Action Note
1. Move the robot to a position where the upper
arm is pointed straight up.
This position enables the motor to be
replaced without draining the gear oil, which
in turn saves time.
Any other position of the upper arm requires
a draining of oil from the gearbox for axis 4.
Draining of oil is described in section
Draining, oil on page 175.
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. Remove the cable gland cover at the cable
exit of the motor by unscrewing its two
attachment screws.
Shown in the figure Location of motor on
page 342.
