Unplug the Skilsaw Circular Saw

Don’t try to force a blade into a Skilsaw circular saw without knowing its size and requirements.

Look for the Blade Guard and Arbor

Like every other circular saw, Skilsaw also comes with a blade guard that protects the blade. So, place the saw on a firm surface and lift the guard to make sure the blade is exposed.

If your saw has an arbor lock, make sure it is locked in place. 

All modern circular saws have a spindle lock that has to be engaged before you remove the blade.

Remove the Bolts

Use a socket wrench to take out the bolts that are retaining the blade. Once the bolts are removed, the blade will be loosened and you can replace it.

Replace with New Blade

After removing the old blade from your Skilsaw circular saw, it’s time for the final step. Place the new blade properly, aligning it with the bolts.

Make sure that the teeth of the blade are angled downward on the front side of the saw. The blade should cut through materials smoothly when it’s spun in a clockwise direction.
