Caution:Do not disassemble nozzle shaft assemblies carelessly. Special equipment and skills are
required to remove and resemble a nozzle shaft. Such procedures should be attempted only
by maintenance staff who have attended training at Fuji and are equipped with the necessary
tools.
4 Move the turret slot for the removed nozzle shaft to between stations 8 and 9 at
0°, then turn on the solenoid (Y035 ST9 PLACE SOL ENGAGED).
5 With the cam angle at 0°, position the dial gauge as shown in the figure below.

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.
