Once I had a chance to look over the service paperwork I paid for a whole sheet of work for only 70.00. Going to the dealer for that I would have paid at least twice as much. He showed my husband the screws to take out of the bottom and how to thoroughly clean the bottom of the machine. He thinks anyone who sews on a regular basis should be able to clean their machine themselves. He's a super nice man and now hubby will be digging out the old garage. I want to make sure I know how to thread that sucker cause it's a bit complicated. I'll probably post what model it is when I know and call brother to see if I can get an owner's manual for it.
