6 The vertical difference between the base of the slider and the cut out section in
the cylindrical cam should be ±0.02 mm. If necessary, loosen the locknut in the
cambox and adjust the length of the rod.
7 Reattach the nozzle shaft assembly in the original location.
Using the clutch alignment jig, reverse the removal procedures to attach the
assembly.
Caution:The nozzle shaft assembly is exclusive to the CP-842E/842ME, and cannot be used on
other machine types, such as CP-733E, CP-743ME, or CP-743E.

Adjusting the Nozzle UP Limit Sensors
The nozzle UP limit sensor that detects the up limit position of the nozzle UP/DOWN
rod at station 9 is mounted inside the cam box. Adjust the position of this sensor so
that it switches ON when the nozzle is at its UP limit position.
1 Press the EMERGENCY STOP button to take the 200V down to 100V.
2 Set the cam axis at 0°.
3 Activate the ST9 placing solenoid air cylinder (located in the cam box):
Execute the following I/O commands: [Maintenance] - [I/O Check] - [Standard I/
O] - [Y035 ST9 PLACE SOL ENGAGED] - [Output Signal ON]
The cam lever will then follow the cam.
WARNING
• Press EMERGENCY STOP before performing this procedure.
• Exercise extreme caution when working on the machine if the cam
is not at its origin (0 deg.). Spring recoil can rotate the cam inde-
pendently.

4 Place a dial gauge on the top end of the cam lever and zero the gauge. In this
condition, the cam axis will be at its 0° position, and the nozzle UP/DOWN rod
will be at its UP limit position. Verify that the nozzle UP limit sensor is ON
(X032 ST9 CYLINDER UPPER LIMIT is ON).
5 While observing the dial gauge, advance the cam to lower the nozzle UP/DOWN
rod. Adjust the sensor position so that the sensor switches OFF (X032 ST9
CYLINDER UPPER-LIMIT) when the rod is lowered 0.3 to 0.4 mm.
Adjust the sensor position by loosening the sensor lock screw and sliding the
sensor forward or backward.
