Action
1.
WARNING!
Handling gearbox oil involves several safety risks.
Before proceeding, please read the safety
information in the section
during work with gearbox lubricants (oil or grease)
on page 44.
2.
DANGER!
Turn off all electric power, hydraulic and pneumatic
pressure supplies to the robot!
For Foundry Prime robots:
Do not turn off the air pressure to motors and SMB.
3. Make sure the oil plug, filling is facing upwards and
open it.
4. Turn axis to 85 degrees. Oil should now start to run
over. To much oil will give overrun before 85
degrees, to little oil in axis means oil will not spill
over until after 85 degrees.
5. Add oil if required.
6. Refit the oil plug, filling.
7.
WARNING!
Do not mix the oil types. If wrong oil is refilled, the
gearbox must be rinsed as detailed in the section
Type of oil.
