What to do if Graco Magnum True Airless X5 runs, but doesn't prime?

If your Graco Paint Sprayer pump is running but not priming, make sure the Prime/Spray valve is in the PRIME position until paint comes out of the drain tube. Also, check that the inlet strainer isn't clogged and the suction tube is fully immersed in the paint. If the paint is thick, try momentarily turning the ON/OFF switch off and on.
