1.the air filter is too dirty will steeply hinder fresh air into the cylinder, resulting in too thick gas, incomplete combustion, power reduction, exhaust exceeding the standard. Modern air filters generally use paper filter element, cleaning attention: do not use water or oil wash, should use the pat method and blow washing method. Patting method is to gently pat the end face of the filter element to make the dust fall off. The blowing method is to blow the compressed air filter element from inside to outside. The air pressure: force should not exceed 0.3N/Pa.

2.oil filter machine blocked, will hinder the flow of lubricating oil, make the engine poor lubrication, increased wear and even burned tile. For this reason, it should be cleaned or replaced regularly. Usually change once every 8000km, if the weather is dry. It should be shortened to 5,000 km and replaced once.

3.modern cars generally use maintenance-free battery, first clean the top of the battery, to avoid short circuit caused by electrolyte or other impurities between the poles; Secondly, clean the battery terminals to prevent the joints from producing oxides and resulting in poor contact. The air vent should be unblocked, so as not to burst the hand due to high pressure or temperature in the battery.

4. avoid using the mouth suction tubing. Gasoline is not only flammable and explosive, but also poisonous. Leaded gasoline, in particular, can damage the nervous system, digestive tract and kidneys. In addition, gasoline also contains a high concentration of sulfide, because hydrogen sulfide also has a certain toxicity, if inhaled gasoline stomach, will lead to poisoning or death. In case of inhalation, force yourself to vomit and seek medical treatment in time.

5. avoid stained carburetor cleaning agent. Most carburetor cleaners contain methyl chloride, aromatic compounds, and ethanol, all of which are somewhat toxic and therefore dangerous to inhale or splash on your skin or eyes.

6. do not pay attention to the cleaning of the workplace. When closing the engine cover or other assembly cover, check whether tools, rags and removed parts and other items are forgotten. Only after confirming that they are correct, can they be closed.

7. Avoid running the engine for a long time in an unventilated garage. Engine exhaust contains carbon monoxide, an invisible and invisible gas. Prolonged exposure to low levels of carbon monoxide can cause headaches, shortness of breath, nausea, dizziness, mental confusion and even brain damage. If you start the engine in the garage, you should open the garage door or open the exhaust device so that the exhaust gas can be discharged from the garage at any time. Do not stay near a working engine exhaust pipe for long periods of time, even if working in the open air.
