depending upon the maintenance or repair procedure.
NOTE: Use only clean oil filtered to the SAE -recom-
mended cleanliness level of ISO 18/14 (ISO Standard
4406) when prefilling a system. The manufacturers of
the machine tool and its component bearings should be
consulted to ensure that the ISO 18/14 cleanliness level
is adequate.
