A safety device on a power saw which is provided with two handles, especially for a power chain saw. The saw has a brake which engages a drive member of the cutting tool of the saw under the effect of a force retainer; the brake is held in the ineffective or inoperative position by a stop which is actuated by operating elements associated with the two handles. The stop is locked in its locking position and is releasable by means of an adjustment device which is driven by an energy source supplied by the engine of the saw, and is controlled by a control device which is connected to the operating elements which are embodied as key or contact switches.
