Description
Overview:
This Soft Start Circuit 110 V is a genuine Makita OEM component designed to restore smooth start-up performance on the Makita 5903R circular saw. It is an electronic module that limits inrush current and ramps the motor up to speed in a controlled way, helping to reduce mechanical shock and electrical stress. By easing the load on the motor, switch, brushes, and drivetrain, it supports reliable cutting from the first trigger pull and helps extend the service life of the tool. Built for heavy site use on 110 V supplies, it offers consistent performance with the 5903R, maintaining steady power during start-up and improving user control. Supplied as a direct replacement for the original Makita part number 631247-1.
