Abstract

A handheld work apparatus has a motor unit comprising a drive motor. The drive motor drives a tool of the work apparatus, for example a saw chain. The apparatus has a grip unit with a handle that is vibrationally decoupled from the motor unit via an antivibration element. The antivibration element is connected to a first component of the grip unit via a holding device and a second component of the motor unit via a holding element. Arranged in the connection of the first component to the second component through the antivibration element is a predetermined breaking point formed in a third component that is replaceable independently of the first component and the second component. The strength of the connection of the first component to the second component through the antivibration element is lowest at this predetermined breaking point.
