A large amount of gas will enter the engine of excavator when the excavator is working. It’s as significant as the breathing for human. If the dust and impurity enter the engine system, the consequence is unthinkable. Therefore, the effect of air filter is particularly important.

It’s astonishing that the driver in video unassembled the filter and blew off the dust by the gas from exhaust pipe. Such operation will not only damage the filter by hot exhaust gas, but also plug up the filtration pore in filter. Moreover, the dust may enter the machine through air inlet and damage the machine.

Please replace the air filter timely and correctly.
