Checking procedure
• Check whether there is a
clamp feeling when clamp
lever is fully pressed until
it will go no further.
• Check whether ratchet is
released in the state that
pressure block comes
closely in contact with
base plate face.
• Check that pressure
block comes closely in
contact with base plate
face and each punch is
smoothly opened without
friction after clamp lever
has been released.
• Check through eye-ob-
servation whether each
punch has neither defor-
mation nor breakage.
Perform an appearance
inspection with the first
connection product.
• Check whether con-
nector clamp comes in
contact with set position
when clamp lever is fully
pressed until it will go no
further.
• Check through eye-ob-
servation whether there
is no lack or breakage of
the respective compo-
nents.
In case of trouble
• Shut-height is im-
proper and connection
is not correctly per-
formed.
• Shut-height is im-
proper and connection
is not correctly per-
formed.
• Shut-height is im-
proper and connection
is not correctly per-
formed when pressure
block does not come
closely in contact with
base plate face.
• Connection is not cor-
rectly performed when
press fitting punch
or lock punch is de-
formed or broken.
• Connection is not cor-
rectly performed when
connector lamp does
not come in contact
with set position.
• Connection is not cor-
rectly performed.
Cause
• Shank installing
position is improp-
er.
• Ratchet installing
position is improp-
er.
• Deformation of
each punch.
• Mixture of foreign
materials in slid-
ing parts.
• Trouble of shut-
height or the like.
• Mixture of for-
eign materials in
sliding parts.
• Mixture of for-
eign materials in
clamp or the like.
• Mixture of foreign
materials in slid-
ing parts.
• Trouble of shut-
height or the like.
If the jig is defective, do not perform disassembling or the like. Please contact us for repair.
Corrective measure
• Please request us
for repair.

III. Operating procedure
1. Mounting the ground plate
1) Face upward signal face ②of FPC ①and polarization
mark ④of the ground plate ③.
2) Mount the ground plate ③so that you do not touch
signal section ②of FPC by hand.

2. Inserting FPC
1) Adjust connector main body ②and polarization mark ④
of the ground plate ③to the same direction.
2) Insert FPC ①until it comes in contact with the inside of
connector main body ②.

FPC ①
Cautions when inserting FPC
1. The connector main body and the ground
plate will be broken at the time of connec-
tion unless the connector main body and
the polarization mark of the ground plate
are set in the same direction.
2. Insertion may be difcult when FPC is warped.

3. Preliminary insertion of the ground plate
1) Making FPC ①come in contact with the inside of
connector main body ②, insert ground plate ③into the
connector main body.
2) Insert the ground plate so that preliminary insertion
position ④comes in front of preliminary insertion
reference ⑤of the connector main body.

Checktobesurethatthecomponentthathasbeeninsertedsatisesthefollowingqualitystandards.
A (OK) : Angle when the ground plate is inserted into the connector main body should be less than 10 degrees.
B (NG) : Ground plate is slantingly inserted. Deformation of the ground plate will be caused.
C (NG) : Lower click of the ground plate is widened. rise of the ground plate occurs when setting the connector.

FPC ①
Cautions when inserting the ground plate
1. Do not use a ground plate which has been excessively warped at the time of preliminary insertion.
2. When the directions of FPC and polarization mark are reverse each other, perform the work from
the rst step without performing the preliminary insertion.
3. After completion of preliminary insertion, do not pull the FPC since the ground plate may come off.

deformation of the ground plate or the like.
Do not perform the work by force. Return again to the state of the preliminary insertion of the ground plate
(Slide to the right-

4. Setting procedure of the connector
1) Face upward polarization mark side ①and slide
connector clamp ②to the right-hand side to open it.
2) Adjust connector main body ④to connector guide face
⑥of connector holder ⑤.
3) Making the connector main body come in contact with
end face of the connector holder, slide connector clamp
⑦to the left-hand side to close it.
When the connector clamp is caught on the
ground plate and not closed by the spring
force alone, lightly press the connector
clamp by ngers up to the set position.

Releasing procedure of the clamp lever
When the ratchet is not released even when the clamp
lever has been fully pressed or you want to temporarily
stop the clamp lever, do not return the clamp lever by
force. Pressing ratchet release lever ①located in the
rear of the tool, release the clamp lever.
(See the enlarged drawing of ratchet section.)
5. Connection work
1) Making connector main body ①come in contact with
the end face of the holder, press FPC ②.
2) Fully press down clamp lever ③until you obtain a
feeling of clamping.
3) Return upward clamp lever ③and release it.
4) Connection work has been completed.
