Abstract

A hand-held power tool system has a hand-held power tool, a guard unit, and a guard anti-rotation lock unit configured to prevent rotation between the guard unit and the hand-held power tool in a case where a tool of the hand-held power tool breaks during intended operation. The guard anti-rotation lock unit also is configured to prevent rotation between the guard unit and the hand-held power tool at a same time as the guard unit is attached to the hand-held power unit, when the guard unit is in a working position. Preferably, the guard anti-rotation lock unit is at least partially located on a closing unit which includes a clamping band and a pivotable lever. The anti-rotation lock unit preferably includes an anti-rotation lock element provided on the lever.
