Answer
The tensioner rotates on an eccentric.  The hole in it is off center so as you rotate it it pushes against the belt.  Rotate it counter clockwise to remove the belt and clockwise to tighten  But if you take the nut all the way off it makes no difference for it just holds the tensioner pulley down. it does not control the tension.  You have to push something against the wheel so the belt tightens up and tighten the nut.
