How to fix slow application speed on a Graco 254986 Paint Sprayer?
- WwmcdonaldSep 8, 2025
If your Graco Paint Sprayer's application speed is slow, consider the following: * The material might be too thick. Thin the material. * The nozzle might be too small. Change to a larger nozzle. * Too much air might be used. Partially close the gun air valve to reduce airflow. * The pump hose might be worn. Replace the hose. * The gun might be plugged or dirty. Clean the gun. * The hose might be kinked. Unkink the hose. * The gun adjustment might be set too low. Increase the flow adjustment with the flow adjustment nut. * There might be too many items on the same circuit. Unplug other items from the circuit. * The extension cord might be too long or the wrong gauge. Use a different extension cord.
