  If your Graco Construction Equipment engine or sprayer won’t start, there are several potential causes: * The engine switch might not be turned on. Ensure the engine switch is on. * The gas tank may be empty. Refill the gas tank. * The engine oil level could be low. Try starting the engine; if the light on the rear of the engine glows, replenish the oil. * The spark plug cable might be disconnected or the spark plug damaged.

  If you're experiencing spitting from the gun of your Graco Construction Equipment, here's what might be happening: * There could be air in the fluid pump or hose. Check for loose connections at the pump intake and tighten them. Then, prime the pump. * The tip might be partially clogged. Clear the tip clog. * The fluid supply may be low or empty. Refill and prime the pump. Check the fluid supply often to prevent running the pump dry. * Dried paint particles from a poorly cleaned suction tube assembly could be the issue. Remove and clean the suction tube. During normal flushing, remove and clean the suction tube assembly separately to prevent further clogging.
