4) Adjusting the synchronizer
1. Loosen screw 󰿿 and remove cover 󱀀.
2. Turn disk 󱀁 on this side by hand, and adjust the adjusting
mark "B" of disk 󱀂 in the rear to edge 󱤨 of disk 󱀁.
3. Temporarily tighten the synchronizer to the lower main
shaft handwheel with screw 󱀃.
4. When the power is turned ON, the sewing machine turns
approximately by one half and stops.
5. Turn OFF the power, and loosen screw 󱀃.
6. Holding 󱤩 section of the synchronizer so as not to move,
turn the upper main shaft handwheel, adjust mark 󱀄of the
handwheel to the position where mark 󱀅 on the machine
head side aligns with it, and temporarily tighten screw 󱀃.
7. Again, turn ON the power, and conrm that the sewing ma-
chine stops at the position where mark 󱀄 of the handwheel
aligns with mark 󱀅 on the machine head side. Then tighten
screw 󱀃.
8. After the adjustment, be sure to attach cover 󱀀 and tighten
screw 󰿿.
9. After the adjustment above has been performed, when the
sewing machine stops at the DOWN position, top end 󱤪of
the looper is located at the position where it has scooped
loop 󱤫 of left needle thread as shown in the gure 1.
When using the synchronizer as UP/DOWN
stop position type without using the thread
trimmer device, change the setting of
the function setting No. 74 to "1 (thread
trimming) / 0 (UP/DOWN position)". Thread
trimmer safety device error occurs unless
the setting is changed, and it is impossible
to operate the sewing machine. So, be
careful.

󰴺 OPERATION
WARNING :
Do not place hands, ngers, etc. within the operating range of the tape cutter when the power is turned ON so as
to prevent accidents caused by abrupt start of the sewing machine.
In addition, do not use the tape cutter unit with safety cover and the like removed.
Press knee switch 󰿿 when cutting the tape at the start or
the end of sewing. The moving knife of the cutter comes
down and the tape is instantly cut. (Cut width is possible
up to 40 mm.)
Besides, when performing sewing without using tape
cutter 󱀁, turn OFF (press to the lower side) cutter motion
switch 󱀀 located on the right side of tape cutter unit ,
and tape cutter 󱀁 does not operate even when the knee
switch is pressed. This action can prevent tape cutter 󱀁
from being carelessly operated by the wrong operation.
For safety sake, turn OFF cutter motion
switch 󱀀when tape cutter 󱀁is not used.

󰴽 ADJUSTMENT OF COMPONENTS
Standard adjustment of assembling adjustment of the tape cutter mechanism components has been performed at the
time of delivery. However, when performing assembling due to the replacement of components or the like, perform the
adjustment with the dimension value below.
Perform the adjustment work by the maintenance engineers who are familiar with the sewing machine
and trained for the safety so as to prevent accidents caused by unfamiliarity or wrong adjustment.
1. Replacing the moving knife or the counter knife
󱀀
󰿿
󱀀
WARNING :
Do not place hands, ngers, etc. within the operating range of the tape cutter when the power is turned ON so as
to prevent accidents caused by abrupt start of the sewing machine.
In addition, do not use the tape cutter unit with safety cover and the like removed.
When the moving knife or the counter knife is worn out and replacement is necessary, perform the replacement by the procedure
below.
1) Remove the whole of tape cutter unit from the sew-
ing machine.
2) Loosen four setscrews 󱀀 and remove the whole of
safety cover 󰿿.

4) Loosen two setscrews 󱀄 and replace moving knife
󱀃.

5) Install safety cover 󰿿 in its home position.
In addition, adjust the dimension of the height of the
cover as shown in the illustration on the left side.

2. Adjusting the angle of the counter knife
󰿿
A
To improve the sharpness of the cutter, it is necessary for
the moving knife to engage with the counter knife slightly
slantwise.
It is the standard that there is a clearance of less than
0.1 mm at the root of plane of engagement 󰿿
1) Slightly loosen two setscrews 󱀀 in the counter knife
(temporarily tightened state) and turn adjustment
screw 󱀁 for adjustment.
2) When turning adjustment screw 󱀁 counterclockwise,
the angle of counter knife in terms of the moving
knife is increased and the knives are set to the state
that they engage with each other more slantwise.

WARNING :
Do not place hands, ngers, etc. within the operating range of the tape cutter when the power is turned ON so as
to prevent accidents caused by abrupt start of the sewing machine.
In addition, do not use the tape cutter unit with safety cover and the like removed.
When the angle to engage with each other
slantwise is large, the initial sharpness is
improved. However, on the contrary, the
blade section is quickly worn out, and the
knives are put in the state of poor lasting
quality.
Accordingly, make the angle of engage-
ment as small as possible within the range
where the tape can be cut.
A : Less than 0.1 mm
3. Adjusting the lift height of the moving knife
The lift height of the moving knife has been factory-adjusted at the time of delivery. However, when performing the re-
placement of the rotary solenoid or the like, perform re-adjustment by the procedure below.
WARNING :
Do not place hands, ngers, etc. within the operating range of the tape cutter when the power is turned ON so as
to prevent accidents caused by abrupt start of the sewing machine.
In addition, do not use the tape cutter unit with safety cover and the like removed.

1) Remove the safety cover.
(For the replacing procedure of the safety cover,
refer to "󰴻. ADJUSTMENT OF COMPONENTS"
p.11.)
2) Loosen solenoid lever clamp screw 󰿿.
3) Loosen lock nut 󱀁of stopper bolt 󱀀.
4) Turn stopper bolt 󱀀, and adjust the height of the
moving knife to 26 mm from the counter knife.
5) Fix lock nut 󱀁of the stopper bolt.
6) Adjust the longitudinal position so that the clearance
between solenoid lever 󱀂 and TC lever 󱀃is 4.1
mm and x the position with clamp screw 󰿿.
Interference of components occurs and the
cutter fails to properly work when it works
unless the clearance between solenoid le-
ver 󱀂and TC lever 󱀃is correctly adjusted.
7) Install the safety cover in its home position.

󰴼TEST CUT
Perform the test cut of the tape cutter by the procedure below using the material for testing before entering sewing of the
products.
󰿿
󱀀
󱀁
󱀂
WARNING :
Do not place hands, ngers, etc. within the operating range of the tape cutter when the power is turned ON so as
to prevent accidents caused by abrupt start of the sewing machine.
In addition, do not use the tape cutter unit with safety cover and the like removed.
1) Sew tape 󰿿 on the material for testing.
2) Press the knee switch to actuate tape cutter 󱀀 and
check that the tape is smoothly cut.
3) When the condition of cutting is not good, it is nec-
essary to adjust the pressing pressure of the cutter.
Loosen lock nut 󱀂 of adjustment screw 󱀁 and
perform the adjustment of the pressing pressure.
* Pressing pressure of the cutter is increased
when adjustment screw 󱀁is screwed up.
Initial sharpness is improved when the
pressing pressure of the cutter is high.
However, on the contrary, the blade section
is quickly worn out, and the cutter is put in
the state of poor lasting quality. According-
ly, make the pressing pressure as low as
possible within the range where the tape
can be cut.
* Standard adjustment value is the pressing pres-
sure of 30 N when measuring with the spring
balancer.
In addition, when the condition of cutting is not good even
when adjusting the pressing pressure of the cutter, perform
the adjustment of the angle of counter knife.
(Refer to "󰴻. ADJUSTMENT OF COMPONENTS" p.11.)
