HYDRAULIC SYSTEM General The task of the hydraulic system is to operate the ma- chine’s functions by means of hydraulic pressure and fl ow. The system consists of hydraulic pump, tank, cooler, hydraulic motor, hydraulic cylinders, fi lters and valves of various kinds. Hoses or pipes connect the components with each other. Valves are used to control the hydraulic system’s pressure, volume rate of fl ow and direction. Pressure control valves limit or reduce the pressure to the value required.

ELECTRIC SYSTEM General The electric system consists of a high-voltage circuit and a low-voltage circuit. High-voltage circuit High-voltage is used as a power source for both the electric motor and the low-voltage circuit. An automat- ic phase rotation change-over switch ensures that the electric motor has the correct rotation direction. Power supply The power supply from the main must be suffi ciently powerful and constant to ensure that the electric mo- tor runs without problems. Too high
