I just bought a Toyota Expert AD-860 and have been trying to get it to stop breaking the thread. This machine had only 2M stitches on it when I picked it up. It seems to work at a very slow speed but when you speed it up, it breaks the thread. I am running it at mid speed with Floriani thread and stabilizer. I did not get a manual so I might have something set wrong. Please any help would be appreciated. Thanks!
