Abstract
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 ( ) mounted in a housing ( ) which drives a work tool via centrifugal clutch ( ). The centrifugal clutch ( ) includes a carrier ( ) driven by the engine ( ). The carrier ( ) has rpm-dependent displaceable centrifugal weights (6) which are displaceable against a return force and come into contact engagement against a contact wall ( ) of an output part ( ) so as to transmit-torque. A rotationally-elastic damping element ( ) is arranged between the output part ( ) and an intermediate element ( ) connected to the tool ( ) so as to rotate with the intermediate element ( ).
