Quick Chain Tensioning (B)

The STIHL chain quick tensioning system (B) makes it very easy to tension the chain. Just release the sprocket cover and turn the knob to set the optimum tension. No tools needed.

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.

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.
