Description
Overview:
The Stop Buffer for Stihl is a Genuine Part (OEM) designed to control impact and vibration within the hedge trimmer drive system. Made from a durable rubber elastomer, it absorbs shocks during cutting to protect the gearbox and blade drive, reducing wear and helping the machine run smoothly. This buffer is identified by MPN 4237 790 9700 and is used on popular Stihl hedge trimmers such as the HS 81 R and HS 81 RC. It is a direct-fit replacement to original specification, making it suitable for routine servicing or restoring performance on tools that have become harsher or noisier in operation. Built for both professional and domestic use, it supports reliability, comfort, and longer service life of your equipment.
