I am in the process of doing a freshen up of my new-to-me horizontal mill (See Thread)
The challenge of this whole thing, is I have no documentation for this mill.
I would like to change the oil in the column gearbox and the knee (and the little Z axis reservior underneath).
I was able to scrub up a manual for a much larger machine from Summit (3UH). They mention the following:
That is the only place I see the oil specification listed. My questions are these:
1. This mill resides in a shop that is heated not to freeze. This means 45F in the winter and 90+F in the summer. Should I stick with the ISO 68? Does this even seem reasonable for this type of machine? (Remember, my manual is from a much larger machine).
2. I keep seeing the DTE numbered vs DTE Light/Medium/Heavy conversations. Which is appropriate here? Know that there is a flow sightglass in the column which shows oil pump flow, but only a fill gauge in the knee (making me assume there is no pump). There is a "safety clutch" which resides in the knee. I am not sure how it works exactly, but know that clutches were one of the deciding factors between DTE numbered and DTE L/M/H.
3. The machine has a horizontal head which is just gear driven, I assume I can use this same oil in the head? Same with the little Z axis reservoir where the screw rides underneath the knee?
Thanks for any info/opinions.

When using the machine when the temperature is under 59F, please replace the oil SHELL-TURBO 68 (TELLUS 68) with SHELL-TURBO 46 (TELLUS 46)
