  If your Graco Paint Sprayer does not operate, there are several potential causes and solutions: * The valve might be closed or clogged. Clear the air line and increase the air supply. Also, check that the valves are open. * The fluid hose or gun could be obstructed. Clean the hose or gun. * Dried fluid on the displacement rod can prevent operation. Clean the rod and always stop the pump at the bottom of the stroke. Keep the wet-cup filled with a compatible solvent. * Dirty, worn, or damaged air motor parts may be the issue. Clean or repair the air motor.
