This is a .pdf download of the instruction manual for the Necchi Lydia Mark 2 versions of the 542 & 544 machines.
These is the type with the bobbin winder on the end of the motor, towards the back of the machine (see diagram). If your winder is at the front, right next to the hand wheel, you will need to see the other listing.
This is the second incarnation of the Lydias. The most obvious differences from the original are the different position of the winder & larger thread spool pins. It still has the small round push button for reverse stitch.
38 pagesand UK postage and packing on printed versions is free.
This manual is also available as a printed hard copy.
