unnecessary to raise presser foot. when machine is bone only operator only need to pull with
hand before sewing, and it is absolutely unnecessary to raise presser foot. on the contrary,
stitch length is uneven and stitch trace is caused not beautiful if the presser foot is raised. on
this point we have to pay attention to adjust operator to change this bad operation habits .

Q:
material in a high speed.
Answer: this problem is in our consideration, and the machine has been set three
different presser foot height, respectively 5mm
、
9mm and 12mm,and the The factory
standard height is 9 mm. User can change the most height only if open machine rear cover
plate, and change the fixed screw position on the presser rod.
11.Q:How to adjust the presser foot higher , but not too high?
Answer: what you need can’t be meet due to the Electromagnet presser foot used in this
machine. The pattern control you want can be realized, but the control cost will be expensive.
our corporate mission is“Provide sewing machinery with the best cost-performance ratio to
all”. As to the function of presser foot, the way of controlling Electromagnet can meet user’s
need basically, meanwhile our product possessed highly cost effective. Other special
individual demand just need to adapt and there is no difference substantially.
12.Q:Why your machine’s out-factory parameter does not set before, and they have to be
adjusted after the machine sold to us?
Answer:Actually, Our standard parameters are the results of surveying large amounts of
users. It customized to 80% users who can well-adapted this set of parameter. There may be a
little difference between different regions, different users and the inefficiencies and habits.
All these parameter is easy to adjust. With those adjustments, the sewing machines can well-
adapted all kinds of individual practice habits.
13.Q:Compared with a large presser foot lifting electromagnet used in sewing machine
before, how does the small one stand the force?
Answer: do not worry about this. Such design is out of scientific rule. We are just
optimizing the structure. It takes about 12.6Kg when the large presser foot lifter works, but
after optimizing the structure, it takes only 9.2Kg or much less in the same condition. You can
use it with ease.
14.Q:how can workers get used to handle the auto presser foot lifter for they used knee
to control it before?
Answer: It is just a matter of workers’ habits. Workers may not well adjust the change
at the beginning, but if they take an hour to adjust the change, which they will be accustomed
to this structure. On the other hand, this change has another advantage of this machine. It not
only equips excellent sewing functions as well as general sewing machines, but also releases
worker’s knees. Female can wear dress all the summer with this special design. They will not
get illness related knees out of over-working. Workers can be attracted by this advantage.
How to raise presser foot a little instead of too much in order to make sew thin
15 Q: Will the electromagnet be short circuit or electricity leakage with inner-equipped
presser foot lifter, where is so oily?
Answer: we adopt custom- made electromagnet, which is completely enclosed. It will not
lead to oil leakage failure for the wire circuit is made by a pouring meddle. Customers can use
it freely.
16.Q:How to set the function of multi-segment sewing ?
Answer: first step, press full line in the panel,(the last but one button in the second line).
Second step, when the panel flashes yeg-4, we adjust the number to set the sewing-segment
you need, and then press the circle button on the lower right corner. Finally, users want to set
free sewing mode, they only need to press the dotted line.
17.How to set the function of automatic length-fixed sewing ?
Answer: the function of length-fixed sewing function and phase multi-segment sewing are
combined. When users need to set length-fixed sewing, they can handle it like these steps.
First step, press full line in the panel(the last but one button in the second line). Second step,
when the panel flashes yeg-4, change 4 to 1. Third step, press the circle button on the lower
right corner. We can set needle number. Fourth step, after setting needle number, press P to
make sure. If users want to set free sewing mode, they only need to press the dotted line.
18.Q:How to close the small electronic tension device?
Answer: there is an electronic tension device sign on the panel, users can press the button to
open or close the electronic tension device.
19.Q:How to restore to factory settings?
Answer: When the machine is on, please press the button “P”, and then press the button
“presser foot lifter”,and Pd-0000 will be showed on the panel. After that, press the button “P”
again into “62-2101”,and press the button “P”constantly for 4 seconds until one movable
dotted line is displayed on the middle of the panel, which shows that factory settings is
restored. Don’t modify the parameter values behind “62” optionally, otherwise it will fail to
restore to factory settings or restore to error program.
20.Q:How to increase the max speed of the machine?
Answer: When the power is on, please press the button “P”,and then press the button “presser
foot lifter”. Pd-0000 will be displayed on the panel. After that, press the button “P” into the
parameter “P01”,and turn up the value corresponded with the parameter “P01”. If your
machine’s service time is less than three months, don’t turn up the max speed more than
3500r/min; if more than three months, please don’t turn up the max speed more than
4200r/min.For the over-fast speed will short the machine wearing life, and increase the rate
of wire breakage.
21.Q:How to adjust the position of power-off of the machine without the positioning
magnetic steel as installed on the hand wheel
？
Answer: The machine employs built-in positioner, and the position of power-off is electric
controlled. Press the button “P” constantly and the button “circle” at the same time, and then
