What should I pay attention to when repairing a car?

Precautions for automobile maintenance 1. Avoid mechanical injury.

Many people always focus on what they are doing, but ignore the people around them, or get hurt accidentally. Therefore, when carrying out maintenance operations, obvious operation signs should be set to prevent others from being hurt by misoperation.

Among them, the following situations need more attention:

1. When working under the hood, others should be allowed to leave the cab to prevent the engine from suddenly turning or others operating the mechanism, causing accidental injuries.

2. If you need to work under the car, you should set clear signs and cover the car with a car cover. When a car is supported by a jack, the jack should be placed stably.

3. When installing components, do not test screw holes, lock holes, etc. Avoid breaking your fingers with your hands. Don't get out of the car while testing the engine.

Pay attention to car maintenance. Avoid fire.

When maintaining cars, it is often necessary to use flammable and explosive materials such as oil and cleaning agents. Don't forget the fire-fighting measures at this time, and prepare a fire extinguisher just in case. Pay special attention to avoid smoking near flammable and explosive materials such as fuel tanks and batteries to avoid explosion.

Note: Check regularly whether the fire extinguisher on the car is out of date. Once it is found out of date, replace it with a new one immediately, so as to put out the fire in the first time, control the fire and reduce the loss.

Pay attention to car maintenance. 3. avoid burns.

The engine that has just turned off must be handled carefully to prevent burns caused by relatively high temperatures in various parts of the engine (water tank, exhaust pipe, power steering fluid tank, spark plug, etc.). ).

Tips: If the engine temperature is high, do not remove the water tank cover or loosen the drain switch to prevent burns.

Pay attention to car maintenance. Avoid paying attention to the protection of rotating parts and automobile road test.

When the engine is running, be sure to keep your hands, clothes and tools away from the rotating fan and fan drive belt (it is best to take off the ring, watch, tie and other items) to avoid these items being involved.

During the test run, the conditions of all parts of the car should ensure safe parking and effective steering. In addition, it should be noted that the car for road test must have obvious test marks. During the test run, personnel must ride safely on the special test run track to ensure safety.

In addition to the four points mentioned above, it should also be noted that when maintaining a car, you need to know how to avoid some injuries caused by using liquids. For example, brake fluid is harmful to the paint film of automobiles (including the paint film of leather shoes). It can dissolve the paint film quickly, so be careful when using it. In addition, brake fluid is harmful to eyes. If it spills into eyes, it must be washed with clear water immediately.
