Bought a used but in good condition Craftsman 16 inch scroll saw. No info with it and was wondering what the large red knob on the end of the frame is used for. It has a black tightening knob on top. Red knob is marked "tension" and "release". Any help appreciated. Thanks, K-hornet

I have the same thing. just lift the black lever, then turn the knob to loosen the tension to replace the blade. flip the lever back down and turn the knob to tighten it back up.
