3.6.5 Oil change, gearbox axis 5 and 6 (IRB 4400/L10 only)
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!
Action
Move the upper arm to a horizontal position and turn
axis 4 to the calibration position.
Remove the oil plug, draining in the wrist.
Turn axis 4 to a position where the oil plug, draining
is faced downwards and drain the oil into an oil col-
lecting vessel.
Also remove the oil plug, filling, in order to use it as
an air inlet.
Turn axis 4 another 90° to allow the remaining oil to
be drained.
Clean and refit the oil plug, draining.
Note
The specified amount of oil is based on the total volume of the gearbox. When
changing the oil, the amount of refilled oil may differ from the specified amount,
depending on how much oil has previously been drained from the gearbox.
