[GreenKeys] Oiling or Greasing...

[Don Robert House]

At Illinois Bell we had all the manuals we needed to look up proper  
lubrication.
Some of the odd equipment like parallel to serial convertors and edge  
card readers and feeders, and Dataspeed stuff
needed special home work to work on.  However most of the regular  
machines had a couple of simple rules:

1.  Always keep lubricants away from the selector mechanism.  Keep the  
selector armature clean with bond paper.
2.  If a surface moves on or with another surface it needs grease.  If  
you see a bearing it will need grease.
3.  If there is a cotton wick it needs to be oiled.  Never let a wick  
get completely white.  Keep them looking either gray or yellow with oil.
4.  If there is a lubrication cap on something it needs to be either  
oiled or greased... look at the manual as not all caps were for oil.
5.  Watch for red colored areas.  Red usually indicates rust or  
corrosion or something way out of adjustment.
6.  More frequent light lubrication is better than heavy lubrication  
with long intervals.

Hope this helps.
