Description
Overview:
The Trigger Interlock for Stihl TS400 is a Genuine Stihl part that forms a key part of the saw's throttle safety system. Fitted within the trigger assembly, it prevents unintended throttle engagement so the machine only accelerates when the operator has a secure grip. Built from durable, workshop-grade plastic suited to dusty and high-vibration environments, it is designed for long service life on professional and DIY cut-off saws. This OEM component offers the correct geometry for smooth operation and reliable return. For easy identification and ordering, it carries the Manufacturer Part Number (MPN) 4223 182 0800. Purpose-made for the Stihl TS400 (also TS 400), it is a direct replacement for worn, cracked, or missing interlocks and helps maintain safe, compliant operation.
