How do you Remove the Head on a commercial embroidery machine head?

The best way is to watch a training video like this on greasing the rail on a commercial embroidery machine Head.  Whether you have a Tajima, SWF, HAPPY, Melco or Toyota embroidery machines, It's basically the same embroidery repair job.  The cost of repair calls can be overwhelming and not all embroidery technicians are the same.  The price of an embroidery repair call can vary from state to state.  You always want to ask how much will it cost? How much do you charge for a service call.  How much does that embroidery part cost?  Is this covered under my embroidery machine warrantee?
