Action
WARNING
Handling gearbox oil involves several safety
risks, see Gearbox lubricants (oil or grease)
on page 32.
DANGER
Turn off all:
• electric power supply
• hydraulic pressure supply
• air pressure supply
to the robot, before entering the robot
working area.
CAUTION
The gearbox can contain an excess of
pressure that can be hazardous. Open the
oil plug carefully in order to let out the ex-
cess pressure.
If the robot is suspended, lift it down from
its suspended position and secure it on the
floor.
Then open the oil plug for inspection.
Measure the oil level at the oil plug hole.
Required oil level:
• 23 mm ± 3 mm below the lower edge
of the oil plug hole.
Add oil if required.
Refit the oil plug.
Note
Before refitting the oil plug in the gearbox,
always replace the oil plug sealing washer
with a new one. If not there is a risk of
leakage.
