The fan motor is out of oil and won't turn, how should I add oil and where? Please illustrate, or send me a picture to tell me which place is fine, thank you very much!

1, this is the front of the fan, this side first.

2, this is the back side, start from the back to remove.

3, remove the back of the non-stick paper.

4, after that you can see a round iron snap.?

5, and then use a flat screwdriver to pry out the buckle, be careful not to be too hard to the buckle popped off, the following is to remove the buckle look.?

6, and then turn to the front to remove the fan body. The following is the removed fan blade body, there are some dust, you can properly clean off.

7, below the fan body is the motor, the main part that prompts the fan to turn.

8, the back of the fan housing body. Smear some lubricant on top of the rollers on the center shaft.
