Zusammenfassung:	A power tool includes an elongated shaft forming a handle and a tool head located at one end of the handle. The tool head includes a working element and a driven shaft configured to drive the working element. A powerhead located at an opposite end of the handle and includes an input shaft. A driveshaft is coupled between the tool head and the powerhead. The driveshaft has a first driveshaft portion rotatably driven by the input shaft and a second driveshaft portion coupled to the first driveshaft portion and the driven shaft. The second driveshaft portion is driven by the first driveshaft portion to transfer torque from the powerhead to the working element. One of the first driveshaft portion or the second driveshaft portion is constructed of a non-conductive material or both of the first driveshaft portion and the second driveshaft portion are constructed of a non-conductive material.
