CHAPTER 5
SEWING
CAUTION
• Do not touch moving parts (such as the knife,
needles and loopers) and adjustment parts (such
as dials and levers) during sewing.
• Do not open any cover during sewing.
• If any abnormality is noticed while using the
machine, immediately stop it, and contact your
authorized dealer.
Safety mechanism
This machine is equipped with a safety mechanism
in order to prevent misuse.
In the following cases, the red error indicator LED
lights up, and the machine does not operate.
• The front cover is open.
• The material plate cover is open.
• The presser foot lifting lever is raised.
Test-sewing
Turn on the machine and test-sew before you start
sewing.
1. Set all the thread tension to "4".
2. Thread the machine and pull all threads out
about 15 cm (6 inches) behind the presser
foot.
3. Place a piece of scrap material under the
presser foot for test-sewing.
NOTE:
Always lift the presser foot before placing the
fabric under it. You cannot start sewing by
just running the fabric under the presser foot
without lifting it.
4. Holding all threads with your left hand, turn
the handwheel slowly a few times toward you,
and check to see that the threads entwine
themselves before using the foot controller to
sew.
Chaining-off
After test-sewing, continue to depress the foot
controller slightly and chain off about 10 cm (4
inches). The threads will entwine themselves into
a chain automatically.
NOTE:
If the thread tension is not correctly balanced, the
chaining-off result will be uneven. If this happens,
pull the threads slightly. Check the threading and
adjust the thread tension to create an even chain.
(See "CHAPTER 1 Thread tension dial".)
