Do's"  (for any sewing machine) Thoroughly read your manual!  Understand how the machine works, how to wind a bobbin and install, and how tension is adjusted. 
Don't get your fingers or thumbs any where near the needle ever.  If you need additional pressure near the foot... use a stilletto, chop stick or something like that.  
I'm still Jealous!!  *sigh* at this point I would take an old Singer Patch machine on a treadle.  lol 
Be sure to let us know how you like her....
