DANGER

If you begin maintenance on any servo motor which has a brake without securing it, a vertical axis may fall and cause severe personal injury or death, as well as mechanical damage!

Before performing maintenance on any servo motor with a brake, jog the vertical axis which the servo motor controls to a safe position.  Place supportive material to protect both the axis and the area onto which it is being placed before jogging the servo to a safe position.

If you are unable to jog the servo motor to safely position the vertical axis, use straps to secure it.  The following image is for reference only:
