How to start Graco 390 Electric Airless Sprayer Paint Sprayer if motor won’t operate?
- HHarold FletcherJul 26, 2025
To resolve a motor that won’t operate on your Graco Paint Sprayer, first, slowly increase the pressure setting to see if the motor starts. The motor won't run if the pressure control knob is set at minimum. If this doesn't work, the spray tip or fluid filter may be clogged.
