Page 8: Operation
Operation Operation Pressure Relief Procedure 1. Turn off the gun air supply. 2. Trigger the gun to relieve pressure. Apply Fluid CAUTION Excessive atomizing air pressure can increase over-spray, reduce transfer efficiency, and result in a poor quality finish. Regulatory agencies in certain states prohibit the operation of a spray gun above 10 psi (69 kPa, 0.7 bar) atomizing air cap pressure. -
Page 9: Daily Gun Maintenance
Daily Gun Maintenance General Tasks Follow the Pressure Relief Procedure, page 8. • Frequently lubricate the gun moving parts with a drop of non-silicone oil. • Do not disassemble the spray gun if you are having a spray pattern problem.
