Basically,
fill the grease to the ball screw spline unit every three (3) months.
If you have verified that there is not much grease, be sure to apply grease.
At daily inspection also, make sure that the ball screw spline unit is filled with a
sufficient volume of grease.
Check the condition of anticorrosive in daily inspection. If anticorrosive is dried up,
apply it.
