Step 1:

As it is a power saw, it should have an attachment to the electrical outlet. So unplug the power cord from the extension cord. There is also a cordless circular saw. For a cordless circular saw, you need to remove the battery.

Step 2:

There is an arbor lock button on the circular saw. Pressing down the arbor lock button, rotate the blade so that the locking mechanism engages. Without touching the button, you can’t turn the blade so remember to press it down.

Step 3:

When removing the arbor nut, hold the blade in place. The next thing you need to do is loosening the nut. In which direction the blade cuts, turn the wrench in that direction for loosening the nut.

Step 4:

Retract the circular saw’s top blade guard. And then remove the old blade which you need to change.
