1. Check whether the working lights and indicator lights of the excavator loader are damaged, and whether the electrical, gas, and oil circuits and pipelines are aged or damaged.

2. Check if the dust in the air filter of the excavator loader engine affects the intake effect.

3. Check if the connecting bolts of the front and rear transmission shafts are loose or detached, with a locking force of 530N M.

4. Check if the connecting bolts of each pin shaft are loose.

5. Check if the tires are damaged and if the inflation is sufficient (front wheel: 0.30-0.32 MPa, rear wheel: 0.28-0.30 MPa). The tire pressure of the excavator loader must be controlled within the specified range. Is the tire bolt loose with a locking force of 830N M.

6. Check for oil, water, electricity, or air leaks.

7. Check the water level, transmission oil level, hydraulic oil level, and brake oil level.

8. Add grease to each nozzle.

9. Check the wear of the brake pads.

10. Check the wear of the bucket blade and teeth. When the blade is worn by 10cm and the wear of the teeth exceeds 1/4 of the total length, it needs to be repaired or replaced.

11. When disassembling and installing the excavator loader battery, the positive and negative poles should be distinguished, and the nut should be securely tightened. The negative pole (ground terminal) should be first disconnected during disassembly. At the same time, avoid accidental contact between metal objects and battery terminals, causing short circuits.

12. When the mining excavator loader has just stopped working, the engine coolant, oil in all parts, exhaust pipes, and mufflers are all at high temperatures. If the cover is removed or the oil is drained or the oil filter is replaced, it can cause burns or other injuries. It is recommended to wait for the temperature to drop before maintenance and inspection.
