Abstract
A manually operated implement such as a chain saw, a parting-off grinder or similar device has an internal combustion engine to drive a tool and a handle arrangement to operate the implement. The handle arrangement is connected to the internal combustion engine via a vibration damping system, the vibration damping system comprising at least one anti-vibration element. In order to achieve good vibration damping and sufficient operational rigidity in all operating ranges, in at least one direction of vibration in a predetermined frequency range the anti-vibration element has a first characteristic curve in a first state and a second characteristic curve in a second state and the anti-vibration element can be switched between the first state and the second state.
