4-5. Threading the upper thread 
     CAUTION 
 
Turn off the power switch before threading the upper thread.   
The machine may operate if the treadle is depressed by mistake, which could result in injury. 
Turn the machine pulley and raise the thread take-up (1) 
before threading the upper thread.   
This will make threading easier and it will prevent the thread 
from coming out at the sewing start. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
4-6. Adjusting the stitch length 
1.  Push the dial lock lever (1) up until it clicks to release the 
lock. 
2. Turn the stitch length dial (2) clockwise or counter-
clockwise so that the desired stitch length is at the upper-
most position on the dial. 
y The larger the number, the longer the stitch length will 
be. 
(The numbers on the dial are for use as a guide. The 
length of the finished stitches may vary depending on 
the type and thickness of material being sewn. Adjust 
while looking at the finished stitches.) 
y When turning the stitch length dial (2) from a larger 
setting to a smaller setting, it will be easier to turn the 
dial if the reverse lever (3) is pushed to the halfway-
down position. 
3.  Push the dial lock lever (1) down firmly to lock it. 
*  Check that the stitch length dial (2) does not rotate.

5. USING THE OPERATION PANEL   
(BASIC OPERATIONS) 
5-1. Names and functions 
• The operation panel keys cannot be operated while sewing is in progress. 
Select the keys and set the number of stitches before starting sewing. 
• In the case of keys with indicators, the indicator illuminates when that function is operating, and the indicator switches off 
when the key is pressed once more. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The power indicator illuminates when the power is turned on. 
(1) Main display 
 
 
 
 
 
 
 
 • In start backtack display, AB illuminates and the number of stitches for A and B are 
displayed. 
• In end backtack display, CD illuminates and the number of stitches for C and D are 
displayed. 
• In continuous backtack display, ABCD illuminates and the number of stitches for A, B, C 
and D are displayed. 
• In fixed stitch display, E or F illuminates and the number of stitches for E or F are 
displayed. 
 
(2) Setting keys 
  
 
 
 These keys are used to set the number of backtack stitches for A, B, C and D and the 
number of fixed stitches for E and F. 
• When the      key is pressed, the setting increases from 0 up to 99. 
• When the      key is pressed, the setting decreases from 99 down to 0. 
 
(3) Start backtack key 
  
 
 When this key is pressed so that the indicator illuminates, the number of start backtack 
stitches (0−99) in the A and B stitch number displays is sewn. 
(4)  End backtack key 
  
 
 
 
 When this key is pressed so that the indicator illuminates, the number of end backtack 
stitches (0−99) in the C and D stitch number displays is sewn. When the treadle is 
depressed backward, the end backtack stitches are sewn and then the thread is trimmed 
automatically. 
The number of stitches can be changed or deleted before the treadle is depressed 
backward. 
 
(5) Continuous backtack key 
  
 
 
 When this key is pressed so that the indicator illuminates, the number of backtack stitches 
(0−99) in the A, B, C and D stitch number displays is sewn continuously. After the sewing 
machine sews a full cycle of stitches set by A, B, C and D, the thread is trimmed 
automatically.

depressed backward. 
• If the indicator of the thread trimming key (9) is illuminated, the sewing machine stops in 
the needle up position without thread trimming being carried out after the set number of 
stitches have been sewn. 
 
(14)  Half stitch key 
  
 
 When the sewing machine is stopped, the needle bar can be moved up and down by 
pressing this key. 
(15)  Lower thread counter display

5-6. Using the lower thread counter 
y The lower thread counter can be used to let you know approximately how much lower thread is remaining. 
y 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 “-5”. 
 
 
1  
 
 
 
 
 
 
 
 
 
 
(Press for 2 seconds or more) After about 2 seconds, the buzzer will sound and the lower thread counter display

 y When the   key is pressed, the setting increases. 
y When the 
  key is pressed, the setting decreases. 
y If you hold down the keys, the setting will change more quickly. 
y If a value of “0” is set, the lower thread counter will not operate. 
y The initial setting value will be accepted when sewing starts. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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 “-5” or less, a warning icon (1) illuminates and an electronic buzzer sounds for 5 seconds. 
3.  After the treadle returns to the neutral position and the sewing machine stops, the sewing machine will not start up again 
even if the treadle is depressed. However, thread trimming can be carried out by depressing the treadle backward. 
  
y If you press the RESET key (2), the warning icon (1) will disappear and sewing will be possible when the treadle is 
depressed. 
y If you press and hold the RESET key (2) for 2 seconds or more, the display will return to the initial value.

(220 rpm) can be carried out. 
When the machine is stopped, stitches can be sewn one at a time by pressing the 
actuator. 
NOTE: 
• If you press the actuator while sewing is in progress, backtack stitches will be 
sewn. 
• Correction sewing cannot be carried out while the indicator of the pleat presser 
sewing key (8) is illuminated. 
• If you press this key again while the icon (21) is illuminated, the icon (21) will turn off. 
 
(22) Needle up/down key 
  
 
 
 
 Use this key to select whether the needle bar stops in the up position or the down position 
when the treadle is returned to the neutral position and sewing stops. 
• When the needle up icon 
  (23) is illuminated, the needle bar stops in the up position. 
• When the needle down icon 
  (24) is illuminated, the needle bar stops in the down 
position. 
 These are used for making advanced
operating settings. 
They should only be used by a technician.
