I have a Bernina and I know what you mean. I found the trick of lifting up on your presser foot handle, even when its up gives you just enough room, as one finger is holding up the presser foot lever, come from the back and bring the foot forward. As you bring it forward, lift the bar with the fork to fit the needle screw. and then bring the lever bar down to secure it. I hope this makes sense. Lifting up on the lever is the trick. Good luck
