Overview:
The Start Stop System (OEM No. 31000515) is a Genuine Nilfisk part for the Nilfisk C 110.4-5 PCD X-TRA pressure washer. It controls the automatic motor start when the trigger is pulled and stops the motor when released, helping to prevent unnecessary running, reduce wear, and save energy.
