SINGER W8910 - Manual (Page 55)

Fault-finding
Why haven’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 page 13 for
correct thread tension.
The machine does not feed the fabric
The stitch length is too short. Press the + button.
The feed teeth may be lowered. Raise them by
pressing the feed teeth button. See page 9.
The presser foot pressure is disengaged. See page 9.
The feed teeth are full of dust and dirt. Clean with the
brush. See page 51.
The seam is too loose—fabric layers not held together
The thread tension is far too loose. Pages 12—13 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
feed teeth. See page 51.
Dirt or lint has fastened in the hook. Remove the
bobbin and bobbin case and clean with the brush. See
page 51.
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.
*1
If the machine does not sew the pattern indicated by
the symbol, it is possible that the electronics have been
disturbed in some way, perhaps by a short power cut or
electrical disturbance. Shut off the main switch, w'ait a
few seconds and try again. If the fault remains, contact
your dealer.
