    • Using a crescent wrench, unscrew the hex washer head screw that is holding the blade in place.

    • Lift the blade over the internally threaded screw and pull it off of the saw.

    • If the hex washer head screw rotates but does not loosen or if the whole blade rotates as you turn your wrench, giving the wrench a quick jerk should loosen the screw.
