BLADE remove/install
To remove the blade, turn the knob, on top of the saw, over the blade holder, counterclockwise until it stops. Remove the blade, then , after installing a blade turn this knob clockwise to tighten the blade. (the knob turns many times, before stopping at the "Lock" or "Unlock" positions)-Bob Curry
