Touch it! I was allowed to take it apart! i have been sewing for 66 years, gone through lots of machines til I got my Viking DIamond for embroidery...and I did take a screw driver to it...well, I changed needles, feet, took off the bobbin cover plate, took out the assembly, took the embroidery unit off and reinstalled it. I don't want a surprise when I get home...lots to learn on a new machine, so spending some time to get acquainted with it is only the smart thing to do.
