Kobelco excavator fault codes list

Service technicians have no problem recognising breakdowns and carrying out machine diagnostics, Kobelco excavator fault codes list, plus they are familiar with equipment from a variety of manufacturers.

As an excavator driver, it is inevitable to encounter an excavator running fault. Many errors are small, which will prompt for some error codes on the display. Therefore, understanding the meaning of the error code plays a very important role in solving the problem of malfunction in the operation of the excavator or maintenance. We will introduce the following models from Kobelco SK-6E, Kobelco SK200-2 / -3, Kobelco SK200-6, Kobelco SK210-8, Kobelco SK330-6E, as follows:
