HYDRAULIC SYSTEM General The task of the hydraulic system is to operate the machine’s functions by means of hydraulic pressure and ﬂow. The system consists of hydraulic pump, tank, cooler, hydraulic motor, hydraulic cylinders, ﬁlters and valves of various kinds. Hoses or pipes connect the components with each other.
ELECTRICAL 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 automatic phase rotation change-over switch ensures that the electric motor has the correct rotation direction.

MACHINE´S SAFETY EQUIPMENT General Identity code The remote control and the machine are connected by means In this section the machine’s safety features and their function of a pre-programmed ID code. The ID code ensures that the are explained. Concerning inspection and maintenance, see right remote control is used for the right machine.
MACHINE´S SAFETY EQUIPMENT Mechanical protection Automatic phase rotation relay The automatic phase rotation relay prevents the electric motor starting with the wrong rotation direction thus causing mechanical damage. Motor protection To prevent overloading, the motor is equipped with bimetallic relays in the motor linings that disconnect the power to the motor if it gets too hot.
