Error codes of excavators often appear in the process of use. Usually, when the excavator has problems, the display screen of the excavator will appear error code. Most excavator users are zero-based on error codes. Therefore, when encountering error codes, they will be confused or need to find a professional repairman to repair.

If you have some knowledge of common error codes, you can immediately troubleshoot the excavator. In this way, you can save much time and cost. This article will introduce several common error codes of Hitachi ZX240-3 excavators, as well as the second and the third generation Hitachi excavators.
