Abstract
An electro-mechanical brake in a motor saw requires electric energy for the operation of the brake. This energy can, according to the invention, be surplus energy in the ignition system of the saw. Surplus energy exists usually only when the r.p.m. exceeds a certain value. A capacitor is charged by current from the system and is prepared to discharge through a coil to actuate the brake on a signal from a kickback sensor.
