Just to add a note...we have 4 3494s of various ages. It seems that the older ones had a shiny metal helix that was covered with lubrication, but the newer library's helixes are covered with some black Teflon-like coating. I ~believe~ that our IBM CE said that no lubrication was necessary on these new helixes.

The robotic actuator achieves vertical motion via a roughly 5' tall steel helix. The helix is lubricated with a grease. Over time, the grease dries out - and solidifies. The robot then strains to gain elevation, which over-taxes the vertical drive motor and causes an electrical Intervention Required. The associated panel message specifies an IBM service call. They will respond by cleaning and re- lubricating the shaft. To prevent an outage of some hours, you may want to assure that your CE is performing periodic re-lubrication of this assembly. One would think that it would be on the list of PM tasks, but apparently it is not. Other robotic library types may have a similar vulnerability. Richard Sims
