The hook thread is normally wound on when sewing is in prog-
ress. However, you can also wind on the hook thread without
sewing, e.g. if you require a full bobbin in order to start sewing.
Winding procedure
1. Switch on the sewing machine.
2. Press the foot pedal forwards.
The machine sews and winds the hook thread from the
thread reel onto the bobbin.
When the bobbin is full, the machine automatically stops
winding. The bobbin lever moves down.
The cutter is automatically moved into its basic vertical
position.
3. Pull off the full bobbin.
4. Tear off the thread behind the cutter.
5. Insert the full bobbin in the hook
( Replacing the hook thread bobbin, p. 34).
6. Repeat the winding-on procedure with an empty bobbin, as
described above.
Damage to the sewing feet or needle plate possible if the
thread is wound on without material.
Lock the top roller in place in the highest position.
