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. (Subtraction is made according to the setting of function
setting No. 7, bobbin thread count down unit.) 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 facto-
ry-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 change-
over speed is increased.
10. 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 re-
placed, press bobbin thread counter reset switch
1to return the value on the bobbin thread coun-
ter to the initial value. Now, re-start the sewing
machine.
6) If the remaining amount of bobbin thread is ex-
cessive 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.

12. NEEDLE UP/DOWN COMPENSATION SWITCH
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.
Whenever pressing the needle up/down
compensation switch 1and turning ON the power to
the machine, the stop position when the pedal is in
its neutral position can be changed over.
Als o , t he specified s t a te at this time can b e
conrmed at the panel.
(The contents shown there will be reflected 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).)
