Gosmeta D135 Lathe (appears identical to the Gromatic 140 and the manual is for that machine ). Operation & Maintenance Manual with useful Sectional Drawings and Electrical Schematics. The lathe shown has two separate levers on the front of the stand to change the spindle speeds. The Gromatic with the two levers mounted on a common shaft is otherwise identical. While perfectly readable, this manual is not to our usual very high standards of reproduction.
