The Process of Changing the Blade of a Table Saw

Remove the Plate of the Blade
Place the blade plate on the table saw. The bed plate, as the name suggests, is a plate of metal that remains on the upper surface of the table saw. Generally, most of the blade plates are secured with two screws, one front, and another back screw. You can loosen or remove the screws to remove the plate. Once removed, place the plate aside out of the way.
Remove the Blade
Now, move the plate around until it reaches the highest position. The blade may turn accidentally. To avoid this problem, arrange a small wood block and place it against the blade. Locate the nut and washer and then remove them from the blade. You can do it by turning the nut with a wrench in the anti-clockwise direction i.e. towards you. After removing the blade, set it aside out the way while working.
Install a New Blade
Put the blade onto the blade housing and make sure the teeth of the blade are positioned toward the front of the table saw. Locate the nut and washer, and fix the blade in place by tightening the nut turning a wrench in clockwise direction i.e. away from you. Use a small wooden block to hold the blade safely.
Re-install the Blade Plate
Now, you will utilize a screwdriver for reinstalling the blade plate though tightening the screws. It will secure the plate at the top of the table saw.
Turn the Power On

- Lower the saw blade below the table once your task is finished.
- A perimeter of two feet should be kept free around the saw to avoid sawdust and debris.
