Description:

This listing is for a 44-page professional reproduction of the Singer Manufacturing Co. “Service Manual for Classes 337 and 338 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.

Just like the Singer manual, this manual on CD is complete with all the original text, diagrams, tables, and illustrations.

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 28 Lb heavy-weight brilliant-white paper,

and the resulting manual is almost identical

to our original 50-year old Singer manual.

The printed manual is super clean with no stains or smears.

This 44-page Instruction manual on CD is complete and very clean with no "black dots," smudges, stains, or smears. No pages are missing, dirty, or damaged.
