How to Replace a Miter Saw Blade Guard

What You'll Need

A miter saw is equipped with a special, curved piece of metal that shelters the saw blade, which is called a blade guard. You only need to move the blade guard up and down when you need to replace the saw blade, and you can usually do so automatically or manually. Unlike the saw blade, however, you don’t typically need to replace the blade guard; you would only need to do so if you somehow broke it, if it became sticky and no longer lifted up and down, or if it became loose. If this is the case, then check out this handy guide to find out the best way to replace the miter saw blade guard.

Step 1 – Order a New Blade Guard

A miter saw blade guard isn’t necessarily something that you can buy at your local hardware store, since it isn’t a part that needs to be replaced very often. You will probably need to order a new blade guard from the miter saw’s manufacturer. Make sure to specify the exact model, so that the new part will be a perfect match.

Step 2 - Unplug the Saw

Before you can do anything else, you need to make sure that the miter saw is unplugged, and that there’s no chance that it could get powered up at any point. This is the most important safety step of the entire process; you don’t want any nasty surprises! Also, whenever you’re working with the sharp, spiky blades of a saw, it’s a good idea to keep your eyes protected with some safety goggles.

Step 3 – Loosen the Nuts and Bolts

The next step is to loosen the nuts and bolts that hold them in place. Depending on the model of miter saw you have, you might need different tools to do so. For example, you might need to use an Allen wrench or a flathead screwdriver. Twist the nuts out of place and remove them. Lift the blade guard out of place, taking care not to cut yourself on the blade below.

Step 4 – Attach the New Blade Guard

Put the new blade guard in place on your miter saw. Affix the nuts and bolts and be sure to tighten them into place as firmly and securely as possible. You might want to use this opportunity to check the entire saw, and tighten up every part that you can: make sure that the blade isn’t loose and wobbly, or the spindle either. In fact, if you managed to damage the blade guard, there is a chance that damage could have been done to another part of your miter saw. For this reason, take the time to make sure that everything is working as it should before you use the saw on your next DIY project.
