Starting operation Solid Green When the pressure indicator is solid green, the sprayer is operating between 12 MPa (120 bar) and 23 MPa (230 bar). A solid green pressure indicator means: • The sprayer is at the proper pressure setting for spraying oil- based and latex house paints • The sprayer is operating at peak performance at a high pressure setting • If the pressure indicator goes to solid yellow when the pressure is set so that it starts at solid green, it indicates one of the following:...
