How to change the blade on a table saw?

To change the blade on a table saw, first unplug the saw for safety. Remove the blade guard and loosen the arbor nut holding the blade in place. Carefully remove the old blade and replace it with the new one, making sure the teeth are facing the right direction. Tighten the arbor nut securely and replace the blade guard. Plug the saw back in and test the new blade before use.
