< The relation between the respective machine heads and the positions of installing hole of the
bracket are as described in the table. >
The screws supplied with the machine as the accessories are for LH-3100. When they are used for
other machine heads, there is a possibility that the screw hole is crushed.
Do not use the screws supplied with the machine as the accessories with the machines other than
LH-3100.
When installing the control panel on DDL-8700, the machine with AK device is different from that

!0 Thread trimming prohibition switch
• Used for prohibiting thread trimming at any occasion.
!1
Bobbin thread counter/thread trimming counter
• Bobbin thread counter/thread trimming counter
can be changed over by the function of the control
box main body.
Bobbin thread counter :
• Indicates the amount of bobbin thread while
counting it by subtracting from the set value.
• When the bobbin thread remaining amount
detecting device is installed on the machine, the
counter indicates the number of times of detecting.
Thread trimming counter :
• Every time thread trimming is performed, the
counter value is added.
!2 Bobbin counter reset switch
• Used for returning the value shown on the

• Pressing the needle up/down compensation
switch, turn ON the power to the machine, and
the needle bar stop position when the pedal is
in its neutral position is changed over to down
position/up position.
• Conrmation of the stop position can be
performed at the front cover of the control box.
When up position stop is specied : " nP UP "
When down stop position is specied : " nP Lo "
!5 Function setting switch
• Pressing the function setting switch, turn ON

The range of the number of stitches that can be
changed : 0 to 19 stitches
4) Four different stitching patterns can be
performed by matching the ON and OFF settings
of automatic reverse stitching (for start) switch 2
and automatic reverse stitching (for end) switch
3.
5) Furthermore, the double reverse stitching can be
selected by operating double reverse stitching
(for start) switch 5and double reverse stitching

(2) Constant-dimension stitching pattern
1) Press constant-dimension stitching pattern
switch 1on 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 5
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 4for setting the
number of stitches for processes A and B.
Adjusting range : A, B = to 19 stitches
C, D = 5 to 500 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 2and automatic reverse stitching (for end)
switch 3.
5) Furthermore, the double reverse stitching mode can be specied by operating double reverse stitching (for
start) switch 7and double reverse stitching (for end) switch 8.
6) If automatic thread trimming switch 6is turned ON, the sewing machine will automatically perform
thread trimming after it nishes 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 nishes the automatic reverse stitching (for end) even when the automatic thread
trimming switch is not selected.)
If automatic thread trimming switch 6is 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 9is chosen, the machine will stop with the needle up without
performing thread trimming.
8) If one-shot automatic stitching function !0 is chosen, the machine will automatically perform sewing at a
stretch, at the specied speed by depressing the front part of the pedal.

settings of automatic reverse stitching (for start) switch 2and automatic reverse stitching (for end) switch 3.
5) Furthermore, the double reverse stitching mode can be specied by operating double reverse stitching (for
start) switch 6and double reverse stitching (for end) switch 7.
At each step the sewing machine automatically stops after sewing the predetermined number of stitches.
At this time, if the touch-back switch is operated, the sewing machine runs at a low speed (stitch
compensation operation). Also, at the last process, 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.
6) If automatic thread trimming switch 8is 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 nishes the automatic reverse
