Exchanging the needle
1 Pull the plug from the wall socket.
2 Turn the flywheel until the needle is in its highest position.
3 Turn the needle clamp loose as shown in the picture. (illustration 6)
4 Take the needle from the needle holder.
5 Insert a new needle.
6 Then screw the needle clamp as tight as possible.
Check the needles at regular intervals. The needle must be straight and sharp as is shown in
pictures a and b. Do not use any needles that are bent or blunt, as in pictures c, d, e or f.
(illustration 7)
Removing and placing the pressure foot
(illustration 8, 9 & 10)
1 Turn the wheel until the needle is at its highest position. Lift the pressure foot up by
moving the pressure foot lever upwards.
2 By pressing the foot interlocking the sewing foot automatically falls from its holder.
3 Insert the foot under the holder in such a way that the pen of the foot is under the notch in
the holder. By then taking the pressure foot lever down and pressing the foot interlocking,
the foot automatically clicks into its holder.
Controlling the thread tension
(illustration 11)
1 The upper thread and the bobbin thread must interlace with each other in the middle of
the two layers of material.
2 If the top thread tension is too low (this is visible when the interlacing is at the bottom of
the two layers of material), you can raise this by turning down the top tension control
button (1 > 9).
3 When the top thread tension is too high (this is visible if the interlacing is at the top of the
two layers of material), you lower this by turning the top tension control button upwards
(9 > 1).
Controlling the bobbin thread tension
(illustration 12)
If you do not succeed in controlling the top thread tension to get the interlacing in the right
position, you can try this by adjusting the bottom thread tension. To increase the tension, you
turn the tension screw in the direction as indicated in the picture.
To lower the tension you turn the tension screw in the opposite direction.
To check the tension you take the thread as indicated in the picture, now the bobbin housing
must drop down 3 to 4cm. (illustration 13)
To get a fine zigzag stitch the top tension must be set a little slacker than with a straight lock
stitch. The needle thread must be slightly visible at the bottom of the material.
Stitch length control
(illustration 14)
1 The numbers on the stitch length selection button approximately correspond with the
stitch length in mm.
2 You can select the desired stitch length with this button. In the picture this is set to a stitch
length of 2 mm.
3 When sewing extensible seams you set the stitch length to SS (stretch stitch).
