Checking for Oil Leaks

The robot uses oil in the harmonic drive components for lubrication. Periodically inspect the robot for
any signs of oil in areas immediately outside of the harmonic drive. Check these locations:
• The area around Joint 1.
• The area around Joint 2.
• Inside the base of the robot. Refer to Amplifier Chassis Replacement Procedure on page 6-14 for
information about about accessing the inside of the base of the robot.

Lubricating Joint 3

The joint 3 quill needs to be lubricated on a periodic basis of 3 months or 150 km of linear travel,
whichever comes first. 150 km of linear travel is approximately 2 weeks if a robot is operating 24 hours
per day for 7 days per week.
