1. If the airbrush only blows air but no paints out, here are two frequent possible reasons:
(1) Nozzle or Needle Clogged.
Solution: Remove and Clean the needle or nozzle.
Note: The nozzle and needle are fragile, so you need to take it down gently and carefully.
(2) Loose Needle Chucking Nut.
Solution: Tighten the chucking nut and press the trigger to ensure that the needle inside can be driven together with the nut.
Note: DO NOT turn the nut too tight, or it might be damaged.
2. When disassemble the airbrush, please MUST keep gentle and smooth!!!! The parts inside are delicate and fragile.
