2.3 Greasing
The ball screw spline and reduction gear units need greasing regularly. Only use the grease
specified in the following table.
CAUTION
■
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. Once the parts are damaged, a lot of time and money will be
required for the repairs.
CAUTION
■
If grease gets into your eyes, mouth, or on your skin, follow the instructions below.
If grease gets into your eyes
: Flush them thoroughly with clean water, and then see a doctor
immediately.
If grease gets into your mouth
: If swallowed, do not induce vomiting. See a doctor immediately.
: If grease just gets into your mouth, wash out your mouth with water
thoroughly.
If grease gets on your skin
: Wash the area thoroughly with soap and water.

Greasing the Ball Screw Spline Unit
(See below)
Joint #1, 2 reduction gear units
As a rough indication, perform greasing at the same timing as overhaul.
However, it may vary depending on ambient temperature, 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.
Joint #3 Ball screw spline unit
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.
Normal grease Discolored grease
Perform greasing at 50 km of operation for the first time of greasing.
For the EPSON RC+ 7.0 Ver. 7.2.x or later (firmware Ver.7.2.x.x or later), the
recommended replacement time for the grease on the ball screw spline unit can be checked
in the [Maintenance] dialog box of the EPSON RC+ 7.0.
For details, refer to the following manual.
