Abstract

The invention relates to portable handheld work apparatus including a brushcutter, edge cutter or the like. The work apparatus has a drive motor (1) and a cutting tool (2) driven by the drive motor. The work apparatus includes a guide tube (3) for guiding a drive shaft (4) as well as a handle (5) fixed on the guide tube (3). The drive shaft (4) connects the cutting tool (2) to the drive motor (1). The handle (5) is in the form of a handle bracket (8) and can be pivoted about a pivot axis (7) lying transversely to the longitudinal axis (6) of the guide tube (3) for adjusting the distance (a) of the handle to the guide tube (3). A spring action handle bracket holder (22, 23) is mounted between the handle bracket (8) and the guide tube (3). The handle bracket holder is especially vibration dampening and extends with a component in the direction of the longitudinal axis (6).
