OPERATING INSTRUCTIONS RH 90 C E Inspection and servicing CENTRAL LUBRICATING
Function
Design
The grease is pumped by the pump (2, Fig. 3-86:) via greasing lines from the grease container to the main distributors on the superstructure.
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.

The control elements of the lubricating system are installed on the panel (3, Fig. 3-87:)
Fig. 3-85:
If a fault occurs, BCS gives a warning on the screen (2, Fig. 3-85:). Actuate the "Reset" button in the control column to eleminate the fault. Is this is not possible, call in servicing personal. For further information on the function and setting refer to the "Technical Handbook – SPC (Stored Program Control").
Fig. 3-87:
As soon as the grease container is empty, the BCS (Fig. 3-85:) gives a warning signal. In the event of a fault, the "dumping" function is switched off automatically after 15 min. Work can be continued when the grease container is filled with grease.
