Model 412 Tube Bender/Maintenance and Parts List
Bender Maintenance
All parts should be kept clean and free from dirt and
grit. Slide block and radius blocks should be handled
carefully to avoid damaging the smooth grooved surfac-
es. Presence of nicks, burrs, pieces of dirt or chips may
mar the surface of the tube and thereby weaken it.
All threaded parts should be cleaned and slightly
greased occasionally to keep them in good working
condition. This equipment will operate efficiently for a
long period of time and will bend to exact tolerances
repeatedly if these precautions are heeded.
