4.1 Detachment and Attachment of Nozzle Shaft (Single Unit)
4.1.1 Detachment of Nozzle Shaft (Single Unit)
When the two bolts (M1.6L3) are removed
as shown in Fig. E16, the nozzle shaft can
be disassembled from the cam follower.
Be sure not to drop the nozzle
shaft.
4.1.2 Attachment of Nozzle Shaft (Single Unit)
Assemble the cam follower section and the nozzle shaft with two bolts (M1.6L3).
• Tightening Torque: 720 gf/cm Screw Lock: 1401B
(a) The nozzle shaft and cam follower must be attached vertically as shown in Fig.
E18 without leaving any clearance between Face A of the cam follower and Face
B of the nozzle shaft.
(b) The nozzle shaft and the guide are regarded as an assembly (managed using the
same No.). Therefore, only the shaft or the guide cannot be replaced with a new
one.
4.1.3 Tightening Torque for Attachment of Cam Follower (Fig. E16)
• Use "LOCTITE" with tightening torque of 9.1 Ncm (900 gf/cm).

4.2 Detachment of Nozzle Shaft Assembly
4.2.1 Detachment of Large Diffusion Plate
(1) Remove the three screws (M1.6L5) of
the large diffusion plate (outer side).
Pay attention to the detachment
position. Pay attention to the
detachment position.
(2) Remove the two screws (M1.6L5) of the
small diffusion plate (inner side).
4.2.2 Detachment of Linear Measure Sensor (Fig. E20)
Remove the two screws (M1.6L5) of the linear measure sensor on the light emitting side
and detach the sensor from the motor side.
Do not detach the linear measure sensor on the light receiving side.
Disconnect the connector. (Fig. E21)
Springs are used at the lower area of the
nozzle shaft. Therefore, it is required to
attach a holding plate (drop prevention)
and detach the large diffusion plate in
the assembled condition.

4.2.3 Attachment of Nozzle Shaft Holding Jig
Attach the nozzle shaft holding jig to the area where the large diffusion plate was detached.
(Figs. E22 and E23)
(1) Attach the nozzle shaft holding
jig securely to the nozzle shaft
assembly (the position of the
large diffusion plate) with three
screws (M1.6L5).
(2) Connect the nozzle shaft
assembly with the motor
section.
Assemble the jig so that the
three screws (M1.6L5) can stay
visible.
