Fault-finding________________________
Why havent’t I got the results I expected? (cont.)
Uneven thread tension
This may be due to poor quality thread.
Irregular bobbin winding
The bobbin is not placed correctly. See page 11.
The machine is not correctly threaded for bobbin
winding. See page 11.
The fabric puckers
The upper thread tension is too tight. See pages 13-14
for correct thread tension.
The machine does not feed the fabric
The stitch length is too short. Turn the stitch length
dial to a higher number.
The feed dog may be lowered. Raise it by pressing the
lower part of the feed dog button. See page 11.
The presser foot pressure is disengaged. See page 10.
The feed dog is full of dust and dirt. Clean with the
brush. See page 39.
The seam is too loose — fabric layers not held together
The thread tension is far too loose. Pages 13-14 show
how to adjust the thread tension.
Machine runs sluggishly
Dirt or lint has fastened under the needle plate.
Loosen the needle plate and brush clean between the
teeth of the feed dog. See page 39.
Dirt or lint has fastened in the hook. Remove the
bobbin case and clean with the brush. See page 39.
Expert assistance
If you have followed the preceding points and still do
not get satisfactory results, you should contact your
dealer.
He will always be more than willing to give you advice
and help as to what measures should be taken.
When the machine is being checked, it is a great help if
it can be test sewn under as similar conditions as possible
as when you used it.
Remember to take a sewing sample along with you,
preferably on the fabric and with the thread you intend
to use.
A sewing sample will often give much better informa­
tion than words.
