After successfully fixing the hook timing etc. by a good tech over here i had this problem... The trimmer wasn't trimming correctly, sometimes it did sometimes it didn't.I decided to change the trimmer.I did it.Now the following happens :||| After cutting it ALWAYS gives bobbin error and if I take it out it's short cut and I have to manually fix and stitching restart correctly till the next cut...it's getting painful :||||| I solved a thread break problem with the tech (he properly aligned and configured the hook) and I had a bad thread cone. Now I have this bobbin thing :| I'm a bit depressed about it, especially because the tech are always involved and you are never able to fix using a normal manual.I understand it's a serious business but it's also frustrating to call the tech for everything :||| Any idea? :( Did i make something bad when changing the trimming knife? Is there any instructional video for maintenance etc. that i can use? =========================================================== The AmayaUsers Mailing List Website: http://www.amayausers.com Discussion Board: http://www.amayausers.com/boards Subscribe/Unsubscribe: http://www.amayausers.com/list ===========================================================
