Abstract

Die Erfindung betrifft eine zumindest teilweise schlagende Handwerkzeugmaschine mit einem pneumatischen Schlagwerk (20), das ein in einer Führung (21) hin und her bewegbares Schlagelement aufweist, und mit einer Bremseinrichtung (30) für das Schlagelement, die wenigstens ein am Schlagelement bremswirksam anlegbares Bremselement aufweist. Zur Verbesserung einer derartigen Handwerkzeugmaschine ist das wenigstens eine Bremselement als Schwenkhebel (31) ausgebildet, der über eine am Schlagelement angeordnete Steuerkontur (25) schwenkgesteuert ist.
