How to Select the Correct Variant
Confirm the cutting-head series, complete part number, installed optical position and any listed focal or optical specification before ordering. Do not select a focusing unit only by the external housing because similar assemblies can contain different internal configurations.
Why Correct Selection Matters
Correct model identification helps avoid purchasing an incompatible optical assembly and reduces unnecessary disassembly during maintenance. Send the original label, mounting details and cutting-head nameplate when requesting compatibility confirmation.
