Makita 631612-4 Spare Part - SOFT START CIRCUIT 110V LS10

Original Makita soft-start circuit board — part number 631612-4 — designed for 110V Makita table/mitre saws to restore smooth, controlled motor startup.

What it is: a compact printed-circuit module with fixed wiring leads and mounting points that replaces the saw’s failed soft‑start electronics. The board limits inrush current and ramps motor voltage on switch‑on to reduce start‑up torque, minimise nuisance tripping on 110V supplies, and cut mechanical/electrical stress on brushes, bearings and gears — helping extend the life and accuracy of the tool. If you’re ordering Makita parts for a repair, this is the component to check.

Fits (example models): Makita 2704 (260 mm table saw) and the LH1040 / LH1040F mitre/table saw series — listed as a direct replacement for those machines.

Notes for the repair: supplied as a single PCB (P/N 631612-4) with pre‑wired leads for direct integration into the existing control housing; replace this board if the saw jerks on start, trips breakers on power-up, or shows degraded startup performance. Ideal for technicians and DIYers who need reliable power tool parts for repairs.
