Why haven’t I got the results I expected?
Very seldom does anything go wrong with this sewing
machine. It is well constructed and can withstand very
intensive use. Yes, generally it performs better the more
it is used. However, below you will find some advice if,
in spite of everything, you are not satisfied with your
sewing results.
Always start by checking the needle
An important part which needs to be changed from
time to time is the needle. Always start with a new
needle as soon as you discover that a seam is not what
you expected. Test sew on a scrap of the fabric you are
sewing. Read about needles on page 44.
Check that you have chosen the correct needle and see
that it is correctly inserted.
Unattractive stitches
The thread tension is not correct. See page 14.
The machine may be incorrectly threaded. The correct
threading is shown on page 12.
The needle, thread and fabric do not correspond. See
page 44.
Wrong upper thread. It should be of the same thick­
ness as the lower thread.
Bobbin wrongly inserted in the bobbin case. See page
12
.
The needle breaks
You may have helped the machine to feed by pulling
the fabric. The needle can easily strike against the needle
plate and break.
The upper thread breaks
Check the thread spool to see that it has not caught in
any way.
The needle eye may have sharp edges which cut the
thread. If so, change ¿le needle. See page 15.
The upper thread is incorrectly threaded. See page 12.
The upper thread may have too much tension. Refer to
thread tension, page 14.
The thread is knotted.
The thread and needle do not correspond. See page 44.
The hole in the needle plate may be chipped and have
sharp edges. SUght damage to the needle plate can pos­
sibly be polished or filed but we recommend that you
replace it. See page 39.
Lower thread breaks
The bobbin case is incorrectly inserted. See page 12.
The lower thread may be incorrectly threaded. See
page 12.
The needle plate hole is damaged. Slight damage to the
needle plate can possibly be polished or filed but we
recommend that you replace it. See page 39.
