Excavators how to care? 4, the cartridge enjoying. Filter acts as the oil or gas line filter impurities, prevents the formation of impurities invade fragmented external problems; use original cartridges; various filters to follow the (operating enjoying Manual) requirements current change, change the filter, it should be able to reflect on No metal attached to the old cartridge Hitachi Excavators 60, if there is metal particles, timely diagnosis and improvement measures. So careful of used excavators Hitachi Excavators offer maintenance, allowing the excavator in life, fewer problems, more benefits for you to win. See the commonly used digging machine errors, some maintenance personnel can not accurately determine the fault location, with "probably, almost" blind ideological dismantling of mechanical unloading large, the result is not only the original fault is not excluded, but the emergence of new problems. 1 Nissan Komatsu bulldozers, diesel power shortage occurs, the fault Hitachi Excavators, mechanical maintenance staff can not work disassemble the PT fuel pump and injectors did not find the cause of the fault, replace a fuel pump test, the fault persists. Finally, check the fault is due to the diesel internal impurities, caused by too much water, and this has led to the demolition PT fuel pump performance decreased, insufficient engine power. When mechanical failure, to be detected by the testing equipment to determine the most likely site of failure. In determining engineering mechanical failure, commonly used "exclusion" and "Comparative Law", in order from simple to complex, internal, the first order of assembly and then parts were Hitachi Excavators market after the first appearance, should not "do not ask indiscriminate, Big blind dismantling unloading. " Mistakes also a personal habit, as long as attention, according to the normal method of operation on it.
