Turn off all:
• electric power supply to the robot
• hydraulic pressure supply to the robot
• air pressure supply to the robot
Before entering the robot working area.
Make sure that the oil temperature is +25°C ±10°C.
Open the oil plug, filling and inspection.
Turn axis 6 so that the oil plug, draining faces up-
wards.
Open the oil plug, draining.
Slowly turn axis 4, while adjusting axis 6 so that the
oil plug, draining always faces upwards. Turn axis
4 until the axis-4 angle reads -45° to -55°.
Inspect the oil level in the hole for the oil plug, filling
and inspection.
The oil should reach all the way up to the external
edge of the thread for the oil plug, filling and inspec-
tion.
Note
If the oil plug, draining is not opened, then use a
clean, narrow object, for example an oil stick or a
cable tie, to gently poke the oil surface. This will
avoid surface tension from stopping air to enter into
the gearbox.

opened, then this step can be
skipped.
