Description
Overview:
This Trigger Interlock is a non-genuine replacement safety lever for Stihl TS410 and TS420 disc cutters. Made from durable polymer, it forms part of the throttle safety system in the top handle, preventing the throttle from engaging unless the interlock is deliberately pressed. Replacing a worn, cracked, or missing interlock restores smooth and secure operation, reducing the risk of accidental activation during cutting tasks. The component follows the geometry of the original to fit correctly within the handle assembly and work in conjunction with the throttle trigger and return spring. It is a direct replacement for OEM reference 4238 182 0800 and is suitable for routine maintenance, repairs, and fleet upkeep where dependable performance and straightforward fitting are important.
