Action
Remove the mechanical stop pin from the
frame.
Drain the axis 1 gearbox.
Loosen the cable connectors from the base
and pull up the cabling from the base,
through the hole in the center of the frame.
Remove the axis 1 motor.
CAUTION
The robot arm system weighs 750 kg.
All lifting accessories used must be sized
accordingly!
Fit the roundslings as described in
lifting accessories to the complete arm sys-
tem on page 178.
Stretch the roundslings so that they secure
the weight of the arm system.
Unfasten the arm system from the base by
unscrewing the attachment screws.
Note
Use a bits holder with a thin head to remove
the screws. For example Stahlwille 736/40
D10 or similar. The space is cramp.
Fit two guide pins in the holes. This will facil-
itate the removal of the complete arm system
and prevent damage on the gearbox.
