  If paint leaks out of the cup threads of your Graco Paint Sprayer, consider these points: * Ensure there is only one FlexLiner in the Cup Support. * Make sure the cup cover is properly threaded to the Cup Support. If threads are visible when tight, remove and reinstall it so no threads are visible. * Ensure the cup cover is tightened so the arrow is within range of the indicator. * Avoid flexing or pushing on the Cup Support when you evacuate air from the FlexLiner. * Avoid pulling down on the FlexLiner when you evacuate air. * Check for damage to the FlexLiner lip or cup cover gasket. * Ensure the FlexLiner lip and cup cover gasket are free of debris and dried paint. * Replace the FlexLiner.
