1. First go to the hardware store to buy butter or other lubricants.

2. Remove the fan cover and set it aside.

3. Then remove the other side, press the fan blade and rotate it to the right to release it. Once removed, remove the fan blades.

4. After removing the fan blade and then removing the tools as shown in the picture, the left side will usually be loosely twisted. Once removed, the back cover will also be removed and placed.

5. Use a Phillips screwdriver to remove the rotating button and turn it to the left to release it. Remember not to deform it.

6. Then, remove the screwdriver in the picture, remove the motor cover after disassembly, and then pull down the front of the rear to remove it. To avoid trouble, please use a sharp tip Use pliers to remove it. Once removed, remove the front and rear guards.

7. Finally, remove the 4 screws of the motor, and then remove the motor cover.

8. Grasp the front cover, and then remove the back cover to remove it. Remember not to break the middle coil and remove it slowly.

9. Grasp the butter in the middle, and then move the butter one after another.

10. Reinstall the back cover and install the screws and tighten them.

11. After installing the motor screws, open the fan for lubrication. First lubricate from low speed to high speed. If it does not move, the capacitor has been burned. Remove the button cover to check the route. It can be removed and replaced. Use a capacitor.

12. Download and install the rotary button covers as shown in the picture, put them back to their original position, and then tighten the 3 screws to secure the screws.

13. Place the upper protective cover in the appropriate position by hand. After installing it, install 4 screwdrivers, and then tighten the back cover.

14. Then install the fan blade and turn it to the left to tighten.

15. The back cover is also placed in the same (external slot) slot and then tightened while manually pressing it into place.

Extended information:

1. The reason why it does not rotate is that the shaking head is blocked, which is caused by the deformation and bending of the connecting rod. At this time, there will be a source of sound, which can cause the deformed Remove the connecting rod and it can be ruled out after reshaping. It is the transmission failure that prevents the power from being transmitted. You can check the tooth rod swing head plate gear box clutch, etc. If you find any falling off or stuck foreign matter, or the inability to engage due to severe wear, etc. phenomenon, the lost parts should be eliminated or replaced.

2. Most electric fans use oil-containing bearings. This kind of bearing is usually a powder metallurgy product and is tightly packed in the oil hole inside the bearing. When the electric fan is working, the temperature of the motor rises, and there is a gap between the rotating shaft and the bearing. The friction and heat generated will gradually consume the lubricating oil, and the electric fan motor will not be able to maintain normal operation. The speed will decrease or even stop rotating, and the motor will burn out.

3. In the reduction box of the electric fan, the lubricating oil is usually replaced once every 3 to 4 years. When replacing, first remove the rear cover, remove the balance key, then remove the gear box cover, and use a small bamboo chip to Use a lightweight tool like this to gently scrape off the old grease inside, then wash it with clean gasoline, and then add an appropriate amount of new grease.
