Mechanical adjustments
The first tension device adjustment
Control the length on the needle after automatic trimming
and the thread length around 4-4.5 cm is the best. Adjusting
the knob in clockwise way, thread will be short; otherwise, it
will be long.
The main tension device adjustment
Control the tension of thread during sewing. Adjusting the
knob in clockwise way, the tension will be bigger; otherwise,
it will be smaller.If the under-thread loose, the tension
should be adjusted stronger, but too stronger would cause
upper-thread be cut easily
Needle gauge adjustment
The left hand holds the backstitch wrench, with the middle
finger back from the lock to the needle, with the thumb and
index finger rotating needle gauge plate. The gage will be
smaller when turning in clockwise way and will be bigger
when turning in anti-clockwise way.
Reverse-sewing button Operation
During sewing, keep pressing the reverse-sewing button , the
machine will be in reverse-sewing state; otherwise, the
machine will be in sewing state.
Press and together to enter technician mode, the pedal control mode can be changed
by adjusting the following parameter:
P30: Pedal Curve mode setup (0:Auto Calculated liner Curve; 1:Two segment liner Curve;
2:Arithmetic Curve; 3:S curve)
P34: Pedal trimming position set (the value is not higher than the parameter [35]);
when adjust P34, need to adjust the value of P35 closer to the value of P36, that’s the sensitivity of
trimming
P35: Press foot lifting (the value is between[34]and[36].)
P36: Pedal back mid position (the value is between[35]and[37] .)
P37: Pedal step upon running position (the value is between[36]and[38]) , if want the machine
to response faster, need to turn down the value of P37, but the value should be higher than P36
P38: Pedal low speed running position(the value is between[37]and[39])
P39: Pedal simulation the largest of value (the value is not lower than the parameter [ 38])
Turn on the power, machine will be up needle position ,the pedal will be as
original state
Step forward to run:
When powered on, the speed will change as the pedal stepped deeper, the
deeper the pedal stepped ,the higher the speed will be.
Step backward to trim and stop:
After sewing, step the rear of pedal, machine will trim and stop. If there is
presser foot lifter accessories, presser foot will lift when stepping backward
further .

mode”, the sewing length can be controlled by the
operator, that is why we called this function as“free
sewing model”. It’s often used for lap seam and bar-
tacking sewing.
Press this key, the machine enters into “fixed-stitch
sewing mode”, the sewing length and segment is
confirmed by the operator through control panel, and
sewing will be finished automatically. The operator
only needs to pedal the speed controller, then will
work automatically till finishing the trimming. It’s
often used for sewing the fixed-length thread
segment and the trademark.
Press this key, the machine enters into “W pattern
bar-tacking sewing mode”, the bar-tacking stitches
and times are set up by the operator through control
panel, and sewing will be finished automatically. The
operator only needs to pedal the speed controller,
then machine will work automatically till finishing
the trimming. It’s often used for straight bar-tacking
sewing.

The common problems and solutions of JK-SHIRLEY IIE
(Powermax)
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.
2.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.
3.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.
5.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.
6.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.
9 .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
7
8
24 25
Attachment 3

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 .
10 .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.
