The engine in the process of work to absorb a lot of air, if the air is not filtered, the dust suspended in the air is inhaled into the cylinder, it will accelerate the piston group and cylinder wear. Larger particles entering between the piston and cylinder will cause serious "cylinder pulling" phenomenon, which is particularly serious in dry and sandy working environment. The air filter is installed in the front of the carburetor or the intake pipe, to filter the dust and sand in the air, to ensure that the cylinder into the sufficient amount of clean air, according to the principle of filtration, air filter can be divided into filter type, centrifugal type, oil bath type, compound type
In maintenance, the paper filter element must not be put in the oil cleaning, otherwise the paper filter element will fail, but also easy to cause flying accidents. Maintenance, can only use vibration method, soft brush division (along with its wrinkled brush) or compressed air back blowing method to remove dust and dirt attached to the surface of the paper filter element. For the coarse filter part, dust should be removed from the dust collecting part, blade and cyclone pipe in time. Even if each time can be carefully maintained, the paper filter element can not completely restore the original performance, its intake resistance will increase, therefore, generally when the paper filter element needs to be maintained for the fourth time, it should be replaced with a new filter element. If the paper filter element is cracked, perforated or the filter paper and the end cover are degummed, it should be replaced immediately.
