Abstract
The invention relates to a hammer and/or hammer drill acting as a breaker, having a drive, a hammer mechanism driven by the drive, and a crank device disposed in the force flow path between the drive and the hammer mechanism and coupled to an element of the hammer mechanism for transforming a rotary motion of the drive into an oscillating translation motion of the element of the hammer mechanism. A collecting device for collecting lubricant is provided above the hammer mechanism relative to a vertical operating position. The collecting device may be a collecting tank open at the top and defined by a partition of the housing and a separating floor. A connecting rod of the crank device may extend through a cutout in the separating floor. Lubricant collects above the separating floor can be delivered again and again into the interior of the housing by a delivery element.
