Maintenance 10. Greasing and Replacing the Ball Screw Spline Unit
E2C Rev.6

10.3.2 C, CM Type Manipulators
A large amount of dust is emitted during the greasing procedure because the bellows must
be removed. Before greasing the ball screw spline unit of the C or CM type, take the unit
to an outer room such as the room in front of the clean room’s entrance, or take the
necessary countermeasures to prevent dust emission.
Do not allow any grease to get on the outside of the bellows while greasing.
Cover the surrounding such as the end effector and peripheral equipment in case the grease
drips.
