    Abstract: A safety system for power chain saws including two flanges which are mounted on a hand guard frame on the left and right sides. The flanges point toward the rear and trigger the chain brake in the event of the hand slipping laterally and impacting with sufficient force. A further safety system includes a hand lever which is attached to the handle. This mechanism permits starting up of the saw only if the hand lever is pressed against the grip.
