Abstract

A hydraulic system, rock drilling rig, and method for limiting output performance of a hydraulic drilling actuator (Ha) temporarily under execution of a safety function feature of a hydraulic system (HS). The output performance is limited by limiting produced hydraulic fluid flow in a hydraulic circuit (CL, OL) of the hydraulic drilling actuator, whereby restricted magnitude of the fluid flow is produced at a hydraulic pump. This way a restricted operation mode (ROM) is enabled and is controlled by a control unit (CU) .
