In fact, the daily maintenance work is very simple, summed up is: clean, tighten, check, supplement.
　　A, clean
　　The air contains a lot of dust, sediment and acidic substances, not only easy to be leakage of oil adhesion, easy to form a hard insulation layer under high temperature baking, so that the heat dissipation performance of the parts become poor, and easy to be electrostatic body suction and erosion paint surface, so that it fades prematurely.
　　1. Clean air filter
　　Too dirty air filter will sharply block fresh air into the cylinder, resulting in gas concentration, incomplete combustion, power reduction, excessive exhaust. Modern air filters generally use paper filter elements, cleaning attention: do not use water or oil wash, should be used to pat and blow cleaning method. Dab method namely dab filter element end face gently, make dust falls off. Blow-cleaning method is to use compressed air filter core inside to blow out cleaning, air pressure: force should not exceed 0.3n /Pa
　　2. Clean the oil filter
　　Oil filter clippers become blocked, which can block the flow of lubricating oil and cause the engine to become poorly lubricated, become more worn, or burn shingles, etc. For this purpose, regular cleaning or replacement should be carried out. Usually every 8000km to change, if the climate is dry. It should be shortened to 5,000 km and replaced once.
　　3, clean the battery
　　Modern cars are generally used without maintenance battery, the first clean battery top, avoid the pole column due to electrolyte or other impurities and cause a short circuit; Second, clean the battery terminal post, to prevent the joint oxide and lead to poor contact. Vent hole should be smooth, so as to avoid the battery pressure or temperature is too high and the hand burst.
　　Second, the fastening
　　After cleaning the vehicle, tighten the joints. Due to the vibration, jolting, rocking and other reasons in the running process of the vehicle, the connecting parts are bound to become loose and worn. Therefore, in the daily maintenance to timely fastening. The daily fastening of connectors is directly related to traffic safety, especially important parts steering, braking, transmission, etc., must not be taken lightly.
　　1. Firstly, tighten the joints of various rubber pipes around the engine to prevent oil leakage.
　　2. Secondly, tighten the connectors of all lines and electrical equipment to prevent circuit break, short circuit and iron lap from affecting the normal operation of electrical equipment.
　　3. Once again, check and tighten the main connectors. Such as the generator belt, steering motor brake joint, transmission system and tires and so on.
