Description:

This listing is for a professional reproduction of the Singer Manufacturing Co. Service Manual for model XL-400 sewing machines. This is NOT a standard "Xerox" copy of the Singer manual! It is professionally printed on the same heavy-weight pure-white paper as the original Singer manual! It is super clean, the text and the illustrations are very sharp, and it is nearly identical in size and in paper type to the original Singer manual. This manual is not a bunch of pages stapled at the top corner. This manual is professionally bound, just like the original Singer manual.

This manual is professionally bound,

just like the original Singer manual.

***************

Unlike the original 10 year old manual that has become frail, brittle, mildewed, stained and yellowed after so many years, this manual looks like an original Singer manual that has been preserved in NEW CONDITION!

Just like the Singer company printed their manual on their in-house printing press, we printed this manual on our in-house printing press.

In fact, if we didn't tell you,

you could not tell the difference

between this manual and the

original manual!

This 46-page full-size Service Manual is complete and very clean with no "black dots," smudges, stains, or any other imperfections. No pages are missing, dirty, or damaged.

These service instructions are very detailed and utilize diagrams and illustrations to make it easy to understand and carry out the instructions. In most cases a simple tool, like a screwdriver, is needed to do the task. And, once you know what to do, you may be able to perform the timing or the adjustment in just a couple of minutes! And when needed, you may be able to expertly remove and replace every single part of the machine!

These Service Instructions are a

MUST

for every owner
