Why is my DeVilbiss Paint Sprayer producing excessive overspray (spray mist)?
- K
  Kimberly NielsenAug 20, 2025
  Excessive overspray from your DeVilbiss Paint Sprayer can occur due to several reasons: the atomization air pressure might be too high, the gun may be too far from the work surface, or the stroking motion might be improper (arching, gun motion too fast). To resolve this, reduce the pressure, adjust to the proper distance from the surface, and move at a moderate pace parallel to the work surface.

How to fix jerky or fluttering spray from my DeVilbiss EGA-503?
- B
  Brittany LewisAug 22, 2025
  A jerky or fluttering spray from your DeVilbiss Paint Sprayer could be due to several factors: a loose or damaged fluid tip/seat, low material level, the container being tipped too far, an obstruction in the fluid passage, a loose or broken fluid tube or fluid inlet nipple, or a dry or loose needle packing nut. To fix this, try the following: * Tighten or replace the fluid tip/seat. * Refill the material. * Hold the container more upright. * Clean any obstructions in the fluid passage. * Tighten or replace the fluid tube or fluid inlet nipple. * Lubricate or tighten the needle packing nut.

What to do if my DeVilbiss EGA-503 Paint Sprayer has a heavy center pattern?
- R
  Rachel WilliamsAug 25, 2025
  A heavy center pattern on your DeVilbiss Paint Sprayer may be due to material flow exceeding the air cap’s capacity, atomizing pressure being too low, or the material being too thick. Try thinning the material or lowering the fluid flow, increasing the pressure, or thinning the material to the proper consistency.

  If your DeVilbiss Paint Sprayer will not spray, check the air supply and air lines to ensure there is air pressure at the gun. Also, make sure the needle adjusting screw is open enough.

How to fix a split spray pattern with my DeVilbiss EGA-503 Paint Sprayer?
- D
  debra61Aug 28, 2025
  A split spray pattern with your DeVilbiss Paint Sprayer can occur if the fluid adjusting knob is turned in too far, there is insufficient material flow, the atomization air pressure is too high, or there is too much fan air. To correct this, back out the fluid adjusting knob counterclockwise to achieve proper flow, increase fluid pressure (if using pressure feed), reduce air pressure, and turn the fan adjust in to reduce fan air.

How do I fix a heavy right or left side pattern with my DeVilbiss EGA-503 Paint Sprayer?
- A
  Ashley PattersonAug 30, 2025
  A heavy right or left side pattern from your DeVilbiss Paint Sprayer could be due to plugged left or right side horn holes, or dirt on the left or right side of the fluid tip. Clean the affected areas, reaming with a non-metallic point if necessary. To further troubleshoot, determine if the obstruction is on the cap or fluid tip by making a test pattern, then rotate the cap one-half turn and spray another pattern. If the defect is inverted, the obstruction is on the air cap; clean it. If the defect is not inverted, it is on the fluid tip; check for a fine burr on the edge of the fluid tip and remove it with #600 wet or dry sandpaper. Also, check for dried material just inside the opening and remove it by cleaning.

  A heavy top or bottom pattern from your DeVilbiss Paint Sprayer may be caused by plugged horn holes, an obstruction on the top or bottom of the fluid tip, or a dirty cap and/or tip seat. To resolve this, clean the affected parts, reaming with a non-metallic point if necessary.

Why is my DeVilbiss Paint Sprayer producing a dry spray?
- H
  hdominguezSep 3, 2025
  A dry spray from your DeVilbiss Paint Sprayer may occur if the air pressure is too high, the gun tip is too far from the work surface, the gun motion is too fast, or the gun is out of adjustment. Try decreasing the air pressure, adjusting to the proper distance, slowing down your motion, and adjusting the gun.

What causes runs and sags when using my DeVilbiss EGA-503?
- N
  Nathan BrownSep 5, 2025
  Runs and sags with your DeVilbiss Paint Sprayer can be caused by too much material flow, material that is too thin, or the gun being tilted at an angle. Adjust the gun or reduce fluid pressure, mix the material properly or apply light coats, and hold the gun at a right angle to the work, adapting proper gun technique.

Why is my DeVilbiss EGA-503 leaking fluid from the packing nut?
- V
  Victoria BrownSep 7, 2025
  Fluid leaking from the packing nut of your DeVilbiss Paint Sprayer is likely because the packing nut is loose or the packing is worn or dry. Try tightening the nut, being careful not to bind the needle. If that doesn't work, replace or lubricate the packing.
