摘要： A handheld work apparatus such as a bed redefiner or edger has a handle for guiding the work apparatus over the ground. The apparatus also includes a drive motor which drives a tool in rotation. During operation, the apparatus is moved over the ground by the operator in a direction of movement. The tool is covered at least partially by a protective hood and a sliding skid is arranged on that end of the protective hood located at the front in the direction of movement. The sliding skid has an abutment surface for a flexible spray guard fixed to the protective hood. The spray guard is fastened to the protective hood in its fastening region located at the front viewed in the direction of movement. The spray guard is movable in its protective region located at the rear viewed in the direction of movement.

摘要： A carburetor for a hand-guided power tool has a carburetor housing and a carburetor rotor supported rotatably in the carburetor housing about an axis of rotation. A needle is disposed on the carburetor rotor and projects into a fuel opening of the carburetor. An adjusting element is operatively connected to the needle so as adjust a position of the needle relative to the carburetor rotor. The adjusting element has an engagement contour that is to be engaged by a tool for adjusting the adjusting element. A securing contour that is fixedly connected to the carburetor rotor is provided. The securing contour, at any point of the securing contour, has a spacing to the axis of rotation of at least approximately 10 mm.

摘要： A carburetor has a housing wherein a control drum is rotatably mounted. A section of an intake channel is formed in the carburetor. A subsection of this section is formed in the control drum. The control drum controls the free flow cross section of the intake channel. A fuel opening is connected to a fuel chamber via an unbranched fuel channel which opens into the subsection of the intake channel. A simple configuration of the carburetor is achieved by the carburetor including an electrically actuated valve which controls the flow of fuel through the fuel channel. For a method for operating an internal combustion engine with a carburetor, a temperature (T) is determined before or during the starting of the engine and that the flow of fuel through the fuel channel during the starting of the engine is controlled in dependence upon the temperature (T).
