When it comes to maintaining your new 6 tons excavator, it is crucial to adhere to a regular maintenance schedule to ensure optimal performance and longevity. 

As a general guideline, it is recommended to conduct maintenance after approximately 50 working hours. 

During this initial maintenance, it is essential to replace all the filters in your excavator, including the engine oil filter, hydraulic oil filter, diesel oil filter, and air filter. 

By replacing these filters, you can effectively remove any contaminants and ensure that your excavator operates at its best capacity.

The engine oil filter plays a vital role in keeping the engine clean and free from debris. 

By replacing the engine oil filter regularly, you can prevent any potential damage to the engine and maintain its efficiency. 

Similarly, the hydraulic oil filter is responsible for filtering out impurities from the hydraulic system, ensuring smooth and reliable operation. 

By replacing this filter, you can prevent any potential damage to the hydraulic components and maintain optimal performance.

The diesel oil filter is another crucial component that should be replaced during maintenance. 

This filter helps remove any impurities or contaminants from the diesel fuel, ensuring that only clean fuel reaches the engine. 

By replacing the diesel oil filter, you can prevent any potential clogging or damage to the fuel system, allowing your excavator to operate efficiently.

Lastly, the air filter is responsible for filtering out dust, dirt, and other particles from the air intake, ensuring clean air reaches the engine for combustion. 

By replacing the air filter regularly, you can prevent any potential damage to the engine caused by contaminated air and maintain its performance.

In conclusion, conducting regular maintenance on your new excavator is essential for its optimal performance and longevity. 

By following the recommended maintenance schedule and replacing all the necessary filters, including the engine oil filter, hydraulic oil filter, diesel oil filter, and air filter, 

you can ensure that your excavator operates at its best capacity and remains in excellent condition for years to come.
