Flip the router upside down or place it on its side so you can see the spindle lock.
Remove the cullet wrench from the base plate of the router by pulling it out. The wrench is black and flat.
Place the wrench onto the cullet and press in the silver spindle lock. The cullet is black and looks like a hex nut. It is the part of the router that clamps to the router shank. The spindle lock is a sliver pin that you press into a hole located on the side of the spindle.
Loosen the cullet with the wrench by turning the wrench counterclockwise. With the cullet loosened, pull the router bit out of the cullet.
