I put my blade in the quickclamp, all the way to the back of the clamp. I then lower the arm further until the blade starts to bend from being pushed down at the top of the clamp... I tighten the screw, release the arm and pluck the blade. Listen to it and adjust the tension until I get a high ping. Also that clamp should be secure in the holder, the knurl screw above it should be screwed down until the clamp is secure, no wiggle.. The regular clamps you need to live a little wiggle in the clamp. Yes the tension is a little fussy, but you get the feel of it. Took me a little while to get it right, once you do, it come natural. Had my for several years now, my favorite saw of the ones I have owned... BUT, it still makes me jump when a blade breaks...!
