摘要： The invention relates to a portable, handheld work apparatus such as a chain saw having a handle (5, 7) to guide the work apparatus (1) and having an air-cooled, mixture lubricated combustion engine (10) arranged in a casing as a drive for a work tool (3). The cylinder (11) has a combustion chamber (13) formed therein to which an air/fuel mixture is supplied. The air/fuel mixture is ignited by a spark plug (23) which projects into the combustion chamber (13). An ignition control (30) triggers a spark in dependence on the angular position of the crankshaft (15). A temperature sensor (34, 45, 55) is provided to control the cylinder temperature. The temperature signal of the temperature sensor (34, 45, 55) is connected to a power control (40). When a predetermined temperature is exceeded, the power control (40) changes the operating parameters of the combustion engine (10) in such a manner that the power of the combustion engine (10) is changed.

摘要： A hand-guided power tool has a drive motor and a drive element connected to and driven by the drive motor. A working tool is connected to the drive element and driven by the drive element. A braking device is correlated with the drive element, wherein the braking device in a first state, in which the braking device is applied, blocks the drive element and in a second state, in which the braking device is released, releases the drive element so that the drive elements can rotate freely. The braking device has a brake lever and a sensor that detects the first and second states of the braking device. A control unit is provided, wherein an output signal of the sensor as a state signal of the first state or the second state is supplied to the control unit. The control unit, based on the state signal, controls devices of the power tool.
