PREFACE
This Engineer’s Manual is written for the technical personnel who are responsible for the service and maintenance
of the machine.
The Instruction Manual for these machines intended for the maintenance personnel and operators at an apparel
factory contains operating instructions in detail.
It is advisable to use the Instruction Manual and Parts List for CP-18,CP-180 and Machine heads together with
this Engineer’s Manual when carrying out the maintenance of these machines.
This manual gives the “Standard Adjustment” on the former section under which the most basic adjustment value
is described and on the latter section the “Results of Improper Adjustment” under which stitching errors and
troubles arising from mechanical failures and “How To Adjust” are described.

4. Four different kinds of stitching patterns can be performed according to the combination of ON/OFF settings of
automatic reverse stitching (for start) switch and automatic reverse stitching (for end) switch .
5. Furthermore, the double reverse stitching mode can be specified by operating double reverse stitching (for start)
switch and double reverse stitching (for end) switch .
6. If automatic thread trimming switch is turned ON, the sewing machine will automatically perform thread
trimming after it finishes the predetermined number of stitches between C and D. (If the automatic reverse feed
stitching (for end) is selected, the sewing machine will automatically perform thread trimming after it finishes the
automatic reverse stitching (for end) even when the automatic thread trimming switch is not selected.)
If automatic thread trimming switch is turned OFF, operate the touch-back switch after the completion of
processes C and D. Then the machine runs at a low speed (stitch compensation operation).
Also, if the pedal is returned to its neutral position and depressed its front part again, the sewing can be continued
regardless of the setting of number of stitches.
7. If thread trimming prohibiting function is chosen, the machine will stop with the needle up without performing
thread trimming.
8. If one-shot automatic stitching function is chosen, the machine will automatically perform sewing at a stretch,
at the specified speed by depressing the front part of the pedal.
1. Press constant-dimension stitching pattern
switch on the control panel to select the
constant-dimension stitching pattern.
2. The constant-dimension stitching pattern is
selected. Now, the predetermined number of
stitches and the state of reverse stitching
function are shown on the control panel.
3. To change the number of stitches of the
processes in the constant-dimension stitching
pattern, change the number of stitches for
processes C and D by operating switches
for setting the number of stitches for processes
C and D. Select the reverse feed stitching
accordingly. To change the number of reverse-
feed stitches, operate switches for setting
the number of stitches for processes A and B.

sewing machine will repeat the normal stitching
and reverse stitching by the predetermined times.
Then, the sewing machine will automatically
make the thread trimmer actuate and will stop to
complete the overlapped stitching procedure.
(The one-shot automatic stitching cannot be
turned OFF.)

are shown on the control panel.
3. To change the number of stitches of the processes in the rectangular stitching pattern, operate switches (for
processes C and D) to change the number of stitches for processes C and D.
Select the reverse feed stitching accordingly. To change the number of reverse-feed stitches, operate switches
for setting the number of stitches for processes A and B.
(Adjustable range : A, B = 0 to 19 stitches, C, D = 0 to 99 stitches)
4. Four different kinds of stitching patterns can be performed according to the combination of ON/OFF settings of
automatic reverse stitching (for start) switch and automatic reverse stitching (for end) switch .
5. Furthermore, the double reverse stitching mode can be specified by operating double reverse stitching (for start)
switch and double reverse stitching (for end) switch .
When the touchback switch is operated at this time, the sewing machine runs at a low speed (compensating
stitching). In the final step, sewing can be continued regardless of the setting of the number of switches when the
pedal is returned to its neutral position and its front part is depressed again.
6. If automatic thread trimming switch is turned ON, the sewing machine will automatically perform thread trimming
after the completion of the last process. (If the automatic reverse stitching (for end) is selected, the sewing machine
will automatically perform thread trimming after it finishes the automatic reverse stitching (for end).)
7. If thread trimming prohibiting function is chosen, the machine will stop with the needle up without performing
thread trimming.
8. If one-shot automatic stitching function is chosen, the machine will automatically perform sewing at a stretch
until the number of stitches specified is reached, at the predetermined sewing speed by depressing the pedal
while the sewing machine is engaged in the sewing of process C or D. The machine performs thread trimming in
the last process of one-shot automatic stitching pattern.
9. For the sewing machine equipped with an auto-lifter, the presser foot will automatically go up after the completion
of each sewing process.

(5) Example of application
1) When the CP-180 is used together with the material end sensor it can be used as a small edge-controller.
(Method) Adjust the position to mark of the CP-180, turn ON material end sensor ON/OFF switch of the
turn ON mark of the automatic one-shot stitching.
(Caution) Number of rotations of the automatic one-shot stitching can be changed by the function set-
ting (No. 38).

2) Label attaching is performed by the automatic one-shot stitching with the CP-180
(Method) Select mark on the CP-180, and turn ON mark of the automatic one-shot stitching.
Label
CD
CD
(Explanation) Number of stitches at the section CD can be set up to 500 stitches. If the stitch length is 2 mm, it is
possible to sew approximately 1,000 mm (1 m).
This function can perform the automatic one-shot stitching without using the material end sensor.
Therefore, the sewing machine performs the sewing to the last according to the sewing pattern
even if the label is not located at the end of material when the pedal is depressed once.

3) Seam joining of the reverse feed stitching at the end of sewing (For thick materials)
Especially some sewing machine heads for thick materials are likely to fail joining the seam at the section of the
following figure even if the timing of reverse feed stitching at the end of sewing is compensated.
1At the timing to move to the reverse feed stitching action,
the rotating speed at the section where the sewing machine
is rotated at a low speed can be changed.

WARNING :
•To prevent personal injury caused by abrupt start of the sewing machine, carry out the work after turning OFF the
power switch and a lapse of 5 minutes or more.
•To prevent damage of device caused by maloperation and wrong specifications, be sure to connect all the corre-
sponding connectors to the specified places. (If any of the connectors is inserted into a wrong connector, not only
the device corresponding to the connector can break but also it can start abruptly, inviting the risk of personal
injury.)
•To prevent personal injury caused by maloperation, be sure to lock the connector with lock.
• As for the details of handling respective devices, read carefully the Instruction Manuals supplied
