Description
Overview:
This Start Stop System Big is a genuine Nilfisk replacement assembly for selected compact pressure washers, including the C 120.7-6 and C 120.7-6 PCA. It controls the automatic start and stop of the motor based on trigger use, helping the machine run only when needed. Built from durable, high-quality materials, typically a tough polymer body with metal internal components, it is designed for long service life in wet, high-pressure environments. As a direct replacement for OEM No. 31001131, it restores correct operation when the original unit has worn or failed. Correct start/stop control reduces unnecessary motor run time, limits wear on the pump and seals, and improves overall efficiency, making routine cleaning tasks smoother and more reliable.
