Singer 401, 401A Service Manual (printed from this CD). (photo 02)

Description:

This listing is for a professional reproduction of the Singer Manufacturing Co. Service Manual for Singer 401, 401A sewing machines. This is NOT a standard "Xerox" copy of the Singer manual! This manual is precisely scanned using a professional high-resolution scanner, to prepare an exact duplicate of the original Singer manual on a CD, in PDF format.

Unlike most original 60 year old manuals that have become frail, brittle, mildewed, stained and yellowed after so many years, this manual looks like an original Singer manual that has been preserved in MINT CONDITION!

Just like a new Singer manual, this manual on CD is complete with all the original text, diagrams, tables, and photos. It is super clean with no stains or any other imperfections!

This manual on CD is in easy to use PDF format. All the pages (including the color cover pages) and diagrams are readable on your computer monitor screen and are also easily printable.

You will be able to view and read page by page on your monitor screen, print any single page, or print the entire manual, if you so desire.

Almost all computer users have a PDF reader. However, if you need a PDF reader, you can download a free Adobe Reader from the following link: get.adobe.com/reader/

If you ever decide to print the entire manual, including the 2 cover pages, it will most likely look exactly like the original Singer manual.

We printed the entire manual from this CD

on 24 Lb semi-gloss off-white paper,

and the resulting manual is almost identical

to our original 60-year old Singer manual.

The printed manual is super clean with no stains or any imperfections.

you could not tell the difference

between this manual, printed from the CD,

and our original Singer manual!

This 42-page full-size Service Manual on CD is complete and very clean with no "black dots," smudges, stains, or any other imperfections. No pages are missing, dirty, or damaged.
