I can testify to the fact that paying Vince Putnam (my tech) to do this procedure to my machines has payed off tremendously! My shops productivity has increased by more than 33%. He also told me that even new machines may need this done. I will agree because my newest machine now sews with no or very few thread breaks and at higher speeds than ever before. CALL YOUR TECH! It's worth the investment times 10!!!! =========================================================== The AmayaUsers Mailing List Website: http://www.amayausers.com Discussion Board: http://www.amayausers.com/boards Subscribe/Unsubscribe: http://www.amayausers.com/list ===========================================================
