For performing a control method, the hydraulic control system is configured to deliver pressurized hydraulic fluid to 10 the actuator, the hydraulic fluid being pressurized at most to a predetermined maximum pressure, and the control system is adapted to regulate the predetermined maximum pressure based on the determined position. According to an example, the moveable device is a boom of a working machine. According to a further example, the actuator is a hydraulic cylinder 15 or motor.1/6 0 x co CC N o P 2 5 2 i g
