Original Makita Controller — part no. 631595-8 — direct replacement for the Makita PW5000C wet-stone polisher. This compact controller/regulator is the factory-style electrical control used on the PW5000C to manage incoming voltage and restore smooth motor response and reliable on/off behavior.

Made to the same fit and specification as the original Makita component, the 631595-8 ships as a single controller unit and installs in place of the worn or damaged regulator assembly in PW5000C housings (check your tool’s type plate to confirm PW5000C compatibility).
