Questions and Answers

    Why is there excessive surging from my Graco EM 490 Paint Sprayer's spray gun?
    • M
      Mark MasseySep 12, 2025
      If you're experiencing excessive surging from the spray gun of your Graco Paint Sprayer, several factors could be the cause. Check if the spray tip is plugged and disassemble and clean it if necessary. The spray tip might also be too big or worn, so consider changing it. If the paint is too viscous, thin it out. Lastly, ensure you're using the correct type of hose—a minimum 15 m (50 ft) grounded, flexible hose (wire braid hose is unacceptable).
