The process of cleaning the air filter:
1. First open the box containing the air filter, there are four clips around it, pull it up to open it;
2. Open the cover of the air filter and see the white air filter element inside. You may think that this is a new filter element, but it is not entirely true. This is actually the back of the filter element, and the air intake enters from the bottom, so this side is very clean;
3. Then take out the air filter. Before cleaning the air filter, use high-pressure oxygen to blow off the floating soil on the surface, so as to avoid the intervention of more dust when opening the air inlet. After evacuating the air filter, the air inlet will actually be very dirty, so you can wipe it clean with a clean cloth.

3. After opening the cover, take out the air filter element, and pay attention to the direction in which the filter element is placed when taking it out;
4. Check and clean the filter element. If the surface of the filter element is damaged or too dirty, it is recommended to replace it;
