Daily Maintenance

1.Lubrication System

· Regularly check all lubrication points to ensure they receive adequate lubrication oil. The quality and quantity of lubrication oil directly affect the operational efficiency of the equipment.

· Before and after daily operations, check the hydraulic oil level and replenish as necessary.

 

2.Filters

· Regularly replace the air filter to ensure the engine receives clean air, preventing performance degradation.

· Check the oil filter, and it is recommended to replace it every 250 hours to keep the oil circuit unobstructed.

 

3.Hydraulic System

· Weekly check the hydraulic oil level and quality to ensure there is no contamination. Regularly replace hydraulic oil to prevent deterioration.

· Inspect all hydraulic hoses for leaks and ensure connections are secure.

 

 

Seasonal Maintenance

1.Winter Maintenance

· Check the antifreeze concentration to ensure it can operate normally in low temperatures. Add antifreeze as needed to prevent engine freezing.

· Inspect battery performance, as cold weather can affect battery power.

 

2.Summer Maintenance

· Regularly clean the cooling system to ensure the radiator is free of debris, preventing engine overheating.

· Monitor the temperature of hydraulic oil to avoid high temperatures causing oil degradation.

 

 

Common Issues and Solutions

1.Difficulties Starting the Excavator

· First, check the battery level and ensure connections are secure.

· Inspect the fuel system to ensure there is enough fuel in the tank.

 

2.Hydraulic System Failure

· If the hydraulic system is sluggish, check the hydraulic oil level and add oil if necessary.

 

Regular maintenance and care not only extend the lifespan of mini diesel excavators but also enhance their working efficiency and reduce the likelihood of failures. Users should establish a detailed maintenance plan and conduct regular inspections to ensure the equipment operates at its best.
