• Thin oxygen in high altitude areas
3. Troubleshooting flow diagram
| step | Testing items | Normal parameters |
|---|---|---|
| first step | Battery voltage detection | ≥24V (large excavator) |
| Step 2 | Fuel pump pressure test | 0.2-0.3MPa |
| Step 3 | Cylinder compression detection | ＞2.5MPa |
4. References to recent hot cases
•Inner Mongolia construction site case(August 15): Colloidal deposition of the fuel system due to the use of inferior diesel, clean the fuel tank and replace the filter element.
•Popular Douyin videos(3.2 million views): Displays the temporary solution to the battery power loss problem through the "leap-on startup method".
V. Preventive suggestions
1. Recommended periods of regular maintenance:
| Battery detection | Every 250 hours |
| Fuel filter replacement | Every 500 hours |
| Circuit system inspection | Every 1000 hours |
2. Special precautions in winter:
• Use -35# diesel (Northeast)
• Install the preheating device
• Water accumulation in the oil circuit after shutdown
