Get access to the blade

The first step whenever we’re working with power tools is to make sure it’s unplugged. Then remove the throat plate and the blade guard to get access to the blade. This is a little different with each sauce, so check your table saw’s owner’s manual if you’re not sure how to do this. raise the blade to its highest point to get good access.

Loosen the arbor nut

With the garden throw plate removed, you can see the blade which is mounted on this shaft which is called the Arbor and it’s secured with the arbor nut and washer. You can follow multiple ways to loosen that arbor nut.

Method 1

Now you’re going to need a wrench. Most table saws come with a set of wrenches. If for some reason you no longer have these wrenches, you can use an adjustable wrench or an open-ended wrench. Take two wrenches and use one to hold and secure the arbor and loosen the arbor using the other one.

Method 2

The next method is more common on smaller and portable table saws. Some compact table saw feature an arbor lock. It’s a small lever located near the arbor that locks the arbor in position. Activate this function and loosen the nut with a wrench.

Method 3

The third method of loosening the arbor knot is to use an accessory like a benchtop blade lock. What this does is holds the blade in place so you can then loosen the nut with a wrench keeping your hands safe

Method 4

One final method is to use a wrench and a block of wood. You simply wedge the block of wood up against the blade that secures it from spinning and then loosen the nut with a wrench. Sort of a clever variation of this is to lower the blade down so the teeth are just above the tabletop height. Place the wrench on and let it rest on the reverse of the opening. Then you simply bomb the block of wood against the blade and it frees them up.

Remove the nuts

Now, with the nut-free, simply loosen it with your fingers. Put your index finger at the end of the arbor so that as the nut releases from the arbor, your finger holds it. This way, you can prevent the nut from falling into the base of the table. After releasing the nut completely, remove the washer.

Replace a new blade

Take off the old blade. Install the new blade, making sure that the teeth are facing towards you instead of away from you. And then replace the washer and the nut, and then you’re simply going to tighten the nut using the same method that you use to loosen the nut, just in reverse.

Reassemble the table saw

After installing the new blade, replace the guard system. Reinstall the throat plate and you are ready to get back to work. Choosing the right blade for the application and making sure it’s a sharp blade are two of the keys to having great results.
