Pam, I found the key to the manuel threader on Pfaff and Bernina 180 is to have the needle in the CENTER position, and at the highest point....it also seems I have to have the presser foot down...anyway, that appears to work. Love the ones that you push the button and they thread themselves...lol getting older and makes it easier. I remember when my grandmother used to ask me to thread a bunch of needles for her embroidery....it was so easy then.
