INSERTING THE BOBBIN
When inserting or removing the bobbin, the needle
must be fully raised.
Switch the power OFF
1 . Open the hinged cover.
2. Hold the bobbin case with one hand. Insert the bobbin so that the thread runs
in a clockwise direction (arrow).
3. Put the thread under the tension spring.
4. Hold the bobbin case by the hinged latch.
5. Insert it into the shuttle. Press it fully home and then release the latch.
CHECKING AND ADJUSTING THE BOBBIN TENSION
The bobbin tension is factory preset and should not need adjusting. However if the
tension is not correct the thread will not feed properly.
To test the bobbin thread tension:
Remove the bobbin case and bobbin and
hold it by suspending it by the thread. Jerk
it once or twice. If the tension is correct, the
thread will unwind by about 25-50 mm.
If the tension is too tight, it does not
unwind at all. If the tension is too loose,
it will drop too much. To adjust, turn the
small screw on the side of the bobbin case.
