Description
4243 708 6202 STIHL Notched Quadrant – Genuine OEM Angle Drive Part
The STIHL Notched Quadrant (4243 708 6202) is a genuine OEM angle adjustment component designed for select STIHL long-reach hedge trimmers and KombiSystem attachments equipped with adjustable angle drive assemblies. This notched quadrant works as part of the locking mechanism that allows the gear head to be positioned securely at multiple cutting angles.
Over time, the notched quadrant may wear due to repeated angle adjustments, vibration, heavy-duty trimming, or debris contamination. A worn or damaged quadrant can cause improper locking, loose angle positioning, or unsafe gear head movement. Replacing it with the correct OEM part restores secure angle engagement and smooth adjustment operation without replacing the complete gear head assembly.
Manufactured to STIHL factory specifications, this genuine notched quadrant ensures precise fitment, reliable locking performance, and long-term durability under professional operating conditions.
