Summary:Control equipment for guiding a drill rod, the control equipment including a frame (6) and two guide jaws (8a, 8b) provided with guide surfaces and mounted movably in relation to the frame (6), between which guide jaws the drill rod (5) is to be set during drilling, and actuators (9) for moving the guide jaws (8a, 8b) in relation to the drill rod (5). The control equipment comprises synchronization means coupled between the guide jaws (8a, 8b) such that the guide jaws (8a, 8b) always move in opposite directions to one another and at the same speed, and a detector which detects that the guide surfaces of the guide jaws (8a, 8b) are in contact with the drill rod (5).
