Why does my Master MFG Revolt pump cycle when not spraying?
- MMrs. Alicia SantanaJul 29, 2025
If the Master MFG Paint Sprayer's pump cycles even when you're not spraying, it could be due to several reasons. You might have a leak in the system, so try tightening any leaking hose clamps or fittings, and if necessary, replace the spray gun. Low voltage could also be the culprit, so check the voltage. Trapped air in the system can cause this issue as well; try purging the air from the system. Additionally, a faulty pressure switch could be the cause, so consider replacing it. Ensure the pump is mounted on a rigid surface. Finally, check for and tighten any loose fasteners on the pump head.
