发明名称 HAND-HELD IMPLEMENT
摘要 A handheld work apparatus has a drive motor which drives a work tool in rotation via a belt drive. The belt drive has at least one first, driving pulley and at least one second, driven pulley. Between the first pulley and the second pulley there acts at least one drive belt for transmitting the drive torque. A second pulley is connected to the tool for conjoint rotation. The rotational speed of the second pulley is less than the rotational speed of the first pulley during operation. The work apparatus has a brake unit which acts on the first pulley. The belt drive includes at least one redirection roll. During braking, at least one redirection roll bears on the tight side of each drive belt which acts between the first pulley and the second pulley. This allows a simple structure and safe braking of the work tool.
