Inspecting the oil level in axis-6 gearbox
Use this procedure to inspect the oil level in the axis-6 gearbox.
NoteAction
WARNING
Handling gearbox oil involves several safety
risks. Before proceeding, please read the safety
information in the section Safety risks during
work with gearbox lubricants (oil or grease) on
page 38.
1
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.
3
This is a precaution to reduce the
temperature dependency of the
measurement.
Make sure that the oil temperature is +25°C
±10°C.

A Oil plug hole
B Required oil level
C Gearbox oil
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.
