- Side chain tensioner The tensioning screw can be found on the side of the chain saw through the sprocket cover. This removes the need for contact with the sharp saw chain.
- QuickStop Super Chain Brake 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.
- Toolless filler cap The tank can be filled quickly and easily using the toolless filler cap.
- STIHL Electric Motor (EC) The STIHL electric motor (EC) is extremely energy efficient, lightweight and compact. It runs quietly, generates very low vibrations and does not require servicing.
- Hand guard Ensures clear feedback when engaging or disengaging the chain brake.
