What to do if my DeVilbiss COBRA 3C Paint Sprayer has a dry spray?
- T
  Tyler LawsonAug 17, 2025
  If your DeVilbiss Paint Sprayer's spray pattern is dry, it could be due to several reasons: the air pressure might be too high, the gun may be too far from the work surface, the gun motion might be too fast, or the fluid flow could be too low. To fix this, reduce the air pressure, adjust to the correct distance, slow down your motion, and increase the fluid flow or use a larger nozzle size.

What to do if my DeVilbiss COBRA 3C Paint Sprayer has a jerky or fluttering spray?

  Sarah GrossAug 20, 2025
  A jerky or fluttering spray from your DeVilbiss Paint Sprayer can occur if the material level is too low or if there's an obstruction in the fluid passage. Refill the material and back flush with solvent to clear any obstructions.

Why is fluid leaking between the spray gun and the manifold on my DeVilbiss Paint Sprayer?
- B
  brockalisonAug 23, 2025
  If fluid is leaking between the spray gun and the manifold of your DeVilbiss Paint Sprayer, it's likely due to damaged or missing O-rings or a Torx screw that is not tight. Replace the O-rings using kit SPA-412-K and tighten the Torx screw or replace it using kit SPA-411-K.

Why is my DeVilbiss COBRA 3C Paint Sprayer gun loose on the manifold?

  batesmarioAug 26, 2025
  If the spray gun is loose when assembled onto the manifold of your DeVilbiss Paint Sprayer, it is likely that the Torx screw is not tight. Tighten the Torx screw to 1.8-2.0 Nm (1.3-1.5 lbf.ft) or replace it using kit SPA-411-K.

How to prevent runs and sags with my DeVilbiss Paint Sprayer?
- K
  Keith SheltonAug 28, 2025
  If your DeVilbiss Paint Sprayer is producing runs and sags, it's likely due to too much material flow, material that is too thin, or motion that is too slow. Reduce the fluid flow or switch to a smaller fluid nozzle and fluid needle size. Ensure your materials are mixed correctly or apply light coats, and increase the gun traverse speed.

Why is fluid leaking from the front of my DeVilbiss COBRA 3C Paint Sprayer?
- M
  Miguel CarpenterAug 31, 2025
  If you notice fluid leaking or dripping from the front of your DeVilbiss Paint Sprayer, it could be caused by a worn or damaged fluid nozzle or fluid needle, foreign matter in the fluid nozzle, a dirty fluid needle or one stuck in the needle packing, or using the wrong size fluid needle or fluid nozzle. Replace the fluid nozzle and fluid needle, or clean the affected parts.

Why does my DeVilbiss Paint Sprayer have a split spray pattern?
- J
  Jamie NelsonSep 3, 2025
  A split spray pattern from your DeVilbiss Paint Sprayer can occur if the fluid flow is set too low or the fan air pressure is set too high. Increase the fluid flow and decrease the fan air pressure to achieve the correct pattern.

- J
  John BellSep 5, 2025
  If your DeVilbiss Paint Sprayer has a fluid-starved spray pattern, it indicates inadequate material flow. Increase the fluid flow, change to a larger fluid nozzle size, and check the hose for any blockages.

Why does my DeVilbiss COBRA 3C have a heavy center pattern?
- K
  Kathy JohnstonSep 8, 2025
  If your DeVilbiss Paint Sprayer is producing a heavy center pattern, it may be due to the fan air pressure being set too low or the material being too thick. Increase the fan air pressure to achieve the correct pattern and thin the material to the correct consistency.

How to fix a heavy spray pattern on my DeVilbiss COBRA 3C Paint Sprayer?
- M
  Michael PerezSep 12, 2025
  A heavy top, bottom, right, or left side pattern from your DeVilbiss Paint Sprayer can be caused by plugged horn holes, an obstruction on the fluid nozzle, or dirt on the cap or nozzle seat. Clean these parts with a non-metallic point.
