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 【Confirmation of Pattern Shape】in the above sector.

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 thread, as well as needle-jumping, can be avoided in the high speed start. The thread-catching

function is only available when the Thread-catching Display LED is on. User can use turn on/off this function. When the thread-catching device is OFF, the machine will turn to

low-speed start automatically.

The thread-catching action will be invalid if the Storage Parameter No.35 is set as 1

Page 12

(Thread-catching Forbidden). At the same time, becomes invalid.

Matters for attention in using the function for catching upper thread

1． For catching thread, please shorten the upper thread at sewing start.

If the needle is too long, the thread at the backside of the cloth will be pulled out;

meanwhile that too-long needle will easily sew the end of the thread on needle into the seam.

1） The standard length of needle thread in thread-catching shall be 33～36mm. 2） Lengthen the thread after replacing the needle thread. Or when holding the needle

thread at sewing, please set the Thread-catching Key at OFF.

3） When the needle thread held with the thread catcher is rolled in the seams, do not

draw the material forcibly but cut the connecting needle thread with the scissors or the like. The seams are not damaged since it is the needle thread at the sewing start

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

3.3 Recovery to Default Setting

If the user changes some parameters by mistake, which are properly set at delivery, he will

use the function of “Recovery to Default Setting” to restore the system.

Note：At recovering the default settings, the entire parameters that are set by user

before will be covered. Therefore, please take caution in using this function. For anything unknown, please contact the technicians of the manufacturer, and operate the machine with the instruction from the professionals

The following is the specific operation step：

1、 When the Sewing LED is off, operator can press

and then the operator needs to press buzzer, the modification of service parameters is started.

2、 By using the & , the operator can select the parameter No.67：

to have system display ,

together. Following the voice from

3、Press

& ：

to turn the sewing LED, then select the needed software version number by using

Page 40

4、For an example, if the existing version is 2, operator can restore it to 0 or 1 (smaller than the

current version number in all). And then press

to confirm the restored version number

and turn off the Sewing LED；

1、 Press

to quit the setting mode of service parameters. Then the system will return to the

normal sewing mode;

2、 And then, turn off the power and repower the machine after about one minute. At the moment,

“EEP——” will be displayed on the operation panel. After 20 seconds, the operation panel will become to display normally (attention: it is a normal phenomenon because the system needs some time to perform the recovery of the default software).

3、 After the recovery, the system will set the current software version as the highest version. For

example, there are 2 default versions, Version 1 & Version 0; in that case the version after the recovery will be defined at 2 automatically.

Page 41

Attention: During the process of repowering the machine, if the power is off when the system is recovering, the recovery will be failed and the system will return to the software status before the recovery.
