Excavators are strong soldiers on construction sites and municipalities. Those high-intensity operations are just daily work for them, but everyone knows that the working environment of excavators is very harsh, and it is common for dust and mud to fly all over the sky.

Have you maintained the excavator's lung air filter properly? The air filter is the first level of air entering the engine. It will filter out the dust and impurities in the air to ensure the healthy operation of the engine. Next, I will teach you what to pay attention to when replacing and cleaning the air filter!

Excavator air filter cleaning

Notes on cleaning the air filter:

 1. When cleaning the air filter element, be sure not to use tools to disassemble the shell or filter element of the air filter element, otherwise the filter element will be damaged easily and the filter element will fail.

2. When cleaning the filter element, do not use tapping and tapping to remove dust, and do not leave the air filter element open for a long time.

3. After cleaning the air filter element, it is also necessary to confirm whether the sealing ring of the filter element and the filter element itself are damaged. If there is any damage, it should be replaced immediately, and do not continue to use it with luck.

4. After cleaning the air filter element, a flashlight should also be used for irradiation inspection. When a weak part on the filter element is found, it should be replaced in time. The price of the filter element is a drop in the bucket for the engine.

Precautions when replacing the air filter element of the excavator:

After the air filter has been cleaned 6 times in a row or damaged, it needs to be replaced. The following 4 points must be paid attention to when replacing.

1. When replacing the outer filter element, replace the inner filter element at the same time.

2. Don't be greedy for cheapness, use filter elements with prices lower than the market price, and be careful to buy fake and shoddy products, which will cause dust and impurities to enter the engine.

 3. When replacing the filter element, it is also necessary to check whether the sealing ring on the new filter element has dust and oil stains, and it should be wiped clean to ensure the tightness.

When inserting the filter element, it is found that the rubber at the end is expanded, or the filter element is not aligned, do not use brute force to install it, there is a risk of damaging the filter element.
