Remove the clamps surrounding the protective cage by pulling each outward (away from the fan) one at a time.

Though this may require some force, don't pull on the clamps too hard, as they can be easily broken.

As you are removing the last few clamps, be sure to hold the cage with another hand. Otherwise, it will fall right off!

Once the front end of the cage is free, remove it from the fan and place it to the side for now.
