■ When with the brake release unit or the external short connector:
If the Manipulator is operated without connecting the brake release unit
or the external short connector, the brakes cannot be released, and it
may cause damage on them.
After using the brake release unit, be sure to connect the external short
connector to the Manipulator, or check connection of the connector for
the brake release unit.

While pressing the brake release switch, be careful of the arm falling
and rotation of the hand due to its own weight. It may cause
pinching of fingers, damage to the manipulator, or malfunction.
Normally, release the brake of joints one by one. Take extra care if
you need to release the brakes of two or more joints simultaneously.
Releasing the brakes of two or more joints simultaneously may result
in hands or fingers being caught and/or equipment damage to or
malfunction of the Manipulator as the arms of the Manipulator may
move in unexpected directions.
Be careful of the arm falling when releasing the brake. While the
brake is being released, the Manipulator's arm falls by its own
weight. The arm falling may result in hands or fingers being caught
and/or equipment damage to or malfunction of the Manipulator.
Before releasing the brake, be sure to keep the Emergency Stop
switch handy so that you can immediately press the Emergency
Stop switch. Otherwise, you cannot immediately stop the arm falling
due to an erroneous operation. The arm falling may cause
equipment damage to and/or malfunction of the Manipulator.
