I. MACHINE (ABOUT THE SEWING MACHINE)
Precautions for use
Following items have to be checked every working day before the operation of the machine and before the start
of work hours.
1. Ascertain that the oil pan is lled with the predetermined amount of oil.
2. Never operate the machine unless the oil pan has been lled up with oil.
3. Ascertain that the pressure gauge indicates the designated air pressure of 0.5 MPa.
* (This is necessary particularly when the compressor is stopped for a lunch break or the
like.)
If the compressed air pressure is equal to or less than the designated value, troubles such
as interference between the parts can occur. It is therefore necessary to carefully check
the compressed air pressure.
4. Check whether the needle thread/bobbin thread need to be replenished.
5. To perform sewing immediately after turning ON the power switch, perform trial stitching
rst, then proceed with sewing of actual products after the test sewing.
6. In the case drainage water accumulates in the regulator section, expel it from there before
starting work.
7. Be sure to turn ON the power to the sewing machine after returning the loop clamp (loop
feeder unit) inside the unit cover.
* Be aware that the loop clamp interferes with the unit when the ready key is pressed while
the loop clamp rests on the sewing machine side after the power to the machine is turned
ON

Heat the heat cutter to enable its operation, it is necessary to turn ON the heat cutter controller power switch K.
The power switch of the heat cutter is independent from the sewing machine power switch. It
is therefore necessary to turn OFF not only the heat cutter controller power switch but also
sewing machine power switch J when the sewing machine is not used.
In addition, it should be remembered that the heat cutter requires a certain period of time until
it becomes sufciently hot for use after turning ON the power switch. To ensure that the heat
cutter is operable whenever necessary, be sure to turn ON heat cutter controller power switch
K in prior and check that the heat cutter temperature is sufciently high. (For the adjustment
of temperature, refer to "I.5-8. Adjusting the heat cutter temperature" p.20.)

(2) Precautions with the emergency stop switch
When emergency stop switch ❶ stays ON, the sewing machine cannot be powered up even if you turn
ON/OFF the power switch. The work clamp foot of the sewing machine may depress the loop clamp or
the loop loosening rod according to the operation timing of emergency stop switch ❶. If this phenome-
non occurs, turn OFF the power to the sewing machine and manually lift the work clamp foot of the sew-
ing machine to move it so as to avoid interference. Then, re-turn ON the power to the sewing machine.

5-2. Winding a bobbin
(1) To wind a bobbin while the sewing machine is performing sewing
Thread the bobbin winder and wind the bobbin
thread onto the bobbin as illustrated in the gure.
(2) To wind a bobbin independently
A
In the case you only want to carry out bobbin winding
on the sewing machine, unthread the needle and remove
the bobbin from the hook.
① Displaying the bobbin thread winding screen
Press bobbin winding button A on the shoelace loop data
input screen (blue), and the bobbin winding screen appears on
the screen.
② Starting bobbin winding
B
Press the start switch, and the sewing machine rotates to start
bobbin winding.
③ Stopping the sewing machine
Press stop button B, and the sewing machine stops and
returns to the normal mode. If you press the start switch again
during bobbin winding, the sewing machine stops under the bob-
bin winding mode. If you press the start switch again in this state,
the sewing machine re-starts bobbin winding. Use this operating
procedure when you want to wind thread on two or more bobbins.
The bobbin winding will not start immediately after
turning the power ON. To activate the bobbin winding
function, set a pattern number or the like rst, then press
the set ready key to invoke the sewing screen. In
this state, the bobbin winding function is enabled.

5-3. Thread clamp device
Trouble of sewing (slip-off of needle thread, stitch skipping, or stain of needle thread) at the time of high-
speed start can be prevented with the thread clamp device.
The thread clamp device will operate when the thread clamp button has been selected , but it will
not operate when the thread clamp button has not been selected .
Changeover of ON/OFF motion is performed with key. When the thread clamp device is in the
OFF state, the sewing machine is automatically set to the soft-start mode.
1. When memory switch is "1" (prohibited), the thread clamp does not work. Fur-
thermore, the thread clamp key will not be displayed.
2. Memory switch, refer to "II.2-26. How to change the memory switch data" p.75.
* Matters that demand special attention when using the needle thread clamp
(1) In case of with the needle thread clamp (motion), make shorter the length of needle thread remaining on
the needle at the sewing start for use. When the length of needle thread is lengthened, needle thread
on the wrong side of material is apt to protrude. In addition, when the length is excessively lengthened,
the end of needle thread held by the needle thread clamp may be rolled in the seams.
1)
1) In case of with the needle thread clamp, the
standard of the length of needle thread is 33 to
36 mm.
33 to 36 mm
2) When needle thread is long after replacing thread
or the like or sewing while holding needle thread
3)
by hand, turn OFF the THREAD CLAMP
key.
3) When the needle thread held with the thread
clamp is rolled in the seams, do not draw the
material forcibly and 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) It is possible to adjust needle thread shorter by making the needle thread clamp work while holding the
stabilized sewing at the start of sewing and the gathering (bird's nest) of needle thread on the wrong
side of material can be lessened. However, for the pattern which the stitch length for neatly rolling in
needle thread is short, needle thread may protrude from the wrong side of material.
In addition, thread waste could accumulate around the hook due to thread trimming when the thread
clamp device is used. Be sure to periodically clean inside the hook cover referring to "II.1-12. Cleaning
inside the hook cover" p.113.

5-4. Placing a shoelace loop
❸
❹
❷
❶
Pass the loop through guide ❶, pull up lever ❷ at
the roller section and insert the loop under roller ❸.
When you route the shoelace loop
under the gear, insert it until it appears
from the loop cutting knife.
* When the heat cutter controller power is ON, a
shoelace loop is fed by means of the motor by
pressing loop feeding switch ❹ of the heat cutter
controller is pressed.
When the machine is used under a high
shoelace loop tension, the entire length
of the fed shoelace loop is shortened.
In such a case, malfunctions such that
the shoelace of the predetermined
length cannot be sewn or that the shoe-
lace loop cut edge is not
straight can occur. To prevent those malfunctions,
it is necessary to adjust
the shoelace loop tension
adequately.
5-5. Adjusting the shoelace loop tension
When you have changed the shoelace loop, you need to re-adjust
A
the shoelace loop tension without exceptions.
Press the shoelace loop tension button A on the sewing
screen.
The more the shoelace loop tension is adjusted in a negative direction, the less the shoelace loop tension becomes. (The shoelace loop tension can be set and stored in memory on a sewing-pattern by sewing-pattern basis.)
As a guide, adjust the shoelace loop tension so that the entire
length of the shoelace loop fed from the shoelace loop feeding
section and clamped at the loop clamping section is shorter than
the entire shoelace loop length displayed when selecting a sewing pattern by approximately 1 mm.
To change the shoelace loop length after the aforementioned
adjustment, nely adjust the feed length so that the entire loop
length as shown in the relevant sewing pattern is achieved, refer-
ring to in
p.72
.
If the sewing machine is operated under a high shoelace loop tension, the entire length
of the shoelace loop fed becomes shorter than required. In this case, problems such that
the shoelace loop cannot be sewing at the predetermined length or that the cut end of the
shoelace loop is not straight can occur. To prevent such problems, adjust the shoelace loop
tension adequately.

5-6. Method for changing the loop width
❶
❷
A
1) To change the loop width, loosen setscrew ❷ of
left-side shoelace loop guide ❶ and adjust the
guide width so that it matches the shoelace loop
width. Lightly pressing guide ❶ against shoelace
loop, adjust guide ❶ to allow the shoelace loop
smoothly pass through the guide with no lateral
play.
The right-side shoelace loop guide is
used as an across-the-width reference.
So, it is not necessary to adjust it every
time the loop width is changed. How-
ever, adjust the guide position in the
similar matter as described above if the
lateral position of shoelace loop does
not align with the reference.
2) Enter a value of shoelace loop width into shoe-
lace loop width setting section A on the opera-
tion panel screen. At the same time, change the
dimensions of a seam for attaching a shoelace
loop. Refer to "II.2-5. How to change the shoe-
lace loop length" p.32 for the method for
changing the seam dimensions.
If the bartacking width of which is ex-
tremely wider than the shoelace loop
width setting specified through the
operation panel is sewn, the garment
body presser and the loop clamp can
interfere with each other (error No.
M596). If the alarm is given, change the
bartacking width setting to decrease the
bartacking width.

5-7. Start switch
CAUTION
When you press the start switch, the garment body presser comes down. At the same
time, the loop clamp moves toward the sewing machine at a high speed. Take added care
to keep your hands away from the loop clamp during work.
:
Once you have completed preparation for sewing,
❷
you can bring the sewing machine into operation
by pressing start switch ❶.
When the loop clamp ❷ has clamped the shoe-
lace loop, operation of the start switch ❶ will be
accepted.
1. Operate the sewing machine taking
care not to allow your hands move
above safety cover ❸ since the
hands can interfere with the loop

held pressed for a sufciently long
time, sewing will be interrupted. Be
sure to keep the start switch fully
held pressed.
while the loop clamp clamps the
shoelace loop and travels to the
standby position after the comple-
tion of sewing. In that case, the loop
clamp will not stop at the standby
position but will move directly to
the sewing position to start the next
sewing. Be sure to exercise added
care during this procedure.

5-8. Adjusting the heat cutter temperature
Heat cutter
Heat cutter controller
It is necessary to adjust the heat cutter tempera-
ture so that it can cut the shoelace loop to be
sewn. (Standard temperature: 360 °C)
Gradually raise the heat cutter temperature while
carrying out trial stitching the shoelace loop to be
sewing until the heat cutter is hot enough to cut
the shoelace loop and weld the cut end without
fail. If the temperature is raised excessively high,
the loop cut end will melt and cut thread waste will
be likely to be produced. In such a case, lower the
heat cutter temperature.
Preset temperature increases.
