I have a Singer industrial overlocker model # K60473 ...? how to thread it or a manual that I could get to see on line
If you have a singer industrial overlocker start by winding a bobbin and then place the spool of the thread on the rear arm or the post. See the link below for more about this http://www.wikihow.com/Thread-a-Sewing-Machine.
Have you tried the Singer website? You will likely find help there or a contact number or link.
