2) Supply grease 3 to 4 times with a grease gun.
3) Turn OFF the controller and move the Y-axis with hand for several rounds.
Caution: Ɣ Applying too much grease will increase the stirring resistance and may make
the ball screw easy to generate heat or make the excess grease on the ball
screw splash around with the rotation and dirt the surrounding. Do not supply
grease more than three or four times with a grease gun.
Ɣ 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.
