level
Please observe the following before commencing any repair work on the manipulator:
- Motors and gears are HOT after running the robot! Burns may result from touching the
motors or gears!
- Turn off all electric power, hydraulic and pneumatic pressure supplies to the robot!
- Take any necessary measures to ensure that the manipulator does not collapse as parts are
removed, e.g. to secure the lower arm with fixtures if removing motor, axis 2.
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!
