Description
Overview:
This Trigger Interlock is a genuine Stihl safety component for petrol chainsaws, designed to prevent accidental throttle engagement. Made from durable, impact‐resistant polymer in Stihl's high‐visibility orange, it sits in the top‐handle control area and ensures the throttle trigger only operates when the interlock is correctly depressed. It is an OEM part identified by MPN 1129 182 0800 and is suitable for various compact and professional top‐handle saws, including the MS 191 T and MS 200 T. Fitting a new interlock restores positive, reliable lockout action where the original has worn, cracked, or been lost. Built to withstand oil, fuel, vibration, and regular use, this genuine part maintains the saw's safety system as intended by the manufacturer.
