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.

5-7. Replacing the Support Table Home Position Sensor
(BU Home Position Sensor)
1) Detach the sensor from the sensor bracket.
2) Adjust the distance between the sensor and sensor dog to 1 mm.

5-8. Replacing the T-PIN Sensor (Optional)
1) Remove the adjustment screw to detach the sensor bracket and replace the sensor.
When reassembling the components, adjust the position of the sensor bracket by loosening the
adjustment screw and moving the sensor bracket up and down so that the T-PIN sensor is
turned ON when the center ring pin is lowered by 1.5
0
-0.5
mm.
2) Carefully handle the cables.

5-9. Replacing the Pusher Y Cylinder (Outer Shape Reference)
1) Remove the parts c to detach the cylinder. As the cylinder is detached,
the spring is also then removed.
2) Detach the speed controller from the cylinder. (At this time, check what
side the speed controller has been mounted.)
3) With the cylinder rod secured with a spanner, remove the part d with
another spanner.
4) Reassemble the components in the order of steps 3) to 1).
5) After the cylinder components have been assembled, supply the air
(0.49 MPa) to check that the cylinder moves smoothly.
∗ The cylinder mounting direction of the front reference machine is different from that of the rear
reference machine.
∗ For the rear reference machine, secure the speed controller with a tie-up band so that it does not
interfere with the width adjustment timing belt when the PWB width is set at its maximum level.
∗ The speed controller of the cylinder has been adjusted (page 5-9 in QA Table). No adjustment is
needed even after replacement of the parts.
