inspect the robot for any signs of oil in areas immediately outside of the Harmonic Drives.
Check these locations:

the area around Joint 1

the area around Joint 2
l
inside the base of the robot, by opening the eAIB chassis and inspecting internally.

Remove all power to the robot before opening the eAIB chassis.
Contact Omron Adept Technologies, Inc. if you find any signs of oil in these areas.
