Komatsu 200-7 excavator is a popular model, so what are its advantages? Today, China's second-hand excavator market will analyze why this is the case. Friends who know a little about Komatsu 200-7 excavators know that the last batch of Komatsu 200-7 excavators was manufactured at the end of 2008. That is to say, even the last batch of Komatsu 200-7 excavators has been in use for several years. If it was manufactured before, the years are even longer. You know, under normal circumstances, the value of the excavator is very, very low after five years. But the Komatsu 200-7 excavator is an exception. So the Chinese second-hand excavator market tells you what the reason is? In fact, it is not that the Komatsu 200-7 excavator is so good. Of course, it is really good. It is because the new excavators Komatsu 200-8 and Komatsu 200-8EO are both electronic injection engines. The oil quality requirements are very high. If the oil is slightly inferior, the fuel injector will break. Therefore, it is easy to break and difficult to maintain. Therefore, there are so many excavator friends who still choose second-hand Komatsu 200-7 excavators. This is also the reason why Komatsu pc200-7 excavators have maintained……
