To check the function of the Main Air Regulator and Gauge:

1. Locate the main air regulator at the rear of the coating system (Figure 4-8).

2. Rotate the main air regulator counterclockwise until the Main Air Gauge registers zero (0).

3. Rotate it clockwise until the main air gauge registers 586-620 kPa (85-90 psi).

 If the main air gauge fails to register pressure, verify that the coating system is

connected to the facility air source.

 If there is an air leak, identify the source, shut off the facility air, and fix the leak before

proceeding.

 NOTE The regulator assembly is equipped with a relief valve to protect the system

components. Increasing the pressure above 655 kPa (95 psi) may trigger the relief

valve. If so, reduce the air pressure below 655 kPa.

TIP For accurate pressure adjustment, lower the pressure below the desired level and then

increase to the desired pressure.
