SERVICE Manual for Necchi 542 544 Sewing Machine - 35 pages.

"This booklet is intended for the mechanics who devote themselves to the maintenance and repair of sewing machines, i.e. mechanics provided with more than a general knowledge of the machines in question.

For this reason we have on purpose omitted to describe theoretically the disassembly, assembly and regulations of parts which are common in all sewing machines."

Our manuals are printed copies, sized 8 1/2 × 11 inches and bound with a clear plastic front cover, a plastic comb spine so that they can lie flat when opened, and a cardstock back cover. 
Most are enlarged from the originals.
