NOTE
Basically, the lubricating the spline shaft (Z-axis) is not required. However, the grease on the spline shaft surface is
removed by touching with hand or by sprinkling solvent. As a result, the spline shaft gets easily rusted. Apply the
specified grease (NSL) slightly for anti-rusting as needed.

How to replace consumable parts
