As a rough indication, perform greasing at the same timing as overhaul.
However, it may vary depending on usage condition and degree of the load (such as when
operated with the maximum motion speed and maximum acceleration / deceleration in
continuous operation) applied on the Manipulator.

The recommended greasing interval is at 100 km of operation. However, greasing timing
also can be checked from the grease condition. Perform greasing if the grease is
discolored or becomes dry.
Perform greasing at 50 km of operation for the first time of greasing.
NOTE
Recommended replacement time for the grease on the ball screw spline unit can be
