  • Patent number: 10981292
    Abstract: 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.

  • Publication number: 20170002861
    Abstract: A bearing assembly for a drive shaft guided in a protective tube is provided with bearing tube segments arranged in the protective tube one after another in a longitudinal direction of the protective tube. The bearing tube segments are penetrated by the drive shaft. The bearing tube segments include bearing sections. The bearing sections are provided with a central bearing sleeve and support elements projecting away from an outer circumference of the bearing sleeve. The bearing sleeve is radially supported by the support elements on an inner circumference of the protective tube. The bearing section with its bearing sleeve and support elements is formed as one piece. The bearing tube segments have a length measured in a longitudinal direction of the protective tube and the sum of the lengths of the bearing tube segments is greater than 60% of a length of the protective tube.
