QuickStop Super Chain Brake (Q)
The additional braking system for extra safety. Users can trigger the chain brake directly at the rear handle. The chain stops in seconds whenever the user lets go of the rear handle and whenever there is sufficiently strong kickback or when the front hand guard is activated. This unique safety feature ensures even more user protection in all working positions.
The STIHL EC motor is extremely energy efficient, lightweight and compact. It runs quietly and generates very low vibrations, which ensures you and your machine can work comfortably for prolonged periods of time.
