Manually Retract the Robot

Manually retract the robot when you cannot park the robot by using the power-down procedure.

1. Always attempt to have the library park the robot before attempting this procedure (see Park and Lock the Robot).
2. Remove the top drive tray from the Base Module (see Drive Tray Removal and Replacement).
3. Locate the bullwheel gear inside the library and above the top drive slot (see image below).
4. Look through the drive slot and locate the position of the robot.
5. Turn the gear with your thumb to raise the robot, hold the gear in position with a finger, reposition your thumb, and turn the gear. Repeat as necessary until the robot is at the top of the Base Module.

   If the robot does not retract, disengage it (see Manually Disengage the Robot).

6. Hold the bullwheel gear with the robot fully raised until you lock the robot.
7. Return to Step 5 of Park and Lock the Robot and continue through the last step of robot removal (see Slide Robot CRU Out of Base Module).
