Matters needing attention in using electric fan
1. Read the instructions carefully before use, and fully grasp the structure, performance, installation, use and maintenance methods and precautions of the electric fan.
2. After the electric fan is used for a long time, it is easy to get dust on the bottom of the fan blade. This is because the friction between the running fan blades and the air makes the fan blades generate static electricity, which is easy to attract fine dust floating indoors. Clean the electric fan of oil or dust in time, and clean it with neutral detergent and soft cloth, so as not to damage the shell surface or coating. When disassembling and assembling the fan blades, pay attention to protecting the fan blades, so as not to deform the fan blades, so as to avoid vibration or shaking when the fan is running.
3. If the electric fan is hot, abnormally burnt and slow in use, it shall not be used any more, and the power supply shall be cut off in time for maintenance.
4. When using an electric fan in summer, it is forbidden to blow for too long after rapid heating and the wind force is too large. It's best to shake your head, slow down, and naturally keep out the wind, but it's better to sleep in the wind.
5. Families with children should pay special attention to the use safety of electric fans, put electric fans in places where children are not easy to touch, and educate children not to touch blades out of curiosity to prevent accidents.
