1. Shaking your head and shaking your head: This phenomenon is more common in old machines. Because the clamp is not tightly fixed, the filter and the intake pipe or the connection between the intake pipe and the body are loose. When the engine is working, the air filter is shaken. Under long-term vibration, the air filter is easily deformed and damaged, and loses its filtering effect.
2. Wearing masks: Some machines are covered with gauze at the entrance of the air filter in order to increase the filtration performance of the air filter. After being covered with cloth, the intake resistance is increased, resulting in insufficient intake of air during engine operation.
3. Lack of maintenance, increased wear: the center tube is dirty; the three slings connected to the oil pan and the filter housing are damaged or partially damaged; no effective measures are taken; the seal ring, the pad is missing, misplaced or damaged; The crankcase ventilation pipe is detached; the oil in the oil pan is dirty or inorganic oil, and the oil is too much or too little, or the oil is wrong.
These three conditions often occur in the use of air filters. These three aspects are the most easily overlooked by the staff, so you should check whether the air filter is installed properly before use, and the gauze can be used. Do not use, regular maintenance and maintenance should be kept up, in order to extend the life of the air filter for better and more stable work.
