In order to design a motor chain saw with a chain brake device releasable as a back kick brake and as a coasting brake comprising a tension lever (2), movable with respect to the housing of the motor chain saw, which can be moved between a brake position (B) and a ready position (b), a release lever (19) which can take up a coasting brake position (A) and a disengaging position (f), in combination with a supplementary brake device known as a coasting brake, it is proposed that the tension lever (2) is placed linearly slidingly movable with respect to the housing of the motor chain saw and that the release lever (1) is placed slidingly movable with respect to the tension lever (2), whereby both axles of the sliding movement are parallel to each other.
