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!
