Number of Pages: 15 This is a reproduction, not a photocopy, of an original Delta 16" Variable Speed Scroll Saw Model 40-570 with Quickset II Blade Changing Feature Owner Instructions and Parts Manual. This manual contains information on setting up and operating this scroll saw properly. It includes instructions for changing the blades and making adjustments. The manual also has explosive view diagrams of all the parts with parts list. Overview: I have collected this information for many years and have found the information they contain to be priceless in using and setting up the machines properly. I believe this manual will be a valuable resource of knowledge that will provide a lot of helpful information that is often hard to find. My manuals are not photocopies. I maintain a high standard of quality in my reproductions. Most of the manuals I reproduce look better than their originals. I have professionally digitally edited every page, and removed stains, wrinkles and handwriting. All of the manuals are printed on thick white paper to withstand shop wear and tear. This manual is clearer and easier to read than a .PDF download.
