WARNING
Handling gearbox oil involves several safety
risks. Before proceeding, please read the safety
information in the section
work with gearbox lubricants (oil or grease) on
page 40.
Move axes 3 and 5 to a horizontal position, and
make sure that the oil plug, filling and inspection
is facing upwards.
DANGER
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.
Remove the oil plug, filling and inspection.
Slowly turn axis 4 until the axis-4 angle reads
+72.5° to +77.5°.
Inspect the oil level in the hole for the oil plug,
filling and inspection.
The oil should reach all the way up to the extern-
al edge of the thread for the oil plug, filling and
inspection.
Note
If needed, use a clean, narrow object, for ex-
ample 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.
