Hitachi Zaxis Error code

Author:Rose Date:2019-10-14

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 find a professional repairman to repair. Although you have to find a professional maintenance technician or repair factory to repair, they also need to spend a lot of time to detect the error code. If you have some knowledge of common error codes, you can immediately troubleshoot the excavator. In this way, you can save time and cost. So it is important for you to understand the meaning of these error codes. This paper will introduce several common error codes of Hitachi ZX240-3 excavator, Hitachi excavator-2, -3 series of error codes, etc.
