Hey Frudemoo, I've inherited the same machine from my gran who was a seamstress but we had a problem trying to get hold of the secondary belt so my dad took it to a shop and we have discovered today (even though the guy never managed to get us the belt) that the guy in the shop had pulled apart the tension knob and put it back together wrong so now we are struggling to set the tension on it and when it is machining instead of it being perfect as my grab has left it, it now keeps looping on the underside really badly. We don't have any instructions with the model and so am trying to get hold of some. I saw your post and that is why I have joined. I need help, please can you come back to me. Thanks.
Jo
