Caution:
1) The fan is rather long, and therefore use one hand to hold the bottom of the fan while the other hand
holds the handle attached to the front of the fan and pull it out slowly.
2) When you pull out the fan, the fan is powered off. However, it may still rotate for a while for the sake of
inertia. Be careful and do not put your finger into the rotating fan.
