Action
DANGER
Turn off all:
• electric power supply
• hydraulic pressure supply
• air pressure supply
to the robot, before entering the safe-
guarded space.
WARNING
Handling gearbox oil involves several
safety risks, see Gearbox lubricants (oil or
grease) on page 29.
Make sure that the oil temperature is +25°C
± 10°C.
CAUTION
The gearbox can contain an excess of
pressure that can be hazardous. Open the
oil plug carefully in order to let the excess
pressure out.
Remove the plug from the venting hole.
WARNING
Let the venting hole stay open during
draining and filling using the dispenser, to
avoid damaging vital parts in the gearbox.
