Beschreibung
Zusammenfassung:	The invention relates to a portable handheld work apparatus such as a motor-driven chain saw, a cutoff machine, a brushcutter or the like. The work apparatus includes an internal combustion engine (1) mounted in a housing (2) which drives a work tool via centrifugal clutch (3). The centrifugal clutch (3) includes a carrier (5) driven by the engine (1). The carrier (5) has rpm-dependent displaceable centrifugal weights (6) which are displaceable against a return force and come into contact engagement against a contact wall (7) of an output part (8) so as to transmit-torque. A rotationally-elastic damping element (11) is arranged between the output part (8) and an intermediate element (10) connected to the tool (4) so as to rotate with the intermediate element (10).
