Troubleshooting
Handy Tips
1.
Always start to sew with the needle
lowered into the fabric and the
presser foot lever down.
2.
To change direction: stop sewing,
ensure needle is lowered into your
fabric, raise the presser foot lever, turn
fabric, lower presser foot and start
sewing again.
3.
Only use bobbins similar to those
supplied with the machine – bobbins
vary greatly so always take one with
you to the shop when purchasing
new ones.
4.
Needles blunt very easily so remember
to change regularly.
straight from the scrap to your own
fabric. This prevents puckering at the
edge of your seam. Just cut off the
scrap when you have finished sewing.
10.
If any problems occur, always try
rethreading the machine first. Also try
rethreading the bobbins as
sometimes thread winds on unevenly.
11.
Clean out any dust or fluff from the
bobbin case regularly using a small
brush such as a paint brush.
5.
Always test your machine on scrap
fabric before commencing sewing
especially if the machine has not been
in use for awhile.
6.
Store in a clean dry place, out of direct
sunlight preferably in its box or similar
to avoid dust. Keep away from direct
heat.
7.
Always unplug after use.
8.
Do not allow to get wet.

When beginning to sew at the edge of
fabric it is recommended that a small
scrap of fabric is used to start sewing
on as shown in the diagram. Sew
