Why is my Graco Paint Sprayer motor hot and running intermittently?
If your Graco Paint Sprayer motor is hot and runs intermittently, consider these factors: * Avoid operating the sprayer at high pressure with small tips, as this can cause low motor RPM and excessive heat build-up. Decrease the pressure setting or increase the tip size. * Ensure the ambient temperature is no more than 32°C and the sprayer is not in direct sunlight; move it to a cooler, shaded area if necessary. * Turn off the sprayer and relieve fluid pressure whenever you stop spraying for an extended period.
