I had a Brother 1034d and you will find it is much much better to tie on your new thread rather than re-thread. I always loosened up the tension dials to let the new thread pull through easier. As I recall it was a real pain to get that upper looper threaded. I had to read manual and watch the dvd each time I changed thread. Because of that I finally sold that machine and bought a singer serger. But really found out that they are all the same, just a pain to thread.
