Daily Cleaning
After every use, it's critical to thoroughly clean your spray gun:
- Flush the system - Run solvent through the gun until it comes out clear
- Disassemble key parts - Remove the air cap, fluid tip, and needle

- Remove and inspect all seals and gaskets
- Check for wear on the needle and nozzle
- Lubricate moving parts with appropriate gun oil
- Test spray pattern on a test surface
