Abstract

L'invention concerne une machine-outil portative (100) munie d'une unité d'entraînement qui présente au moins une boîte de vitesses pouvant être commutée entre au moins deux rapports différents, un mécanisme de percussion qui peut être activé pour l'exécution d'un mode percussion étant associé à l'unité d'entraînement. Une unité de changement de vitesse (205) permet de commuter la boîte de vitesses pouvant être commutée entre au moins deux rapports différents et/ou d'activer/désactiver le mécanisme de percussion. Une interface de communication (1050) est conçue pour communiquer avec une unité de guidage de l'utilisateur (115) pouvant être actionnée par un utilisateur, et est configurée pour recevoir de l'unité de guidage de l'utilisateur (115) des instructions de commutation de la boîte de vitesses spécifique à l'utilisation entre les deux rapports différents et/ou d'activation/désactivation du mécanisme de percussion.
