Failure case
Model: R210LC-3
Failure phenomenon: the part between the diesel tank and the engine catches fire and the wiring harness burns out
User opinion: If the wiring harness problem caused a fire, ask the excavator repair manufacturer to repair it
Inspection steps (analysis of the cause of failure):
1. The wiring harness in the excavator has been safely designed and there is almost no possibility of fire
2. Check that the fuses in the fuse box are intact and there is no line overload
3. Considering the winter time, the fuel may be frozen, which makes it difficult to start, and many people have
4. From the peripheral environment of the machine, the ground beneath the machine is covered with new soil, which may be judged to be human behavior
5. After turning over the new soil layer, many burned materials can be found, and the truth is finally revealed. The reason is that the user uses the burning method to defrost the fuel and burns the combustible materials to cause this failure.
Troubleshooting experience:
1. Investigating and understanding the real cause of the fault is more important than dealing with the fault itself
2. Appropriate reasoning from the associated conditions (which may be specific) helps to correctly determine the fault.
3. The user's statement can only be used as a reference, and must not become the basis for affecting our judgment of failure.
