The number of stitches sewn by the sewing machine is detected. The detected number of stitches is dec-
remented from the preset counter value (in units of the number of stitches preset using function setting No.
7 "Unit of bobbin thread counting down"). When the counter value changes from the positive value to the
negative value (...→ 1 → 0 → -1), the buzzer sounds (3 sets of two consecutive blips) and the notication is
shown on the pop-up window to alert the operator to change the bobbin.

ing. In this case, make the thread trimmer actuate once.
❶
2) Set an initial value using counter value setting switches
.
❺
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
on the left side.

* The aforementioned values actually vary depending on the
material thickness and sewing speed. Adjustment is necessary
according to the conditions of use.
❹
and
3) Once the initial value is specied, start the sewing machine.
4) When a minus value is shown on the counter, the buzzer peeps three times and the pop-up display ap-
pears, replace the bobbin thread.
Bobbin thread replacement warning pop-up
5) After the bobbin thread has been properly replaced, press counter reset switch
to return the value on
❸
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 counter value setting
switches ❹ and ❺.
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 “–” switch.
The remaining amount of thread may vary depending on how the thread is wound on the bobbin and the material thickness. It is therefore better to set the remaining amount of thread with a slight allow­ance.
