Original Makita Controller Complete — part 143291-1
Genuine Makita controller assembly (complete control module with PCB, connector block and mounting housing) designed as a direct factory-fit replacement for the DLS714 slide compound mitre saw. This unit restores the saw’s electronic motor control, speed/power regulation and safety interlock functions so the tool runs like new again.
Fits Makita DLS714 series (including DLS714 / DLS714Z slide compound mitre saws). The part 143291-1 is listed as the Controller Complete for the DLS714 and is shown in parts breakdowns alongside the later reference 140B40-9.
Simple to install in place of the original controller—matches factory connector locations and mounting points—so you can get the saw back to full operation without modifying the tool.
