Central Lubricating

Design and function

3659733

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 engines are running. All greasing points connected to the system are greased at regular intervals.

The automatic greasing is interrupted when the engines are stopped with the idle timers.

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

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

Lube cycle / Pause period

To set length of lube cycle, alter the code number in window (1)

To set length of pause period, alter code with switch in window (2)

Lube cycle manual lubricating (optional)

To set length of lube cycle, alter the code number in window (3)

The facia on the SPC controller has coding switches that can be used to set the length of lube cycle and pause period as listed on the setting scales (3, Fig. 3-126:)

If a fault occurs, BCS gives a warning on the screen (Fig. 3-127:). Actuat the "Reset" button (5, Fig. 3-126:) 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 (storage-programmable control)

Operating Instructions

Inspection and servicing

The two grease pumps (2, Fig. 3-128:) pump grease through the greasing lines to the main grease distributors of the superstructure.

The grease pump (1, Fig. 3-128:) pumps grease through the greasing lines to the undercarriage.

The control elements of the lubricating system (undercarriage) are installed on the panel (21, Fig. 3-129:).

The control elements of the lubricating system (superstructure) are installed on the panel (3, Fig. 3-129:).

As soon as the grease container is empty, the BCS (Fig. 3-131:) 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.
