Draining oil
The procedure below details how to drain the oil from the wrist unit (axis 5 and 6).
Tip
When changing gearbox oil, first run the robot for a time to heat up the oil. Warm
oil drains quicker than cold oil.
WARNING
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!
