Trouble Shooting; The Needle Breaks; The Upper Thread Breaks; The Fabric Puckers - Husqvarna Viking Viking Iris User Manual

Trouble shooting
Always start by checking the
needle
Always start with a new needle as
soon as you discover that a stitch is
not what you expected. Test sew on
a scrap of the fabric you are sewing.
Check that you have chosen the
correct needle and see that it is
correctly inserted. See page 15.
Unattractive stitches
The thread tension is not correct.
See page 13. Make sure that the
thread is not catching. Certain thread
spools are unsuitable for spooling
from the horizontal spool pin. Try
instead with the vertical spool pin.
The machine may be incorrectly
threaded. Be sure to place spool
holders correctly.
The correct threading is shown on
page 9.
Wrong bobbin thread. It should be
of the same thickness as the upper
thread except when sewing
embroidery.
The needle breaks
The needle can strike against stitch
plate and break. Change the needle.
See page 15.
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 the needle. See page 15.
The upper thread is incorrectly
threaded. See page 9.
The upper thread may have too
much tension. Refer to page 13.
The hole in the stitch plate may be
chipped and have sharp edges. We
recommend that you replace
it.
The bobbin thread breaks
The bobbin thread may be
incorrectly threaded. See page 12.
The stitch plate hole is damaged.
See "Upper thread breaks".
Irregular thread tension
This may be due to poor quality
thread. When sewing with cotton
thread, increase the thread tension.
See page 12.
Irregular bobbin winding
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.
Use the correct presser foot as
recommended by the infodisplay.
The machine does not feed the
fabric
The stitch length is too short.
Increase stitch length.
The feed teeth may be lowered.
Raise them by turning the dial to
-—-.
See page 15.
The feed teeth are full of dust and
dirt. Clean
with the brush. See page
47.
