3. Replacement of Doughnut Board
UB22
3.1 Detachment of Doughnut Board
(1) Detach the cover.
Remove the four bolts (M2L6) and detach the transparent cover. (Fig. E12)
(2) Disconnect Connectors CN1 through
CN12 (Change-Over Valves), CN13,
CN21, and CN22 from the doughnut
board. (Fig. E11)
Be careful not to make the
disconnected connectors
trapped by the frame while the
center shaft is rotating.
(3) Detach the four supports (M2) and
then the board from the motor section
as shown in Fig. E12.
(4) Disconnect the board from the connector sections into two halves as shown in Fig. E13
and take out the board.

3. Replacement of Doughnut Board
UB22
3.2 Attachment of Doughnut Board
(1) Put the doughnut boards (in the disconnected condition shown in Fig. E13) on the
DD motor and connect the connectors.
(2) Fix the board at the point where CN12 of the board is located just before the #1
nozzle and the dip switches are located slightly on the left side of the #1 nozzle when
the #1 nozzle is facing the front as shown in Fig. E11.
Apply "1401B" to the four M2 hexagonal supports for the fixation. (Fig. E14)
Confirm that no wires are trapped (pinched) and there is no interference between the
board and the frame when the motor section is rotated by hand.
(3) Connect Connectors CN1 through CN12 (Change-Over Valves), CN13, CN21, and
CN22 to the board as shown in Fig. E11.
Set the #1 and #5 dip switches to "ON".
(4) Attach the cover. (Fig. E14)
Apply "1401B" to the four bolts (M2L6).

4. Replacement of Nozzle Shaft
Nozzle Shaft
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).
