Why is my Graco 232751 Paint Sprayer motor hot and running intermittently?
If your Graco Paint Sprayer motor is hot and runs intermittently, it's likely experiencing a thermal overload. This can happen if the vent holes in the shroud are clogged, so clear them. Another cause could be using an extension cord that's too long or not heavy enough gauge, so replace the cord. Using an unregulated electrical generator with excessive voltage can also cause this, so use a generator with a proper voltage regulator. Lastly, operating the sprayer at high pressure with a small tip can cause frequent motor starts and excessive heat, so decrease the pressure setting or increase the tip size and move the sprayer to a cooler location.
What to do if my Graco 232751 Paint Sprayer only dribbles?
If the Graco Paint Sprayer pump cycles, but paint only dribbles or spurts when you pull the trigger, the pressure may be set too low; try increasing it. Another possibility is a clogged spray tip; clean it. The spray tip might also be too large or worn, in which case you should replace it.
Why is my Graco paint sprayer building circuit breaker opening?
If the building circuit breaker opens after your Graco paint sprayer operates for a few minutes, or as soon as it's plugged in, there might be too many appliances on the same circuit, so unplug some. The extension cord could be damaged, too long, or not heavy enough gauge; test it with a working device and replace if necessary. A damaged sprayer electrical cord could also be the cause; inspect for broken insulation or wires and replace if needed.
