My old machine that I first used up until about 6 months ago had an instruction book which had no text only diagrams (Pfaff 30yrs old). This o showed that the presser foot show be threaded whilst in the up positon.
Which is what I have always done since being shown how to thread a machine by my mother when I was a child. So it's always been normal procedure for me to thread in the up position.
My new machine has an automatic threader which also indicates to thread in the up position. Hope this helps.
Happy threading :wink:
