Many new and old drivers love to check their own vehicles, and even some owners like to do simple repairs and maintenance for their car without professional training. But it should be noted that if the operation is improper, it will cause danger. A case review: in November 19th, a truck driver in the Guangzhou Baiyun District Sha Tai Road climbed into the car and repaired the car at the bottom of the car. According to subsequent inspection, the driver did not pay attention to safety operation when he repaired the car. At that time, the driver made two fatal mistakes when he repaired the car: when he stopped the car on the downhill road, he didn't pull the handbrake when he repaired the car and repaired the car. So when the driver got off the car to inspect the car, his wheels were rolled up and his axle was turned up. The master suggested that some simple maintenance work can be handled by the owner, such as the replacement of the wiper, the body waxing, the interior cleaning, the body surface maintenance, the filling of glass water and so on. In addition to personal safety considerations, it is also for the sake of "health" of cars, and should be assisted by professional equipment during maintenance. When vehicle problems need to be repaired by themselves, what should we pay attention to? Avoid: there is no warning sign on the roadside maintenance vehicle. It is a very risky thing to repair cars on the roadside, and the traffic will be dangerous to you at any time. How to do it: when repairing vehicles on the roadside or waiting for rescue workers on the road, they must set up warning signs about 50 meters behind the train. If there is no warning sign on the vehicle, you can find some branches or obstacles from around to mark, so as to warn the rear vehicle's effect, so as to avoid traffic accidents. Avoid: a long time running engine in a ventilated garage. Avoid: when the car opens, the driver is open to the head of the engine cover: in the summer, the car is hot and the car is easy to open the pot. In the case of the car opening, the driver must not check it by himself, because in the case of opening the pot, open the engine cover, the high temperature of the water tank can easily cause the face or other parts of the body to be burned. What to do: if the engine is open, first stop the car on the side of the road, kill the fire, pull the key down, cover the machine, make it cool in the shade, and then call for the professional rescue workers to come. Avoid: oil pipe blockage nozzle suction pipe master tips: gasoline is not only inflammable and explosive, but also toxic. In particular, leaded gasoline can damage the nervous system, digestive tract and kidneys. In addition, gasoline contains high concentration of sulfide and hydrogen sulfide is also toxic. If the tubing is blocked, the owner of the car is very easy to suck up the gas in order to get through the tube. It can cause nausea and abdominal pain, and even lead to poisoning or death. How to do this: if the vehicle runs on the road, there will be a blockage of the tubing. Remember not to suck the oil pipe through the mouth, especially the leaded gasoline. In case of inhalation, you should be admitted to hospital in time after forcing yourself to vomit. If there is a problem of oil pipe blockage, it is best to call professional rescue personnel to help. Avoid: stop the bad car in the Banpo maintenance master hint: if the first case in the text, some car owners will stop the bad car directly in the half slope position repair, and forget to pull the hand brake, and finally cause serious accident. How to do it: when the owner stops, he should pay attention to whether the parking place is a slope. Check whether the car is still on the gear and pull the handbrake. If there is a slope, it is better to put obstacles under the wheel to prevent the vehicle from sliding suddenly. Avoid: the long run engine master in the non ventilated garage shows that many owners start the car in the closed space, ignoring the influence of the exhaust gas from the engine. Automobile exhaust is dangerous. It contains carbon monoxide. It is a kind of poisonous gas that can not be seen or smelt. It is easy to enter the cabin. If the owner is in a closed or poorly ventilated space for a long time, inhalation of low concentration of carbon monoxide can cause headache, shortness of breath, nausea and vomiting, dizziness of body and even brain damage. How to do this: never operate an engine in enclosed space. If the engine is started in the garage, the garage door should be opened or opened, so that the exhaust gas can be discharged from the garage at any time. Even outside, do not stay long near the working exhaust pipe.
