How to fix fluid tip leakage in Central Pneumatic 93305 Paint Sprayer?

  If you're experiencing fluid tip leakage with your Central Pneumatic Paint Sprayer, there are several potential causes. The tip might be dirty, so try cleaning it. The packing nut could be too tight, so loosen it slightly. A broken fluid needle spring could also be the culprit, requiring a replacement. Lastly, the tip could be worn or damaged, in which case you should replace the tip and/or needle.

Why is my Central Pneumatic Paint Sprayer sputtering?
- R
  Raymond ThompsonAug 13, 2025
  Sputtering spray from your Central Pneumatic Paint Sprayer can occur for several reasons. It may be due to a low material level (refill the cup), the cup being tipped too far (hold it upright), a clogged air vent (clean the vent hole), loose fluid inlet connections (tighten them), a dry or loose fluid needle packing nut (lubricate and/or tighten), or a loose/damaged fluid tip/seat (adjust or replace it).

  If your Central Pneumatic Paint Sprayer won't spray, several factors could be at play. First, check the air hoses to ensure there's pressure at the gun. Also, make sure the fluid control is open enough. Finally, the fluid might be too thick; try thinning it or increasing the pressure, staying within the maximum range.

Why Central Pneumatic Paint Sprayer has overspray?
- P
  Pamela MorenoAug 25, 2025
  Overspray with your Central Pneumatic Paint Sprayer can be attributed to a few reasons. You might be applying the paint too quickly, so move moderately and parallel to the surface. The distance from the workpiece could be incorrect, so adjust it accordingly. Also, excessive air pressure can cause overspray, so reduce the air pressure.

  If fluid is leaking from the packing nut of your Central Pneumatic Paint Sprayer, it could be due to a loose packing nut. Try tightening it without restricting movement. Alternatively, the packing may be worn or dry, in which case you should replace or lubricate it with a non-silicone lubricant.
