pressure.
2. Fluid leaking around
the nozzle or retaining
ring
Worn or damaged nozzle gasket
or gasket with restrictor
Replace the nozzle gasket or gasket
with restrictor.
Worn or damaged air piston or
other air seals
Replace the piston O-rings or other
seals.
3. Fluid leaking from
rear of extension
Worn or damaged packing

4. Low or erratic fluid
flow
Fluid delivery system malfunction Check the fluid delivery system (air
and fluid).
Blockage within spray gun, fluid
hose, or fluid system
Flush the system. If necessary,
repair or replace clogged or damaged
components.
Low fluid pressure WARNING: Do not exceed the
maximum fluid pressure rating of 103
bar (1500 psi). Failure to observe
this warning may result in death or
personal injury.
Slowly increase the fluid pressure
until the desired fluid flow is obtained.
Fluid too viscous Lower the viscosity by adding solvent
or increasing the fluid temperature.
5. Coarse spray Fluid too viscous Lower the viscosity by adding solvent
or increasing fluid temperature.
Solvent evaporates too quickly Use slower evaporating solvent.
Contact your material supplier.
Clogged or damaged nozzle,
restrictor, or fluid tip
Clean and inspect the nozzle,
restrictor, and fluid tip. Replace them
if they are damaged.
Gun control unit is off Turn on the gun control unit.
6. Excessive bounce
back
Fluid pressures too high Reduce the fluid pressures.
7. Dry spray Spray gun held too far away from
substrate
Move the spray gun closer to the
substrate.
