Why is there excessive overspray from my DeVilbiss Paint Sprayer?
Excessive overspray from your DeVilbiss Paint Sprayer can occur if the air pressure is too high or the gun is too far from the work surface. Try reducing the air pressure and adjusting the distance to the correct range.
Why is my DeVilbiss Paint Sprayer producing a dry spray?
Dry spray from your DeVilbiss Paint Sprayer can occur if the air pressure is too high, the gun is too far from the work surface, the gun motion is too fast, or the fluid flow is too low. Reduce the air pressure, adjust to the correct distance, slow down your motion, or increase fluid flow by adjusting the needle or using a larger nozzle.
What to do if my DeVilbiss Paint Sprayer has a starved spray pattern?
A starved spray pattern in your DeVilbiss Paint Sprayer may be due to inadequate material flow, a blocked vent in the cup lid, or low atomization air pressure. Try winding the fluid adjusting knob out, changing to a larger fluid nozzle size, cleaning the lid and unblocking the vent, and increasing the air pressure while rebalancing the gun.
Why does my DeVilbiss ADVANCE HD Paint Sprayer have a heavy center pattern?
A heavy center pattern from your DeVilbiss Paint Sprayer may be due to the spreader adjustment valve being set too low, atomizing pressure being too low, or the material being too thick. Turn the spreader adjustment valve out counterclockwise to achieve the correct pattern, increase the pressure, or thin the material to the correct consistency.
How to fix a split spray pattern on my DeVilbiss ADVANCE HD?
A split spray pattern with your DeVilbiss Paint Sprayer can be caused by air pressure that is too high, the fluid adjusting knob turned in too far, or the spreader adjusting valve set too high.

How to prevent runs and sags with my DeVilbiss ADVANCE HD?
Runs and sags when using your DeVilbiss Paint Sprayer can be caused by too much material flow, material that is too thin, or incorrect gun handling.

Material level too low. 4. Container tipped too far. 5. Obstruction in fluid passage. 6. Loose fluid needle packing nut. 7. Damaged fluid needle packing. To resolve this, tighten or replace the fluid nozzle/seat or cup fluid nipple, refill the cup, hold the container more upright, back flush with solvent, or tighten/replace the fluid needle packing nut.
Why does my DeVilbiss Paint Sprayer have a heavy spray pattern on one side?
A heavy top, bottom, right, or left side pattern from your DeVilbiss Paint Sprayer may be due to plugged horn holes, obstructions on the fluid nozzle, or dirt on the cap or nozzle seat. Clean the affected areas, reaming with a non-metallic point where necessary.
