摘要： A handheld work apparatus includes a drive motor, an operating-fluid tank and a motor carrier on which the drive motor is held. The operating-fluid tank has a first housing section and a second housing section. The first housing section is realized so as to be integral with the motor carrier. At least a portion of the second housing section is formed from light-transmitting material to permit discerning the fill level of the operating-fluid tank. The motor carrier has a light-transmitting light conductive element for conducting light into the operating-fluid tank.

摘要： A carburetor has a carburetor housing wherein an intake channel section is arranged. A fuel opening opens into the intake channel section. The carburetor has a fuel pump with a pump membrane delimiting a pump chamber connected to a fuel inlet. A pressure controller has a control membrane separating a control chamber from a compensation chamber. The control chamber is connected to a fuel outlet leading out from the carburetor. The compensation chamber is connected to a compensation connection. The carburetor housing has a carburetor body, a pump cover and an intermediate part arranged therebetween. The fuel inlet, the fuel outlet and the compensation connection are formed on the intermediate part. The fuel inlet, the fuel outlet and the compensation connection are arranged on the side of the carburetor that faces away from the combustion engine.
