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 activity.
Also, be aware of possible pressure build up in gearbox! When opening the oil plug, there
may be pressure present in the gearbox, causing oil to spray from the opening!
When filling gearbox oil, do not mix different types of oil as this may cause severe damage
to the gearbox! Always use the type of oil specified by the manufacturer!
If the oils are mixed, the gearbox must be thoroughly rinsed! Contact ABB for further
