Abstract
A rock drill machine with a feed leg. The feed leg is attached to the rock drill machine with one end and rests on a support with another end. The feed leg is configured to feed the rock drill machine in a drilling direction and to interrupt feeding of the rock drill machine in the drilling direction. A control regulates the feed leg and a starter activates the rock drill machine. The control is provided on a rear handle in close proximity to the starter such that the control and the starter can be reached at the same time with one hand. Hereby, it is possible, with one hand, to activate and interrupt activation of the rock drill machine respectively, and simultaneously regulate the feed leg to feed the rock drill machine in the drilling direction and interrupt the feeding of the rock drill machine in the drilling direction.
