I found it best to tighten the screws then using a screwdriver inserted in the coil turns and just push down softly just so the coil sits 1mm above the juice flow hole. but check with some light behind it say on a lit up pc screen the coil is not touching the juice flow hole. also by lifting the end tags of the cotton, pulling them up then fitting the cap so the cotton ends are sticking out the end then trimming them by resting the scissors on top of the cap will leave a nice amount to tuck back inside around the coil. this worked lovely for me.
