1 Dou Shan DH370LC-9 excavator engine maintenance
The oil and oil filter core must be used in the positive factory, and the maintenance cycle is replaced. The old machine should be carefully protected. The oil filter change time can be shortened to make the engine life longer.
Diesel oil is provided by regular gas stations. Even if the diesel oil is added to the regular gas station, do not directly join the tank and filter it before it is added (more commonly used in refueling hosiery).
The air filter core is often checked, the outer filter ash is much more compressed air from the inside out, the air pressure can not be too large to prevent the filter core from blowing. The inner filter can not be cleaned. The external filter is cleaned for 2 or 3 times and the internal filter is replaced at the same time.
Do not use idle work for a long time to save fuel and prevent carbon deposition.
Before discharging every day, drain water at the bottom of the diesel tank and at the oil-water separator. The diesel filter cartridge will buy the factory parts and replace the diesel filter element according to the specified maintenance period.
Supplement: the filter paper of the factory is fine and the amount of impurity interception is large. Therefore, it is easier to clog up. The replacement period of the filter element is shorter than that of the auxiliary plant.
Hydraulic maintenance of 2 Dou Shan DH370LC-9 excavator
According to the specified maintenance cycle, replace the hydraulic oil, oil return filter element and pilot filter element, and pay attention to whether there are any iron scraps or copper scraps on the filter core.
