Proper maintenance of your spray gun is crucial for achieving professional results and extending the life of your equipment. In this comprehensive guide, we'll walk you through the essential steps.
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

Weekly Deep Clean
Once a week, perform a more thorough cleaning:
- 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
Troubleshooting Common Issues
