Problem Possible cause Solution
Spray gun will not spray
No air pressure Check air supply
Material viscosity far too high Regulate material viscosity
Spray gun wrongly adjusted Follow adjustment procedure to readjust spray gun
Intermittent/sputtering spray
Fluid level too low Rell Paint Container (1)
Dry or worn needle packing seat; air seeping into
uid passage
Tighten packing; lubricate
Leaking Paint Container Lid
or Fluid Connector (3)
Tighten Fluid Connector and Paint Container Lid; inspect Lid seal
Obstruction in uid passage Flush with solvent to dissolve blockage
Packing uid needle too loose causing leaking Tighten or replace packing
Arc-shaped spray pattern
Horn holes clogged
Remove obstructions from horn holes; soak in suitable solvent and wipe clean
Uneven volume of uid from horn holes cause
uid deviation
Spray pattern is not evenly spread
Material builds up on the outside of the uid tip or
centre hole or partially clogs the nozzle orice
Remove obstruction
Loose uid nozzle Tighten uid nozzle
Centre of spray pattern too narrow
Atomising air pressure too high Reduce air pressure
Material too thin Regulate material viscosity
Pattern width too small
Atomising air pressure too low Increase air pressure
Material too thick Regulate material viscosity
No or very little paint output
Fluid passage clogged
Remove obstructions
Air holes in the nozzle blocked
Fluid needle stroke too small
(Material ow too low)
Increase material ow
Excessive overspray
Atomising air pressure too high Reduce air pressure
Spray gun too far from work surface Use proper distance to workpiece
Wrong spray gun movement (arcing, too fast) Move at moderate pace, parallel to the workpiece
Dry spray
Atomising air pressure too high Reduce air pressure
Material not properly prepared Adjust viscosity and re-lter material
Spray gun too far from work surface Use proper distance to workpiece
Spray gun motion too fast Move at moderate pace
Spray gun wrongly adjusted Follow adjustment procedure to readjust spray gun
Runs and sags
Material ow too high Reduce material ow
Material too thin Regulate material viscosity
Gun tilted on an angle Hold gun at right angle to the workpiece; improve spraying technique
