Embodiment Construction

[0023] FIG. 1 shows an example of a hedge trimmer 1 as a hand-held implement. However, the hand-held power tool can also be a clearing cutter, tree feller or the like. The hedge trimmer 1 has a motor housing 2 in which a drive motor 50 schematically shown in FIG. 1 is arranged. The drive motor 50 is designed as an electric motor. The motor housing 2 has a connecting cable 3 for powering the drive motor 50 . The hedge cutter 1 has a guide rod 5 . The motor housing 2 is fastened to a first motor-side end 40 of the guide rod 5 . Adjacent to the motor housing 2 , a handle 4 for supporting the hedge trimmer 1 is provided on the guide rod 5 . The handle 4 surrounds the guide rod 5 . The guide rod 5 is surrounded over part of its length by a handle hose 55 on which the operator can hold the hedge trimmer with his other hand. But it is also possible to fix an arc handle on the guide bar 5 to support the hedge cutter 1. A handle frame may also be suitable, to which one or two ha...

Description

technical field [0001] The invention relates to a hand-held work implement, such as a clearing cutter, hedge cutter, hochentaster or the like. Background technique [0002] A tree feller is known from DE 196 19 081 A1, in which a guide rod connects the housing of the power tool to the transmission housing of the power tool, in which a drive motor is arranged. Tools are set on the transmission case. The transmission housing is clamped to the guide rod via a clamping connection. In this case, the transmission housing is electrically conductively connected to the guide rod. [0003] When working with a power tool with a driven tool, the wires can be damaged or cut by the tool. Electrical installations have safety devices that interrupt the power supply if the wires are damaged or cut, thereby avoiding injury to the operator. In rare cases, however, this safety device may also be damaged or malfunction. Contents of the invention [0004] The object of the present inventio...
