Trouble Shooting

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 page13. 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. For correct

threading, see page 9.

Wrong bobbin thread. It should be

of the same thickness as the upper

thread.

The needle breaks

The needle can strike against stitch

plate and break. Change the needle.

See page 15. Do not pull fabric as

you sew, let the machine feed.

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 incorrect-

ly 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.

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.

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

45.

The stitch is too loose - fabric

layers not held together

The thread tension is far too loose.

Page 13 shows how to adjust the

thread tension.
