13. Maintenance Inspection
(2) To grease ball screws, first clean, then put some grease on your finger and apply while moving the
slider back and forth.
If the side cover and stainless sheet are present, put them back on.
(Note) There is no side cover for RA2AC and RA2AR.
Remove the stainless steel sheet and apply grease to the guide from upper side.
When finished, wipe off excess grease.
Caution: When moving the slider back and forth by hand, be certain never to apply force in excess
of the thrust direction external force capacity (see 11.1.2). (If the slider will not move,
operate it using a jog function.)
Caution: In case the grease got into your eye, immediately go to see the doctor to get an
appropriate care.
After finishing the grease supply work, wash your hands carefully with water and soap to
rinse the grease off.
