摘要： A protective cover for a cutting wheel of a hand-held cut-off machine driven by an internal combustion engine has a circumferential wall and two opposed sidewalls adjoining the circumferential wall. The circumferential wall and the two sidewalls are a monolithic component made of cast light metal. The circumferential wall in a circumferential direction has at least over sections thereof a first integral thicker portion. The two sidewalls are thinner than the first integral thicker portion. Preferably, the protective cover is made of diecast magnesium.

摘要： A protective cover of a hand-held cut-off machine has a cover member having an interior. At least two injection nozzles for spraying a cooling liquid into the interior are arranged on the cover member. A supply line for supplying the cooling liquid to the at least two injection nozzles is provided. A bow is arranged outside of the cover member. The supply line has a line section that extends from a first injection nozzle to a second injection nozzle through the bow.

摘要： A handheld work apparatus has an internal combustion engine (14, 44, 94) which has a crankshaft (15, 45, 95) which, in turn, drives a work tool of the work apparatus. The work apparatus has a first component group which includes the crankshaft (15, 45, 95) and which is driven in a first rotational direction (10, 40, 70, 90). In order to hold the gyroscopic forces low which act during operation, the work apparatus has a second component group which includes the work tool and which is driven in a second rotational direction (11, 41, 71, 91) opposite to the first rotational direction (10, 40, 70, 90).
摘要翻译： 手持式作业装置具有内燃机（14,44,94），所述内燃机具有曲轴（15,45,95），所述曲轴又驱动所述作业装置的作业工具。 工作装置具有包括曲轴（15,45,95）并沿第一旋转方向（10,40,70,90）驱动的第一组件组。 为了保持在操作期间作用的陀螺力低，作业装置具有包括作业工具的第二构件组，并且与第一旋转方向相反的第二旋转方向（11,41,71,91）被驱动 （10，40，70，90）。
