Note
Action
Note
1. Move the robot to one of the recommended
positions:
•
to a position where the motor in axis 6 is
pointed straight up. This position enables the
motor to be replaced without draining the
gear oil, which in turn saves time.
•
to a position where the motor in axis 6 is
close to horizontal. This position may be
selected when the gearbox is to be replaced,
i.e. when the gearbox oil has to be drained
anyway.
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. In horizontal position: drain the oil from the axis 6
gearbox.
