The dry type air filter is made of paper element and sealing gasket, take care when in usage:

1. Check regularly and clean it rightly. When removing the dust on the paper element, it should use soft brush to clean the dust on the element surface along the welt seam and tap it down tightly. When doing the above operation, it should use clean cloth or rubber to block the two sides of the element, to compress the air engine or use pump to blow the air in order to blow the dust that attached on the element surface.

2. Do not use water or diesel, gasoline to clean paper element, or the filter hole will be blocked and then increase the air resistance, at the same time, the diesel will be easily blew to the cylinder and cause the aerodyne

3. When the element is broken or the upper and lower end is uneven, or the rubber sealing ring aging and deformation and damaged it should replace new parts

4. When installing, it should combine the gasket in different parts or ensure that the sealing ring cannot be installed omissivly or wrongly to avoid air short out. The element butterfly nut should not be twisted too tightly to avoid pressing the element broken.
