For pressing arms

* The belt tensile jig and J1 brake positioning jig are assembly jigs. Use the jigs when adjusting belt tension.
The brake is mounted on each joint to prevent the arm from lowering due to its own weight while the Controller
power is OFF or the motor is OFF status. The brake does not work during replacement. Be careful when
performing maintenance work.
When removing the Joint #2 motor unit, tilt the Arm #2 and press it toward the Arm #1.

Reference:

Maintenance 6.1 Joint #2 - Replacing the Motor,

Removal step (2)

When pressing the arm, put a piece of cloth or a similar material between the arms to avoid contacting each other.
This protects the arm surfaces from scratching and paint peeling off.
