6-3. Using the lower thread counter
• The lower thread counter can be used to let you know approximately how much lower thread is remaining.
• The value displayed by the lower thread counter display is reduced by 1 from the initial setting value each time the sewing
machine sews 10 stitches, and a warning is given when the counter reaches “-1”.
<Initial value setting>

will show the initial value which was set previously.

• When the key is pressed, the setting increases.
• When the key is pressed, the setting decreases.
• If you hold down the keys, the setting will change more quickly.
• If a value of “0” is set, the lower thread counter will not operate.
• The initial setting value will be accepted when sewing starts.
<Lower thread counter operation>
1. When sewing is carried out, the value shown in the lower thread counter display is reduced by 1 for every 10 stitches
sewn.
(After the value reaches zero “0”, a minus sign appears and counting continues to a maximum of “-999”.)
2. When the value is “0” or less, a warning icon (1) illuminates and an electronic buzzer sounds for 10 seconds.
3. Sewing can continue until the treadle is depressed backward, even if the value becomes “0” or less. (After the treadle is
depressed backward, the sewing machine will not operate even when the treadle is depressed forward again.)
• When the RESET key (2) is pressed, the warning icon (1) will switch off and the display will return to the initial value.
Sewing can then be carried out using the treadle.
• Use the keys to change the initial value.
* If you would like to return the lower thread counter display to the initial value before it has reached “0” or less, press
the RESET key (2) for 2 seconds or more.
