Number of Pages: 21 This is a reproduction, not a photocopy, of an Atlas 12" Bench Top Metal Lathes for Models 3985 and 3986 Instructions and Parts Manual. The manual covers how to properly mount the Atlas lathe and motor on a bench. It contains information on setup, lubrication, maintenance, and adjustments. The manual also contains clear and easy to read explosive view diagrams of all the parts with parts descriptions. This would make it easier to take apart to work on, or order new parts for the Atlas 3985 and 3986 lathes. These models were manufactured in the 1970's. We also have the Manual of Lathe Operations that would cover these model. I highly recommend this book, because it covers how to properly operate a metal lathe, includes the threading charts, and shows how to use all the attachments Atlas made for this lathe. We carry 6 different versions of this book to cover the different models the one that covers the Atlas 3985 and 3986 is located at this link: Atlas Craftsman Manual of Lathe Operation Book for 12″ Crossfeed Lever Contents: Installation: Mounting Lathe on Bench...................................4&5 Leveling....................................................6 Lubrication Lubrication Chart...........................................7 Controls And Operation Back Gear Controls..........................................8 Changing Spindle Speeds.....................................8 Headstock...................................................8 Quick-Change Gear Box.......................................9 Carriage....................................................9 Tailstock..................................................10 Sequence of Engaging Controls..............................10 Chucks and Face Plates.....................................11 Maintenance and Adjustments
