Action
DANGER
Turn off all:
• electric power supply
• hydraulic pressure supply
• air pressure supply
to the robot, before entering the robot working
area.
WARNING
Handling gearbox oil involves several safety risks,
see Gearbox lubricants (oil or grease) on page
Do a leakage check of the sight glass/evacuation
hole of each motor.
If any oil is available on the sight glass or if any
oil has been spilled out from the evacuation hole,
replacement of the motor is recommended.
Note
If oil is present in the evacuation it is an indication
that the primary seal of the motor is leaking. A
secondary seal after the evacuation is keeping
the oil out from the motor, but it is still recommen-
ded to replace the motor at a suitable timing if oil
is present in the evacuation.
