Action
Move the upper arm to one of the basic pos-
itions:
•
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.
•
upper arm is close to horizontal. This
position is recommended if the gear-
box is also to be replaced, i.e. when
the gearbox oil has to be drained
anyway.
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.
