  • Manually operated implement driven by an internal combustion engine
    Publication number: 20060137653
    Abstract: A manually guided implement driven by an internal combustion engine having a carburetor that is actuated by a throttle lever arrangement, which includes a throttle lever that is mounted in the implement so as to be pivotable about a pivot axis, and also includes a transmission element that operatively connects the throttle lever with the carburetor. The transmission element is an essentially rigid connecting rod that is mounted on the throttle lever and on an actuating lever of the carburetor.

  • Manually operated tool
    Patent number: 6955152
    Abstract: A manually operated tool such as a parting-off grinder, chainsaw or similar device has a tank housing which contains a fuel tank. The tool has an air cleaning unit, the tank housing being connected to the clean air side of the air cleaning unit via a bleed device. A simple design in which leaks are avoided results if a reservoir wall of the tank housing and a housing wall of the air cleaning unit are positioned adjacent to one another and the bleed device comprises a bleed opening which passes through the reservoir wall and the housing wall.

  • Anti-vibration element
    Publication number: 20050035511
    Abstract: An anti-vibration element for disposition between two components of a manually operated implement, especially a parting-off grinder, a chain saw, a suction/blower device, or the like, is provided. The anti-vibration element includes a spiral spring that is guided so as to be elastic in all spatial directions. In addition to the spiral spring, a rubber elastic damping element is provided that, relative to the plane of winding of the spiral spring, is more rigid in the axial direction than in the radial direction.

  • Manually operated tool
    Publication number: 20040261754
    Abstract: A manually operated implement such as a chainsaw, parting-off grinder or similar device is provided and has an internal combustion engine to drive a tool, an air cleaning unit and a tank housing. The tank housing is a cast part and a fuel tank is located in the tank housing. A simple, advantageous design of the tank housing is achieved when at least one housing part of the air cleaning unit is formed on the tank housing.

  • Manually operated tool
    Publication number: 20040248506
    Abstract: A manually operated implement, in particular a parting-off grinder or similar device is provided. The implement has a bracket which has a first end, which is fixed to the housing of the tool, and a second end to which is fixed a spindle which drives, for example, a metal cutting tool. The spindle is driven by a drive wheel via a belt drive. A bracket of high rigidity at low overall weight can be achieved if the bracket is designed as one piece and can be fixed to the housing in at least two positions.
