1 Q: How to lift presser foot when we are sewing?
Answer: The control system of this type of sewing machine has the function that operators
just need to press the button “Presser Foot Lift”continuously to achieve circulatory Switch
between four patterns “no lift presser foot- midway parking presser foot lift—trimming
parking presser foot lift—Midway parking and trimming parking presser foot lift ”flexibly.
When users set “presser foot lift ” during sewing and after cutting , icon of this function will
be lighted in the panel, so the machine can achieve this function; besides, when the presser
foot presses the cloth in sewing, half reverse tread trample also can realize the presser foot
function.

Q: How to lift presser foot automatically after cutting?
Answer: The control system of this type of sewing machine has the function that only
operators press button “Presser Foot Lift”continuously, which the sewing machine can
achieve circulatory Switch between four patterns “no lift presser foot- midway parking
presser foot lift—trimming parking presser foot lift—Midway parking and trimming parking
presser foot lift ”flexibly. When users set“trimming parking presser foot lift” , icon of this
function will be lighted in the panel, so this function can be achieved. And presser foot will be
putted down after finishing cutting after the time of presser foot lifting set by the system and
if you want to lift the presser foot again just to half counter trample to realize the presser foot
function.

Q: Why workers feel heavy when trimming?
Answer: Too low rotating speed results in the heavy feeling when cutting, or Pedal counter
trample too much when cutting.
A
、
For low rotating speed , workers could solve this problem to adjust the technician
parameters 05. First, to press button“ P ”meanwhile to press the button“presser foot
lift”when“Pd-0000
appeared, pressing“P” again to enter the technician parameter “05-
XXXX”
，
then adjust “05” to “05-0270”(The actual setting value is 270), then press“P”to
save and exit .Watching out the speed of trimming can’t be set too large in case of resulting in
a lot of noisy, and cutting will be unsteady. Please follow the rules of operation as the
standard strictly. Generally speaking, adjustment values is 230-270.
B
、
For reverse tread resulting in cutting route too big, to adjust rear number of "Technician
parameter" and " the number behind 34"bigger and always set parameter from 50 to 180. if
Value is too small, trimming will be felt heavy; too big , when presser foot life during sewing
will be easy to mistakenly trigger cut line. According to the worker’s habit to make adjust,
operators usually set between 80 and 100 appropriately.
.
4.Q: Presser foot can’t be controlled well when half reverse tread, and trim mistakenly.
This phenomenon is caused by unreasonable parameter settings of trimming position
and Presser Foot Lift position
.（
the method of getting into The technician parameters as
above
）
Increase the value of P35 appropriately. Increase the numerical difference of "35"
and "34" . bigger this difference is , more obvious time of "trimming" and " presser foot lift"
action gap will be , on the contrary, the smaller the value is, the easier to mistakenly trimming
when presser foot lift. This difference is generally not less than 50, the closer "35" number
and parameter value "36" number parameter is, the easier to fulfill "half reverse tread presser
foot lift" is, but the difference of the "36"should be no less than 100, otherwise the presser
foot will automatically lift when stopped in the middle. This parameter can be adjusted
depending on the habits of the operator.

.
Q: Why it can’t trimming after adjusting reverse tread parameters ?
This phenomenon is caused by the small setting of the pedal cut line position which
the parameters (Technician parameters 34) is set too small. This parameter can be adjusted
appropriately larger than before. Generally it often set between 80-100. When setting this
parameter, the value can not be bigger than "technicians parameter" and "35" setting value.

.
Q:The function “presser foot lift during sewing” wasn’t open, why the presser foot lift
when stop sewing?
Answer: This phenomenon is caused by unreasonable parameter settings, and you will
turn down technician parameters (press P + button presser foot lift to enter ) value of P35
appropriately, always increase it between 200 and 300, at the same time, operators would
better to make the value of P36 to about 500 . If the difference between parameter "36" and
"35" is less than 100, the presser foot will lift automatically when half-way stop.
.
Q: why the machine starts sewing before putting down presser foot?
Answer: this phenomenon exist because of the delay of presser foot putting down set
too shortly. Please press and hold down the “P” after power source being opened, meanwhile
then press the "circle" on the panel, entering “system member parameter model”.Please turn
the parameter values of “P44”up appropriately which usually between 200 and 300.Bigger
the values is ,longer the time of starting sewing delay is, which means that the interval bet
between two action “Putting down presser foot” and “Starting sewing” is longer, vice versa.
It can be adjusted appropriately according to operator’s habits and different sewing art.
.Q: how to adjust the problem of presser foot putted down too slowly?
Answer: this phenomenon caused by the delay of presser foot putting down set too shortly.
Please press and hold down the“P”key after power source being opened, meanwhile then
press the "circle" button on the panel, entering “ system member parameter model”.Please
turn the parameter values of “P44”down appropriately which usually between 200 and 300.

Q: how to make presser foot raise half when machine is bone (sewing the material
from thin to thick)?
Answer: this problem involve in operation habits, and in this condition it is
