Thread the upper thread correctly as shown in the
illustration.
1) When pulling the thread out from the zigzag
thread tension (1), move the tension release lever
(2) in the direction of the arrow to open the
tension discs (3) in order to make it easier to pull
out the thread.
2) After threading the arm thread guide (4), pass the
thread under the thread guide (5) as shown in the
illustration to make it easier to thread.
3) Push the needle bar to the right to make it easier
to pass the thread through the needle.
NOTE:
The thread tension (6) is used to prevent the upper
thread from becoming knotted, tangled or loose, so
do not touch it. It is tightened only gently. If it is
tightened too firmly, the knob may become dam-
aged.
