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

The machine detects the number of stitches. The preset value on the bobbin thread counter is subtracted in
accordance with the number of stitches detected. (Every time the detector detects 10 stitches, 1 is subtracted from
the preset value on the bobbin thread counter.) When the value on the counter becomes a minus value as " 1 →0
→ -1 ", the buzzer peeps three times to warn the operator that the time to change the bobbin thread has come.
1) Press bobbin thread counter reset switch 1
to return the value indicated on bobbin thread
counter 2to the initial value (it has been factory-
set to "0" at the time of delivery).
The bobbin thread counter cannot be reset
during sewing. In this case, make the
thread trimmer actuate once.
2) Specify an initial value using bobbin thread
amount setting switch 3.
When keeping pressing the switch, the
changeover speed is increased.
6. HOW TO USE THE BOBBIN THREAD COUNTER
< Initial value on the bobbin thread counter for reference >
Thread used Length of thread wound
round the bobbin
Value on bobbin
thread counter
Polyester spun
thread #50 36m
1200 (stitch
length : 3 mm)
Cotton thread
#50 31m
1000 (stitch
length : 3 mm)
The table below gives the initial setting values for
reference when the bobbin is wound with thread
to the extent that the pinhole in the outside of the
bobbin case is reached as shown in the gure given
above.
※ Actually, the bobbin thread counter is affected
by the material thickness and the sewing speed.
So, adjust the initial value of the bobbin thread
counter in accordance with the operating conditions.
Thread tension rate 100 %
3) Once the initial value is specied properly, start
the sewing machine.
4) When a minus value is shown on the counter and the
buzzer peeps three times, replace the bobbin thread.
5) After the bobbin thread has been properly
replaced, press bobbin thread counter reset
switch 1to return the value on the bobbin
thread counter to the initial value. Now, re-start
the sewing machine.
6) If the remaining amount of bobbin thread is
excessive or the bobbin thread runs out before
the bobbin thread counter indicates a minus
value, adjust the initial value appropriately using
the “+” or “-“ switch of bobbin thread adjustment
switch 3.
If the remaining amount of bobbin thread is excessive
… Increase the initial value using the “+” switch.
If the remaining amount of bobbin thread is insufcient
… Decrease the initial value using the “-“ switch.
1. Uneven performance may occur in
accordance with the winding way of
thread or the thickness of materials and
it is necessary to set the thread trimming
amount with some surplus.
2. If the bobbin thread counter is used
in combination with the bobbin thread
remaining amount detecting device, the
bobbin thread counter indicates the number
of detections of the bobbin thread remaining
amount detecting device.
So, be sure to use the device after carefully
reading the Instruction Manual for the
bobbin thread remaining amount detecting
device.

Bobbin thread counter indication can be changed over to thread trimming counter (simplied sewing counter)
indication by the operation below.
1) Function setting No. 6 Turn OFF the setting of bobbin thread counter function. .
Function setting No. 6 0 : off / 1 : on
2) Function setting No. 14 Turn ON the setting of sewing counter function.
Function setting No. 14 0 : off / 1 : on
3) From turning ON the power next, the counter indication works as the thread trimming counter.
Every time thread trimming is performed, the counter indication is upped.
After selecting each item, be sure to perform updating of the function setting No.
When turning OFF the power without performing updating, the set contents are not changed.
For the updating procedure, refer to the function setting procedure described in the Instruction
Manual supplied with the control box.
4) When reset switch 1is pressed, the contents of indication 2will be reset to " 0 ".
5) When modifying the count value, increase/decrease the value with setting switch 3.

Every time needle up/down compensation switch
1
is pressed, the needle goes up when it is in its lowest
position or comes down when it is in its highest position.
This compensates the stitch by a half of the
predetermined stitch length
However, note that the machine does not run
continuously at a low speed even if you keep the switch
held pressed.
Also, note that the needle up/down compensation switch
is inoperative after turning the handwheel by hand.
Sewing of needle up/down compensation operation does
not make the thread trimming operation operative.
8. NEEDLE UP/DOWN COMPENSATION SWITCH
Whenever pressing the needle up/down compensation
switch
1
and turning ON the power to the machine, the
stop position when the pedal is in its neutral position can
be changed over.
Also, the specied state at this time can be conrmed at
the control box.
(The contents shown there will be reected when turning
ON the power after next time.)

• This switch is used, in the constant-dimension stitching mode, rectangular stitching mode, or in the
process where the material edge sensor is specied, to make the sewing machine automatically perform
sewing at the specied speed until the end of the process is reached only by driving the sewing machine
mode.
• When the material edge sensor, which is optionally available, is connected to the control panel, the ON/
OFF switch of the material edge sensor becomes effective.
• If the material edge sensor is specied, the sewing machine will automatically stop running or perform
thread trimming when the sensor detects the material edge.
• This switch is used to automatically actuate the thread trimmer in a process where the sewing machine
automatically stops or when the material edge sensor is used.
(If the automatic reverse stitching (for end) is specied, the thread trimmer will actuate after the sewing
machine completes the automatic reverse stitching (for end).)

11. AUTOMATIC THREAD TRIMMING SWITCH
12. ONE-SHOT AUTOMATIC STITCHING SWITCH
1) After the completion of the setting of data on the number of stitches, etc., turn OFF the power to the
machine once.
2) Turn ON the power switch while simultaneously pressing automatic reverse stitching (for end) switch 1
and the " + " switch of number of stitches setting switch 2 for process A with ngers.
3) Key mark 3is shown on the control panel. This completes the locking of keys.
(If the key mark is not shown on the control panel, carry out the aforementioned steps 1) through 3) again.)
* To release the keys from the locked state, perform again the steps 1) and 2).
(Once the key mark goes out, the keys are released from the locked state.)
In order to prevent the specied data on the number of stitches or the processes (A, B, C and D) to be
changed by mistake, the setting switch can be locked. (Even with the setting keys locked, the pattern to be
sewn and the value on the bobbin thread counter can be changed.)
9. KEY LOCK FUNCTION
If the material edge sensor is used in combination with the control panel, carefully read the
Instruction Manual for the material edge sensor beforehand.

・This switch is used to temporarily make the thread trimming function inoperative.
The other performance of sewing machine is not affected by this switch.
(If the automatic reverse stitching (for end) is specied, the sewing machine will perform the automatic
reverse stitching at the end of sewing.)
・If the automatic thread trimming switch and the thread trimming prohibition switch are both
specied, the machine will not perform thread trimming but stop with its needle up.
13. THREAD TRIMMING PROHIBITION SWITCH
1) Pressing function setting switch 1, turn ON the power to the machine.
2) The indication on the control panel is changed over to the function setting indication mode.
Function setting No. is shown at section Aand the set value is shown at section Bof counter indication
section.
※ The contents to be shown will be different according to the contents that were set in the last time.
3) Function setting No. can be changed over by operating switch 2.
4) Function set value (setting state in case of on/off) can be changed over by operating switch 3.
5) After completion of setting, the changed contents are stored in memory and reected from the next time.
