A brake is mounted on the motor of Joints #3 and #4 to prevent the shaft from moving

down due to the weight of the end effector while the power to the Controller is OFF or

while the motor is in OFF status (MOTOR OFF). (The brake for Joint #4 is only installed

to G6-**3**.)

Note that the brake will not work during the replacement procedure.

Move the shaft down to its lower limit before the replacement procedure following the

removal steps from (1) to (3).
