      If your Graco Paint Sprayer has stopped spraying, consider these potential causes: * The pump might not have been primed with flushing fluid. Remove the suction tube from the paint and prime the pump with water or flushing solvent-based flushing fluid. * The suction tube could be leaking. Tighten the suction tube connection and inspect it for cracks or vacuum leaks. * The spray tip might be clogged. Unclog the spray tip.

    What to do if my Graco Magnum ProX7 Paint Sprayer power switch is on but the motor doesn't run?
    • B
      Bryan LopezAug 28, 2025
      If your Graco Paint Sprayer's power switch is on and the sprayer is plugged in, but the motor doesn't run, first ensure that the pressure isn't set to zero; turn the pressure control knob clockwise to increase the pressure setting. Then, check if the electric outlet is providing power by verifying that the lighted plug on the sprayer is lit; if not, reset the building circuit breaker or replace the fuse. A damaged extension cord or sprayer electric cord could also be the culprit, so inspect and replace them if necessary.

    Why does paint run or sag when using Graco Magnum ProX7?
    • B
      butlertimothyAug 29, 2025
      If your Graco Paint Sprayer is spraying paint that runs down the wall or sags, it's likely due to applying too much paint. Try moving the gun faster. You may need to choose a tip with a smaller hole size or a wider fan. Also, ensure the gun is far enough from the surface.

      Charles PetersSep 23, 2025
      If paint sprayed from your Graco Paint Sprayer runs down the wall or sags, it may be because the coat is going on too thick, so move the gun faster. Also, ensure the gun is far enough from the surface.
