<p>The device has a motor, in particular a driver and electric motors of a near-surface equipment housed over a linkage to a handle arrangement. A two-hand protective circuit has two actuators at the handle. For the start of the driver both actuators must be simultaneously in an operating end position. The first actuator (GB, GM) affects an intermediate spring element (F1) of an engine switch. The second actuator (H2,BA) is integrated into the handle. The first actuator is a tiltable grasp handle (GB) with several grasp positions. The engine switch (ms) is implemented as tracers. The engine switch contains a check element (FR), which is unlockable by the second actuator.</p> |
