A handheld power tool () comprising at least one orientation sensor () is provided. The handheld power tool () is operatively connected to a controller () and said controller () is configured to receive orientation data from the at least one orientation sensor (), wherein the orientation data comprises information associated with an orientation of at least a portion of the handheld power tool () and to determine operational data based on the orientation data, said operational data representing work performed using the handheld power tool (). The operational data is determined by determining the orientation of the power tool based on the received orientation data from the at least one orientation sensor ().

Handheld power tool

A trimmer head arranged to be driven to rotate a trimmer line, where the trimmer head includes a housing and an inner body connected to a trimmer line spool. The inner body is arranged to be movable relative the housing so that a trimmer line spooled around the trimmer line spool is released and pulled out by a centrifugal force caused by the rotation of the trimmer head, thereby allowing feed of the trimmer line. The trimmer further includes drive means for driving the trimmer head to rotate, and the trimmer is arranged to cause a relative movement of the inner body relative the housing by changing the rotation speed of the trimmer head.
