New to Commercial Embroidery

Hello, I am new to this forum. Recently I inherited a SWF 1501C machine and need to know process to follow from loading the ready-to-stitch design to removing the completed design from the machine. I have all the manuals etcetera and have found some helpful videos, however, none of them tell you the step by step process. I have a domestic Janome MC 11000 machine but realized a commercial will operate much differently.

So if anyone can help me with this machine it would be greatly appreciate. I am looking forward to learning lots from this forum.
