Description
Overview:
This controller unit is an electronic engine management module for Stihl fuel-injected disc cutters, including the TS 480i and TS 500i. It regulates key running parameters so the machine starts reliably, idles cleanly, and maintains consistent power under load. Housed in a robust black plastic body with potted internal electronics, it is built to cope with dust, vibration, and moisture typically found on site. The unit connects via a multi-pin plug and mounts to the standard fixing points, making it suitable as a like-for-like replacement when the original module fails. Identified by part number 4250 400 4701, it helps keep your cutter performing as intended for concrete, stone, and masonry cutting tasks.
