[In case of the mechanical valve pedal]
1) Set a workpiece under the feeding frame and
depress pedal 󱤨of the pedal switch. Then the
feeding frame comes down.
When the foot is detached, the feeding frame
returns to its home position.
The lowering speed of the feeding frame
changes according to the depressing amount.
This is used when positioning the parts.
2) When positioning the workpiece and depress-
ing pedal 󱤩, the feeding frame comes down to
the bottom and holds the workpiece.
3) Depress pedal 󱤪when the feeding frame
comes down to the bottom and sewing starts.
[For the 2-step stroke pedal (PK47)]
* Refer to "II-2-29. Using 2-step stroke function" p.79.

5-2. Needle thread clamp device
By actuating the needle thread clamp device, trouble of sewing at the high-speed start (needle thread
slip-off, stitch skipping or needle thread stain) is prevented, and can reduce gathering (bird's nest) of
needle thread on the wrong side of cloth while keeping stable sewing. When mounting the IP-420,
changeover of motion ON/OFF is performed with key.
When the needle thread clamp device is OFF, the machine automatically operates at slow-start.
When memory switch No. 35 is : prohibited, the thread clamp does not work. In addi-
tion, key is ineffective.
* Matters that demand special attention when using the needle thread clamp device
Refer to the list below for the contents of memory switches where the thread clamp unit can be set.

2 : H type intermediate (#20 to #5)
3 : H type thick thread (#5 to #2)
0 : Front
1 : Rear (standard)
[Regarding thread clamp unit]
Change the set value of memory switch U69 according to the thickness of needle thread. The value has
been set to 1 : Thin thread at the time of delivery.
Commendable value is Set value : 1 for thread count #50 to #8, Set value : 2 for thread count #20 to
#5, and Set value : 3 for thread count #5 to #2. (The value will change in accordance with the kind and
thickness of the actual thread and the kinds of materials to be sewn. Set the value by adjusting to the
state of needle thread on the wrong side of materials.) In addition, it is possible to select the thread
clamp position by means of memory switch U70. If the sewing material is tucked in or set in at the be-
ginning of sewing in case of using thicker thread such as yarn count #5 to #2 or in any other occasion,
select rear position of thread clamp by means of Memory switch U70.
Use the set value of the memory switch which is adjusted to the thread clamp unit type.
When the setting is wrong, the thread clamp fails to properly function. So, be careful.

(2) When the thread clamp is used, and bobbin thread at the sewing start appears on the right side of
material, reduce thread tension at the sewing start (2 to 3 stitches) and bobbin thread becomes less
conspicuous.
[Example of setting]
Tension of 1 to 2 stitches at the sewing start is “20” when sewing tension setting is “35”.
* For setting of tension at the start of sewing, see of "II-2-8(1) Editing the thread tension" p.32.
1. Thread at the start of sewing may be rolled in case of some patterns. When thread is rolled
in even after performing adjustment of (1) or (2), use the sewing machine with thread
clamp OFF.
2. Thread clamp failure may occur in the state that thread waste is jammed in the thread
clamp device. Remove the thread waste referring to
"III-1-7. Needle thread clamp device" p.107.
5-3. How to use the plastic blank (supplied with the machine as an accessory)
1) Machine the plastic blank supplied with the
machine according to the stitching shape.
2) Attach the plastic blank to the feeding frame as
illustrated in the gure.
Use a sponge sheet or rubber sheet
supplied with the machine in combi-
nation with the plastic blank, if neces-
sary.

When needle thread is excessively long at the time of using the thick thread, the end of nee-
dle thread held with the needle thread clamp is rolled in the seams, and slip of position of
material may occur or needle breakage may be caused.
(1) When with thread clamp (motion), use the sewing machine after adjusting the needle thread length
at the start of sewing to 40 to 50 mm. When the needle thread length is too long, the needle thread
end held with the needle thread clamp may be rolled in the seams.
40 to 50 mm
1) In case of with the needle thread clamp, the
standard of the length of needle thread is 40 to
50 mm.
2) When needle thread is long after replacing
thread or the like or sewing while holding
needle thread by hand, turn OFF the THREAD
CLAMP key .
3) When needle thread held with the needle
thread clamp is rolled in the seams, when error
has occurred, or when needle thread is held
entangled with the needle thread clamp, do not
forcibly draw the cloth, but cut the connected
needle thread with scissors or the like. The
seams cannot be broken because of the nee-
dle thread at the start of sewing.
