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. As long as we understand the meaning of these error codes, we can easily resolve these faults ourselves. Compared to looking for a maintenance master to help us check, we understand the code has been greatly shortened our time and economic costs.

Therefore, understanding the meaning of the error code plays a very important role in solving the problem of malfunction in the operation or maintenance of the excavator. In this article we will introduce the following models from SK-6E, SK200-2 / -3, SK200-6, SK210-8, SK330-6E, as follows:
