ABB 3HAC084741-003 stores mechanical energy, so the IRB 7720 arm must be supported, robot power isolated and spring preload neutralized before attachment hardware is loosened.

ABB 3HAC084741-003 is identified by its complete ordering record, finish and IRB 7720 attachment geometry; a similar-looking balancing device may use different pivots or preload execution.

For ABB 3HAC084741-003, record arm position, pivot orientation, spacer order, attachment hardware and finish so the replacement follows the same mechanical path.

After ABB 3HAC084741-003 is secured, remove supports in the specified sequence and move the IRB 7720 slowly through a controlled range while watching for binding or abnormal counterbalance behavior.

ABB 3HAC084741-003 is documented as a complete balancing-device record; using an unrelated spring would not preserve its housing, pivots, preload and attachment geometry.

The Graphite White finish is part of the ABB 3HAC084741-003 service identity and helps keep this record separate from other physical executions used on related manipulators.
