(1) The filter element uses microporous filter paper and the surface is treated. When the engine is running, the air filters dust through the micropores to ensure that clean air enters the cylinder. In use, a layer of dust will stick around the filter element. When cleaning, do not use water or oil to prevent oil from entering the filter element. There are two common cleaning methods: 1. Tapping method, remove the filter element from the housing, tap the end surface of the filter paper lightly to make the dust fall off. Do not touch the outer surface of the filter element to avoid damage to the filter element. 2. Blowing method, that is, use compressed air to blow the air in the filter element to blow off the dust. To prevent damage to the filter paper, the compressed air pressure should not exceed 0.2 to 0.3 MPa.
(2) Clean and replace the filter regularly
In use, the air filter element should be cleaned regularly in accordance with vehicle maintenance regulations to avoid increasing intake resistance, reducing engine power, and increasing fuel consumption due to excessive dust adhesion on the filter element. If the filter element is damaged, it should be replaced in time.
(3) Install correctly to prevent air from entering the cylinder without filtering
(4) When inspecting the air filter, the gasket on the filter element must be firmly installed. If the gasket is damaged or damaged, replace it with a new one.
Small excavators should be used and maintained well, so as to perfectly provide convenience for our lives.
