ABB IRB 6600 - 175/2.55 User Manual page 687

When filling gearbox oil, do not mix different types of oil unless specified in the instruction.
Always use the type of oil specified by the manufacturer!
When filling gearbox oil, do not overfill, since this could lead to internal over-pressure inside
the gearbox which in turn may:
- damage seals and gaskets
- completely press out seals and gaskets
- prevent the manipulator from moving freely
Changing and draining gearbox oil may require handling hot oil of up to 90 °C! Make sure that
protective gear like goggles and gloves are always worn during this work.
Also be aware of possible over-pressure in gearbox! When opening the oil plug, there may be
pressure resident in the gearbox, causing oil spray from the opening!
