Begin by making sure that your miter saw is removed from the electrical outlet. Be sure that you have unplugged the correct power tool by squeezing the trigger that initiates the blade a few times. Next, loosen the screw that holds the blade guard in place and, using your hand, move the blade guard up and out of your way.

After doing that,you will need to press the miter saw's spindle lock to keep the blade secure. Make sure that the lock is secure when doing this. The lock is located in either the front, or the rear, of the saw housing and will be a little button that moves in and out. When you have the blade locked, the button will sink all the way down. Make sure the blade is locked into place before progressing.

Step 2 - Remove The Blade

Use an Allen wrench to turn the bolt that connects the blade to the saw in a clockwise direction until it is loosened. Then remove the blade’s outer washer. You can do this with your fingers. You will need to leave the inner washer in place.

Step 3 - Replace The Blade

Before replacing your miter saw blade, make sure that you consult your owner’s manual and follow manufacturer instructions for your miter saw, as they do vary slightly between brands.

Use a washcloth and wipe small drops of oil on the inner and outer washers that touch the miter saws blade. This provides lubrication for the saw. Lubricating your saw will keep it working properly.

Always install the blade with the teeth facing down. Improper installation of the miter saw blade can result in serious injury. After installing the miter saw blade, put the outer washer back on. Tighten it with your fingers. Then refasten the bolt by tightening it in a counterclockwise direction with your Allen wrench. Make sure that the blade is tight to avoid injuries. Using your screwdriver, reattach and lower the blade guard on your miter saw.
