1. When conditions permit, please ask the car owner not to repair your car on the roadside. Repairing a car on the roadside is a high-risk thing. Repairing a car on the roadside will increase the risk factor when repairing the car.
2. Do not repair the car in an unventilated underground garage, because it is necessary to frequently adjust the car engine. In an unventilated place, the engine exhaust gas does not circulate, and the human body inhales too much exhaust gas, which can cause serious poisoning and cause death.
3. Do not repair the car on the ramp. If you forget to pull the handbrake, it will easily cause serious accidents when the car slips.
4. When you need to go to the bottom of the car to repair the car, it is best to have someone else help and look after it. An extra person is not only an extra helper, but also can help with the emergency situation, which can reduce the probability of accidents by the repairer .
5. After the car has just been driven, be careful not to open the hood to repair the cabin rashly. Because the temperature of the cabin of the car is very high at this time, it is easy to burn the skin. You must first wait for the engine to turn off, and then wait for the engine to dissipate heat and the temperature drops before performing maintenance.
