A water pump, a pair of car maintenance related to all aspects, in the maintenance operation, should set a clear work mark to prevent other people from being mistakenly injured. Here are some of the things you need to pay attention to when car maintenance, so that you can be safer when car maintenance.
1. Avoid mechanical damage.
There are various aspects related to the maintenance of the car. When performing maintenance operations, an obvious work mark should be set to prevent other people from being injured by mistakes. When starting the car, pay attention to the gear position of the transmission to prevent the car from being mistaken and injuring people. When working under the hood, allow others to leave the cab to prevent sudden engine rotation or other people’s manipulation of the mechanism, resulting in accidental injury. If you need to work under the car, you should set a clear sign and cover the car with a wooden cover. When using a jack, the jack should be placed smoothly. Drivers (driving stools) should be prepared before driving, and fragile objects such as bricks are prohibited. When installing the assembly, do not manually test the screw holes, keyholes, etc. to avoid breaking the fingers. When testing the engine, do not work under the car.
2, avoid fire.
When car maintenance, you often need to use flammable and explosive materials such as oil and cleaning agents. Don’t forget the fire-fighting measures at this time, prepare fire extinguishers, just in case. Do not smoke near the fuel tank and battery, because the combustible gas that escapes from the fuel tank and the hydrogen that escapes from the battery are easily ignited.
3, avoid burns.
Engines that have just been turned off have higher temperatures due to the various components of the engine (water tank, exhaust duct, power steering tank, spark plug, etc.) and must be carefully contacted to prevent burns. If the engine temperature is high, never remove the tank lid or loose open water switch to prevent burns.
4, avoid damage to the car.
Brake fluid has a detrimental effect on the paint film of the car (including the paint film of the shoes), which dissolves the paint film quickly. Brake fluid is harmful to the eyes and should be rinsed off immediately with water if splashed into the eyes.
5, avoid paying attention to the rotation of the machine and the road test protection.
While the engine is running, be aware that hands, clothing, and tools must leave the rotating fan and fan drive belt (preferably remove the worn ring, watch, tie, etc.). During the test run, the condition of each part of the car should ensure that the safe parking and steering are effective. The road test car must have an obvious test sign. When commissioning, personnel must ride safely and carry out on a dedicated test driveway.
6, avoid paying attention to the cleanup of the workplace.
When closing the engine cover or other assembly cover, check that the tools, rags, and removed parts are forgotten and can be closed only after confirmation.
