Doing some cleaning under the way covers.....reading the manual:

"To keep the EMC & TRM running smoothly, it is crucial that the ballscrews are
lubricated with MOBIL SHC #32 grease at least every 6 months depending on
use. Fadal recommends that a Fadal certified service person lubricate the
ballscrews."

I am confused as I do not see any zerk fittings under there....and doesn't the PDI do this already?

Some EMC, TRM and linear way mills had grease fittings standard with the PDI lube system as a option.
If yours has PDI to the screws it has been updated or was factory optioned with the lube system.
