The electric fan motor is out of oil and can't run. How and where should I refuel? Please explain, or send me anywhere. Thank you very much.

1, this is the front of the fan, don't look here.

This side is the back, so we should start from the back.

3. Remove the non-stick paper from the back.

4. After that, you can see a round iron buckle. ?

5. Then lever out the buckle with a flat screwdriver. Be careful not to pull the belt buckle too tightly. Here's how to release the buckle. ?

6. Then turn to the front and remove the fan body. The following is the main body of the removed fan blade, with some dust, which can be cleaned properly.

7. Below the fan body is the motor, which is the main part to make the fan rotate.

8. Fan case on the back. Apply some lubricating oil to the rollers of the central shaft.
