Step 2 – Engage The Safety Lock

Currently, almost all circular saws come with a lock button, knob, or lever. Look for that safety lock and engage it. The blade will not be able to rotate when the safety lock is engaged. Thus, a safety lock helps you in the next step by keeping the arbor nut stable.

Skilsaw circular saw have an arrow that indicates the direction of the blade’s rotation. Find it to know the direction of the rotation. It is important because you need to face the new blade’s teeth in the direction indicated by that arrow. You can use a hammer to drive the blade into the shaft if needed. 

Step 5 – Place And Tighten The Arbor Nut Again

After replacing the old blade with a new one, place the arbor nut at its place and tighten it. You should tighten it up to a certain limit. If you don’t tighten it enough, you may get yourself hurt. And if you tighten it too much, you will have to face difficulty replacing the blade next time.
