1. After a new machine or major repair, the diesel engine cannot be fully loaded from the beginning and cannot run at high speed. Before switching to normal operation, it should operate at low speed and light load for 50 hours.
2. Ensure that the fuel is clean. If necessary, filter through sediment or silk.
3. Maintain normal water temperature (70-85 ° C) and hydraulic pressure (medium speed 0.2-0.4 MPa).
4. Discovered abnormal conditions while driving and immediately inspected the vehicle.
5. To prevent scaling and shorten engine life, it is recommended not to use "hard water" as cooling water.
