Remove the supplied Allen wrench from it's nesting space in the front of the handle.

If the supplied Allen wrench is missing, a 6mm Allen wrench will suffice.

Depress and hold the spindle lock button located between the handle and blade shroud.

Using the Allen Wrench, unscrew the bolt holding the outer flange, blade (if installed), and inner flange.

If there is a blade currently mounted on your saw, wear gloves.
