Description
Overview:
The Trigger Interlock is a genuine Stihl OEM safety component that sits in the top handle assembly of your chainsaw. Made from durable, oil‐ and impact‐resistant polymer in a precision‐moulded form, it works with the throttle trigger to prevent accidental activation, so the saw only runs when held correctly. This replacement suits a wide range of Stihl machines, including the MS 231 and MS 261, and is identified by MPN 1125 180 1703. It restores safe operation on professional and domestic saws used for felling, snedding, logging and general property maintenance. Designed for a direct fit and consistent performance, it helps maintain the original safety standard of your Stihl chainsaw for dependable everyday use.
