2.3 Greasing
The reduction gear units and the bevel gear need greasing regularly. Only use the grease
specified in the following table.
WARNING
■
Before greasing, turn OFF the Controller and related equipment, and then
disconnect the power plug from the power source. Performing any replacement
procedure with the power ON is extremely hazardous and may result in electric
shock and/or malfunction of the robot system.
CAUTION
■
Keep enough grease in the Manipulator. Operating the Manipulator with
insufficient grease will cause the noise or 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.
■ 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.

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.
