  tanyafergusonAug 15, 2025
  Corrosion on the air cap thread, inside material passages (cup connection), or on the spray gun body can occur if water-based cleaning solution remains inside or on the spray gun for too long, so clean it (see chapter 8) or if you used unsuitable cleaning solutions. You may need to get a replacement spray gun body.

  If your spray gun leaks from the fluid tip, it could be due to contamination between the paint needle tip and fluid tip. Clean the fluid tip and paint needle (see chapter 8). Alternatively, the nozzle set may be damaged, requiring replacement (see chapter 9).

  A spray pattern that is too small, crooked, lop-sided, or splitting may be due to clogged air cap drillings. Clean the air cap (see chapter 8). It could also be due to a damaged fluid tip; check if the fluid tip is damaged and replace the nozzle set if necessary (see chapter 9.1).

What to do if round/ flat spray control of SATA minijet 4400 B Paint Sprayer does not function?
- J
  Jennifer Gonzalez DDSSep 12, 2025
  If the round/flat spray control has no function, but the control knob can still be turned, the air distribution ring may not have been positioned in the correct location (pin is not located in the drilling) or it may be damaged. Replace the air distribution ring, making sure it has been positioned correctly when inserting it (see chapter 9.2).
