I have an issue with my Kobelco SK-120 mark 5 excavator. The alarm is going off for everything in the machine. The screen indicates oil, water hydraulic etc. Is there a solution to this issue or does anyone know what to look at?
I would start by checking your grounding points.
you should take and upload a few pictures of machine's monitor, so we can see what error the device is reporting. That way we will be able to advise you more easily.
