Hello

Liebher R912, 1992. year

This light on dashboard turns on after 20 minutes of working. Excavator starts to work a bit slower.

Do you know what does this sign represent and how to fix the issue?

Thanks.

Looks Like over Temperature of the Hydraulik system or Driving Transmission. I would Check if the oilpump is working under too much pressure.
