What does it mean to shake your head with a circular fan?

1. First of all, the fan will shake left and right when working. This kind of shaking is splayed because the bracket or bearing of the fan is damaged or improperly installed.

2. Then check whether the bracket and bearing of the fan are damaged, replaced or repaired in time to ensure the smooth operation of the fan and prolong its service life.

3. Finally, buy a fan and choose products with better bracket and bearing quality to reduce the possibility of this problem.
