<Power tuning procedure>
1) Change the SET/RUN change-over switch g to the “RUN”
mode.
2) Set the auto width to “610 mm”. Keep the square button of the operation key i pressed for 3
sec. or longer to perform the power tuning.
At this time, pay special attention so that a portion between the transport rails does not interfere
with the light emitted from the optical fiber suitable for the amplifier being operated.

5-6. Replacing the Stopper Cylinder
1) Remove the hexagon nut c. The parts d, e, and f can then be removed.
2) Remove the hexagon nut g securing the cylinder. (Tool: Single-ended wrench, 11-size)
3) Detach the speed controller from the cylinder. (At this time, check what side the speed
controller has been mounted.)
4) When installing a new stopper cylinder, reassemble the components in the order of steps 3) to
1).
At this time, assemble the cylinder so that the orientation of the speed controller is opposite to
that of the stopper tip.
Additionally, assemble the cylinder so that the distance between the end face of the stopper
arm and the end face of the rod becomes that shown in the Figure below.
5) After the components have been reassembled, supply air (0.49 MPa) to check that the stopper
cylinder moves smoothly.
