Greasing - Epson T-B Series Maintenance Manual

2.3 Greasing

The ball screw spline and reduction gear units need greasing regularly. Only use the grease
specified in the following table.
■ Keep enough grease in the Manipulator. Operating the Manipulator with
insufficient grease will damage sliding parts and/or result in insufficient function of
the Manipulator.
CAUTION
■ If grease gets into your eyes, mouth, or on your skin, follow the instructions below.

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
For the EPSON RC+ 7.0 the recommended replacement time for the grease on the ball screw

spline unit can be checked in the [Maintenance] dialog box.
Refer to "4. Alarm".
