  • Patent number: 9517555
    Abstract: A battery operated handheld power tool, comprising a working tool assembly (20), a handle assembly (10) and an elongate tubular rod (30). The working tool assembly (20) comprises a motor housing (26) having a first inner space (27), comprising an electric motor (21) with a fan (25). The first inner space (27) is connected to the exterior of the working tool assembly (20) by means of at least one air outlet (28). The handle assembly (10) comprises a second inner space (19) in which a control unit (15) is positioned, the second inner space (19) being in flow communication with the exterior of the handle assembly (10). The elongate tubular rod (30) defines an air guiding channel (33), in flow communication with the first inner space (27) and the second inner space (19).

  • Publication number: 20140215835
    Abstract: A hand held battery powered cutting tool is provided. The tool the (1) comprises a handle portion (30), a cutting assembly (10) which cutting assembly comprises a cutting means carrier (12) arranged to rotate therewith a cutting means (13) about a first axis (A1) of rotation, and an electric motor (11) arranged to rotate an output shaft about a second axis (A2) of rotation. The tool furthermore comprises an elongate rod (20) interconnecting the handle portion (30) and the cutting assembly (10). The elongate rod (20) has a lower end portion (21) arranged proximal to the cutting assembly (10). The lower end portion has an extension direction essentially coinciding with the first axis (A1) of rotation. The second axis (A2) of rotation is located behind the first axis (A1) of rotation when the tool (1) is in a working position.
