Automatic hinge pin door closer? I wasn't sure if BOTH toothed legs were supposed to touch the...

I wasn't sure if BOTH toothed legs were supposed to touch the door hinge, or stay 1/2 inch apart. I rotated the stiffness collar counter clockwise after making sure one toothed leg touched the door hinge tightly. I then put the lock pin vertebrae in and tried the door to see if it would shut by itself. Nothing. Did I turn the stiffness collar too far counterclockwise? Is it possible to return the toothed legs to 1/2 inch apart and start over...or once you turn counter clockwise, is it too late?
Thank you.

Answers:    respectively of the toothed egdes need to touch respectively of the outsides of the hinge

then you will know how to adjust the tensioner properly and be careful if you dont grasp that little pin in place philosophical enough to hold since moving that tiny little allen wrench for another grip it will fly across the room breaking anything in the track
