Best of luck Gavin Posted on Apr 10, 2009. When you are turning the knob clockwise this time it's supposed to click in place but my one doesn't do this and still seems to work. Replacement is, as they say in all the best manuals, a simple reversal of the procedure. Then take hold of the blade, ease it forward and turn through 90 degrees. Theoretically you should turn the knob anticlockwise three turns but it doesn't seem to make any difference on my one.

Be careful not to tip your saw over while the screw is loose. Tighten up the clamp screw and you're good to go.

Once the clamp screw is loosened, twist the blade about 90 deg and you should be able to pull it out (don't cut yourself, by accident) Put the new blade in with the same orientation and twist so the blades are facing the front of the saw. Use a long thin blade screw driver to loosen the clamp screw. In the handle directly over the blade there is a hole with a clamp screw at the bottom. Unplug the saw before you change the blade. I mention it, because it shows the clamp screw which hold the blade in place (35 on the diagram). There's an exploded diagram of a similar model.
