In daily operations of the excavator, due to wear and tear, poor working environment, untimely maintenance, improper operation, etc., various problems and faults will occur. It is displayed on the display screen of the excavator and reminds the operator which part of the excavator is faulty.

At first, these faults are small problems, but continued use will cause major mechanical accidents and may endanger the life of the operator. Therefore, if the driver knows the meaning of the fault represented by these fault codes and solves the machine failure in time, the accident can be prevented.
