Threading, thread tension
Threading the lower thread
When the bobbin winding is finished, place the bobbin
beside its case with the marking upward. The thread
should run as shown in the figure. Place the bobbin in its
case without turning it around.
Slide the thread into the slot on the edge of the bobbin
case. Pull the thread in under the tension spring. Check
that the bobbin rotates in the direction of the arrow
(clockwise) when the thread is pulled.
The thread must be pulled in the direction of the
spring, otherwise the spring will be overloaded.
Insertion of the bobbin case
Slide the thread behind the projection of the bobbin
case and to the right. Put the bobbin case into place.
Press the bobbin case until it clicks to ensure that it fits
properly.
The thread cutter is located to the left of the bobbin
case. Hold the thread end and draw the thread from
underneath and up toward the thread cutter. By doing so
the thread will be cut off and kept in place.
Shut the door.
Threading the upper thread
Raise the presser foot. Check that the needle is at its
highest position. Place the spool of thread on the left
spool pin 1 and thread the machine for sewing.
Slide the thread into thread guide 2 on the upper arm
and draw it upward. Then draw the thread to the front
between the tension discs 3 and down around thread
guide 4. Continue threading by drawing the thread from
the right into the slot on thread take-up lever 5 and draw
it down to the needle, ensuring that it goes through
thread guide 6.
Thread the needle from the front. Due to the white
color of the presser foot ankle the needle-eye is clearly
seen and the threading of the needle, 7, is easier. Pull the
thread under the presser foot about 15 cm (6") toward
the rear.
