2.2.3 Sewing
1． Put the fabric to the presser section
2． Step on the pedal switch to the level 1, then the
presser goes down. If you detach the foot from the
pedal, the presser will go up.
3． Lower the presser to the next level, and then
depress the pedal to the second level to start sewing
4． At sewing end, the presser will go up and stop at
the initial position.
Attention 1：When depressing the pedal to level 1 and lowering the presser, the user can
press & to change the sewing position of pattern. Then the user could start sewing
at the selected position by depressing the pedal to level 2. During the sewing, for the problems like
thread-breakage, user can use this method for mending after releasing the malfunction
Attention 2： Don’t apply the operations in Attention 1 into the operation of pattern trial sewing,
in case the user depresses the pedal to level 2 by mistake, thus start the machine and cause the
dangerous. For the operations in trial sewing, user shall strictly follow the descriptions of

become valid.
Independent thread-trimming, different from the general presser transmission and main-shaft
transmission thread-trimming mechanisms, has the independent control unit, which can control the
whole process of thread-trimming better,
If the storage parameter No.35 is set as 1 (Thread-trimming Forbidden), the machine will not
perform the thread-trimming.
2.2.7 Thread-catching Device
With thread-catching device, the abnormal sewing, like the missing or staining of upper

.
2. In order to make thread-catching action ensure the stable sewing at start, user can shorten
the needle so that less needle thread could be winded in upper side of the cloth.
3. When the type of lower plate (1) that material doesn’t closely contact to the board (2) is
used, needle thread at backside of cloth will be rolled into the seams regardless the length
of the thread or the needle thread will be loose
