Why is my Graco Magnum ProX7 Paint Sprayer motor hot and running intermittently?

If the motor of your Graco Paint Sprayer is hot and runs intermittently (not due to thermal overload), ensure the vent holes in the enclosure are clear of obstructions and overspray, and keep the sprayer open to air. Replace the extension cord if it is too long or not a heavy enough gauge. If using an unregulated electrical generator, ensure it has a proper voltage regulator (120VAC, 60 Hz, 1500-Watt). If the sprayer was operated at high pressure with a very small tip, decrease the pressure setting or increase the tip size.
