    • Quality of material. CINCINNATI machines are designed to be rugged and durable. However, improper adjustment or lack of maintenance can reduce the quality of parts produced on that machine. These factors may also affect the repeatability of the machine. A machine that will not consistently reverse at the same point or will drift out-of-level will not produce uniform parts.
  • Page 6 MANUAL GUIDE To get the maximum benefit of your new CINCINNATI INCORPORATED machine, read this manual thoroughly and refer to it often for guidance and information. IMPORTANT: Before you operate the machine, read and understand thoroughly, Section 3 on Safety.
