I have the Brother 1500 and the thread would pull out of the needle when using the thread cutter. The dealer kept saying buy a new thread cutter. Why it was brand new! A poster here told me to by pass the three hole bar or use only the first hole and have the thread go down the hole not come up underneath the hole like the picture shows. The bar is used to add more tension to thread. My needle doesn't come unthreaded anymore.
