This step is easier with help. You will need two hands to unscrew the bolt and turn the fan simultaneously.

Gently apply the pliers around the bolt in the middle of the fan blade and keep it there while you place your other hand onto the fan blade itself.

Simultaneously hold the pliers in place to keep the bolt from spinning and turn the fan blade counterclockwise with force, as seen in the first picture.

Turning the fan blade may require substantial force; be careful while removing due to a sudden jolt when loose.

The bolt should become loose allowing you to remove the fan blade from its place, as seen in picture 2.
