Manuals and Catalogues
POREBA (FUM) Lathes Types TR70B and TR70C Operator's Instruction and Maintenance Manual with a Parts Manual as large sectional drawings (many with dimensions making the manufacture of replacements possible) and a Hydraulic Schematic. Also included are some electrical diagrams showing connections for the various motors and the hydraulic copying attachment - though these do not appear to be full electrical schematics. This manual is typical of the communist-era types being printed on a dark paper using a spirit duplicator, hence the quality is not terribly good.
