The emergence of bulldozers helped us solve the problem of digging earth and rocks. However, due to the changing seasons, the bulldozers will not be used for a period of time. However, in order not to affect the next use, it is necessary to maintain the parts of Shandong bulldozers regularly. Do you know how to maintain the unused parts of the bulldozer?

1. Preparation before parking.


Clean all parts of the bulldozer attachment, then place the complete machine in a dry room, not outside. If necessary, if it is placed outdoors, you should choose a flat ground and lay wooden boards. After parking, you should cover it with a drape. Perform maintenance work such as oiling, greasing and changing oil. The exposed parts of the piston rod of the hydraulic cylinder and the adjustment rod of the guide wheel should be covered with butter. For the battery, remove the "negative pole" and cover the battery, or remove it from the car and keep it separately. If the cold water is not discharged when the temperature is below 0°C, antifreeze should be added to the cooling water.


2. Storage during parking.


During the parking period, start the excavator once a month and drive for a short distance to build a new oil film on the lubricating parts of each part to prevent parts from rusting. When operating the working device, remove the grease applied to the piston rod of the hydraulic cylinder, and then apply the grease after the operation. To charge the battery, the excavator must be turned off while charging.


3. Pay attention after parking.


After a long-term shutdown, if the anti-rust operation is carried out at the end of each month during the shutdown, the bulldozer accessories should be handled as follows before use: open the oil pan and the oil drain plug of each box to drain the mixed water. Remove the cylinder head, fill the air valve and rocker arm with oil, understand the working status of the air valve, and adjust it if there is any abnormality. Put the excavator in a depressurized state without diesel injection, and turn the excavator with the starter; only in this way can the excavator start.
