Note Action
Draining of oil is described in section
Draining, oil on page 154 .
Move the robot to a position where the upper
arm is pointed straight up.
This position enables the motor to be re-
placed without draining the gear oil, which
in turn saves time. 2
Any other position of the upper arm requires
a draining of oil from the gearbox for axis 4.
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.
