Troubleshooting
Problem
Possible Cause
Solution
Spray gun will not spray
No air pressure
Check air supply
Material viscosity far too high
Regulate material viscosity
Filter clogged
Remove filter element inside paint container connection and clean with
solvent
Spray gun wrongly adjusted
Follow adjustment procedure to readjust spray gun
Intermittent/sputtering spray
Fluid level too low
Refill paint container
Dry or worn needle packing seat; air seeping
into fluid passage
Tighten packing; lubricate
Leaking paint container connection
Check O-ring of paint container connection; tighten paint container
Obstruction in fluid passage
Remove filter element inside paint container connection and clean with
solvent ; flush spray gun with solvent to dissolve blockage
Packing fluid 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 fluid from horn holes cause
fluid deviation
Spray pattern is
not evenly spread
Material builds up on the outside of the fluid tip
or centre hole or partially clogs the nozzle orifice
Remove obstruction
Loose fluid nozzle
Tighten fluid 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 flow
too low)
Increase material flow
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-filter 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 flow too high
Reduce material flow
Material too thin
Regulate material viscosity
Gun tilted on an angle
Hold gun at right angle to the workpiece; improve spraying technique
If the above troubleshooting solutions fail, contact your dealer or an authorised Silverline service centre.
