CENTRAL LUBRICATING Design

The excavator is equipped with an automatic central lubricating system which provides grease regularly to all greasing points except those mentioned in the "Lubricating chart - Grease".

The central lubricating system is activated when the electrical system is switched on with the keyswitch and the electric motor is running. All greasing points connected to the system are greased at regular intervals.

The central lubricating system is controlled electro-hydraulically by the programmable SPC contoller.

The SPC is located in a switch box underneath the cab.
