Beschreibung
Zusammenfassung:	A method and an equipment for controlling the operation of a rock drilling apparatus, which rock drilling apparatus comprises a percussion device for producing impact energy to a tool of the rock drilling apparatus, a rotating device for rotating the tool in a drill hole, a feeding device for feeding the tool in the drill hole and a flushing device for supplying flushing agent through the tool and the bit for flushing loose drilling waste from the hole. The feed force and the percussion power are determined and the relation between the feed force and the percussion power is adjusted to a targeted operation area within an upper and a lower limit.
