Automatic thread trimmer

™ In case of thread trimming, the machine stops with its needle up after turning the amount equivalent to make one and a half stitches (when the machine has stopped

with its needle down) or two stitches (when the machine has stopped with its needle up). (115 rpm)

™ Make the machine perform steps 1 through 2 using the lateral feed STM, then the sewing machine drive motor will rotate and the thread trimmer will cut the needle

and bobbin threads.

- STM operation steps -

1 Disengage the drawing roller from the auxiliary roller.

First step

2 Disengage the knife.

Second step

3 The sewing machine runs at low speed (115 rpm), and the moving knife cuts the needle and bobbin threads.

4 Disengagement of the main shaft is released and the sewing machine stops with its needle up.

Thread trimming cannot be performed while the sewing machine is in rotation or is ready to stop.

Bobbin winding

1 Set the bobbin winder shaft lever to the bobbin winding position, and the sewing machine motor rotates by turning ON the bobbin winding switch, turning ON the S/

S SW, or depressing the controller. The main shaft is disengaged at the fixed position of the first rotation. The sewing machine is in the state of stopping with its

needle up and only the bobbin winder shaft rotates. (The hook driving shaft rotates.) (Upper limit 600 rpm)

2 While the bobbin winding switch is ON, the relevant message is shown on the display. In this state, any switch other than the S/S SW is not accepted.

Presser foot lift

When the presser foot is raised and S/S SW is turned ON, the relevant message is shown on the display.

Turning ON the S/S SW makes the machine rotate by the amount equivalent to make a half stitch or one stitch and stop with its needle up. At this time, the relevant

message appears on the display.

Press the pattern selector switch, and a group of patterns which corresponds to the switch pressed is shown on the pattern LCD.

If the number of patterns contained in the group is too large to display all of them at a time, the patterns on the LCD can be changed by operating the pattern selector

key, previous screen key or next screen key.
