How can we better repair and maintain vehicle? There are six points that require attention, and I will present them to you today.
1. Avoid mechanical damage.
When performing maintenance operations, clear operating signs must be installed to prevent injury to others as a result of improper operation. When starting vehicle, pay attention to gear position of transmission to prevent accidental movement of vehicle and injury to people. When working under hood, other people should be allowed to leave cab to avoid accidental injury caused by sudden engine rotation or operation of someone else's control mechanism. If it is necessary to work under vehicle, obvious signs should be installed and vehicle should be covered with a car cover. When using jack to support vehicle, jack must be stable. Before driving, you must prepare driving tools, and it is forbidden to use fragile items such as bricks. When installing assembly, do not manually check screw holes, keyholes, etc. to avoid breaking your fingers. When testing engine, do not work under vehicle.
2. Avoid fire.
When servicing your vehicle, you often need to use flammable and explosive items such as oil and cleaning products. When doing this, remember to use fire fighting measures and have a fire extinguisher ready just in case. Do not smoke near fuel tank and battery, as combustible gas from fuel tank and hydrogen from battery are highly flammable.
3. Avoid burns.
A freshly switched off engine must be handled with care to avoid burns due to relatively high temperature of engine components (water tank, exhaust pipe, power steering fluid tank, spark plug, etc.). If engine temperature is high, never remove water tank cap or release water supply switch to avoid burns.
4. Avoid car damage.
Brake fluid is corrosive to vehicle paintwork and can dissolve paintwork quickly.
5. Avoid inadvertent attention to rotating parts and vehicle protection during road testing.
Keep hands, clothing, and tools away from rotating fan and fan drive belt while engine is running. During test run, condition of every part of vehicle must ensure safe parking and efficient steering. Road test vehicles must have obvious test marks. During test run, personnel must drive safely and test on a dedicated test track.
6. Do not pay attention to cleaning of workplace.
When closing engine cover or other assembly covers, you should check for tools, rags, removed parts and other items, and you can close them after making sure they are correct
