Abstract
The invention is directed to an arrangement for actuating a braking device for bringing a motor-driven work tool of a work apparatus to standstill. The braking device is actuated by a brake lever and the brake lever is connected to a pivotably journalled throttle lever via a first actuator. The throttle lever controls the carburetor of the engine driving the work apparatus via a second actuator. In order to bring the work tool rapidly to standstill in idle, the second actuator is attached to a drag lever which is pivotable relative to the throttle lever. After passing through an idle movement path, the throtle lever takes the drag lever along via a follower in a pivot direction.
