How do you change the router bit?

To change a router bit, first, ensure the router is unplugged for safety. Use the wrench that came with your router to loosen the collet nut by turning it counterclockwise. Remove the old bit, insert the new one into the collet, and tighten the collet nut securely by turning it clockwise. Finally, plug the router back in and perform a test run to ensure the bit is properly installed.
