Before the start of the spring, the machine keepers need to know the excavator maintenance essential

After the excavator has been shut down for a long time in winter, some oil and materials may change. In order to ensure that the equipment for restarting construction can achieve the best use condition, the machine friends must remember to do detailed equipment inspection before starting construction. .

Check before starting

1. Check the fuel level of the excavator spare parts and treat the fuel tank for sewage discharge.

2. Check the oil level of the excavator and the oil quality of the engine oil.

3. Check the hydraulic oil level, hose and hydraulic oil quality of the excavator.

4. Check the gear oil level and oil quality of the slewing reducer of the excavator.

5. Check the oil level and oil quality of the travel gearbox of the excavator.

6. Check the cooling liquid level and check whether the water pipes are cracked or seepage.

7. Check if the slewing mechanism bearing butter is enough.

8. Check if the large ring gear butter is enough.

9. Add butter to each pin and lubrication point and squeeze the old oil out of the oil passage if necessary.

10. Check that the engine mat is intact.

11. Check the fan belt and engine belt tension to see if it is aging.

12. Check the tension of the track.

1. When the ambient temperature is lower than 3 °C, turn on the preheat switch before starting the machine to preheat.

2. Remove the turbocharger inlet pipe before starting the machine, add appropriate amount of oil to ensure the lubrication of the turbine shaft.

3. Start the equipment, the engine runs at idle speed for 5-10 minutes, the hydraulic pressure is up to 40 °C without load operation, and all hydraulic functions are cycled several times before construction.

4. If the equipment is not used for a long time, the thin oil layer on the sliding surface may be damaged. It is necessary to cycle and turn the hydraulic function 2-3 times to lubricate the sliding surface.

5. In the freezing weather, turn the upper frame to the 90 degree position before walking, hold up the track, and idling a few turns before and after, and remove the dirt impurities around the carrier roller, the roller and the guide wheel.

6. Drain and discharge the oil-water separator. https://jnjmzm.wixsite.com/sdjygcjx
