1. Suggest to use 5HP air compressor with 25 gallon air tank for your system.

2. Choose a right nozzle size for different viscosity material.

3. Install cup/hose fittings by hands first and then tighten with wrench lightly. (loose cup by wrench all the time, don’t loose it by hands)

4. Use a good air regulator (P/N reg-34H) to instead of air flow control valve (cheater valve), a good air regulator provides a stable air pressure to your guns which is very important to get a good fan and atomization while spraying

5. set up inlet pressure to 40psi (before push trigger) and rise the pressure for thicker material, if necessary

6. You may need to clean your gun with solvent first

7. Open built-in cheater valve

8. Adjust fluid control knob (which is behind the needle) to proper position

9. If you spray with pressure pot, adjust proper pressure to pot, may be 2psi to 10psi for 2 quart pressure pot. 5psi to 30psi or higher to 2 gallon pressure pot. Pressure can vary for different viscosity material.
