No. 6800 Quick Change Gear Mechanism Operating Instructions
Operating instructions for the Atlas No. 6800 Quick Change gear mechanism—an essential workshop manual for owners and operators of Atlas 10 inch metalworking lathes. This service manual covers the quick-change gearbox system in detail: proper lubrication using S.A.E. No. 20 machine oil, operation of all control levers (left hand lever with five selectable positions A–E, right hand lever with nine position options, reverse tumbler lever engagement, and sliding gear lever positioning), and interpretation of the quick-change chart for all 54 standard threads and feeds. Dedicated sections address cutting odd and metric threads, as well as coil and wire winding applications using standard Atlas change gears. Includes precise diagrams showing gear arrangement at each control position and a complete quick-change reference chart specifying threads per inch and corresponding carriage feed rates—everything needed to set up and adjust the mechanism correctly for different threading and feeding operations.
