The reason I ask is the max size thread for BN is V69 (Tex 70, Tkt 40 ) with a max needle size of 16 (100) while the CN max thread is V138 (Tex 135, Tkt 20) with a max needle of 22 (140). Could it be that there isn't enough clearance for V138 top and bottom thread causing the machine to jam on this thread combination as well as a timing problem? I would check the timing, the model of the machine and then try it with V69 (Tex 70) top and bottom. If V69 (Tex 70) works good then I would try various thread combinations. You may find that with V138 top thread you may have to use V69 (Tex 70) or V92 (Tex 90) in the bobbin. kgg Kgg, thank you for your advice. It is the CN model and takes Tex 135 thread top and bottom as well as 140 needle (and up to 180). My main thread is Tex 70 top and bottom and 140 size needle. So the problem was the machine was knocked out of time because of the thread jam and clutch engagement. I timed it again, everything works perfectly now. Thank you all for you intervention. One last question: does anybody among you have service (or/and user) manual for Pfaff 1245-706/47? Thank you all for help, Gregor Quote

I recommend using a #110 needle with that thread size.
