Learn How to Change a Table Saw Blade

A table saw is an essential and handy machine to have at your disposal if you love doing DIY projects, or if you’re a woodworker or a constructor. With this machine, you’re able to make well-chiseled and accurate cuts at various angles in a fast and effective manner.

The machine consists of a circular blade that’s placed on an arbor. You secure the circular blade with a nut placed on top of a cup washer, and the blade protrudes through a table, enabling you to cut your materials with ease. Over time, as with any machine or tool, wear and tear take their toll, and you need to replace some parts with new ones. In this instance with a table saw, you’ll eventually need to replace the worn-out blade with a new and sharper one.

For someone who already knows how to change the blade on a table saw, the process is relatively straightforward. It should take you less than 6 minutes, provided you have the necessary tools and the expertise to get it done.

What you’ll need to change a blade is:

  • A screwdriver (the size of which depends on the model and make of your table saw, so ensure that you read through the instruction manual for specifications)
  • A hex wrench
  • A block of wood
  • A new table saw blade
  • Protective gloves and eye gear

Once you have all you need, you can follow the below guide. It will show you how to change a table saw blade in a hassle-free and quick way.

Step 1

First things first – unplug the table saw from the power socket and place the plug where you can see it for assurance that the machine is not powered. The last thing you need is an accident that will cost you your fingers and high medical charges to repair the damage done. It’s advisable that you wear protective gloves and eye gear to protect against any debris on the machine, but you can judge for yourself whether you need to wear these or not when preparing to change the blade.

Step 2

You want to change the blade in a careful and controlled manner to minimize any possible damages, especially to yourself since the teeth of the blade are quite sharp. You can use the tools that come with the table saw, which are more than enough to do the job efficiently and effectively, or you can use your other wrenches to do the blade change.

To get started, remove the throat plate from the table saw. After doing this, place your wrench on the nut located on the arbor.

Step 3

At this point, you’re getting ready to loosen the nut from the arbor. Take your block of wood, put it in between the teeth of the blade, and push it gently to loosen the nut. You can then take out the nut, the cup washer, and the old blade.

The reason for placing the block of wood in between the teeth of the blade and not in front is because you want to minimize the chances of hurting yourself during the change process. Should you place the block of wood in front of the blade and try to yank it out of position, there’s a high chance that you’ll rake your hand on the blade’s sharp teeth.

Another method you can use to change the old blade is to fit the wrench on the nut securely. The wrench will balance on the table. Raise the blade to make it easier for you to take hold of it.

The teeth of the blade should be in the opposite direction, minimizing the chances of you hurting yourself. Push the blade forward in a gentle manner until the nut loosens. You can then take the nut off, followed by the cup washer and then the old blade.

It’s great practice to clean the arbor threads with a stainless-steel brush. This type of brush won’t scratch the arbor threads because of its softer bristles. With it, you can clean off any residue left on the machine from the hard work it’s been doing. You’re now ready to place the new blade on the table saw.

Step 4

As you mount the new blade on the arbor, make sure that the blade’s teeth are facing towards you. You will most likely change the blade in the same position that you assume when using the table saw.

When you place the cup washer on the blade, ensure that the concave side faces towards the blade. After this, place the nut on the arbor and tighten it as much as possible with your strength. Apply a little bit of force with your wrench, but be careful not to tighten the nut too much as you can damage it. The general rule of thumb is to tighten it a quarter more than finger tightness. After mounting the new blade, make sure to check the alignment of the blade with the miter slot.

Step 5

Reconnect the table saw to the power socket for testing purposes. When you switch the machine on, run the blade to see if it’s installed correctly and operating as per usual. If the blade starts shaking or vibrating, it means that you haven’t installed it correctly. If it runs smoothly, it means you’re ready to operate the machine. To test it out, cut a piece of wood.

Now that you’ve already learned how to change a table saw blade, you can see just how the entire process is quick and easy. Like anything in life, the more you change table saw blades, the easier and faster the process becomes. One thing to keep in mind is to remember to disconnect the machine from
