(3) To grease ball screws, first clean, then put some grease on your finger and apply while moving the slider
back and forth.
In this process, pay attention to the stainless steel sheet so that you would not touch and make it
deformed.
When finished, wipe off excess grease.
(4) Attach the side covers after grease supply is finished.
If you touch the edge of the stainless sheet in the attaching process, the sheet may get damaged or
wavy which result in shortening life or earlier wear-out.
To avoid touching the edge of the sheet, insert a spacer (approximately 0.1 to 0.2mm) between the
sheet and cover to push up the sheet, and then push in the cover.
Caution: x Do not damage the stainless steel sheet by bending it forcefully during the check inside.
Also you may get hurt on the edge of the stainless steel sheet. Wear gloves when you work
on it.
The front cover is supporting the ball screw. Do not detach it.
If the front cover loses its tuned condition, it may cause an increase of slider resistance,
shorten production life and abnormal noise due to the center of the axis being off the right
position.
x In case the grease got into your eye, immediately go see the doctor to get appropriate care.
After finishing the gease supply work, wash your hands carefully with water and soap to
rinse the grease off.
