  • Page 16 Setup Adjust Spray Pattern Do not exceed 100 psi (0.7 MPa, 7 bar) maximum fluid and air pressure. Higher pressures can cause parts to rupture and result in serious injury. Use the fluid pressure regulator to adjust the spray gun fluid flow. Some models are equipped with a fluid control knob to make pre- cise fluid flow adjustments.
