Warning

Injury-Caution

Do not touch nor insert fingers to the punch, the cutter part
especially during operation. You may have serious injury
such as cutting hands, fingers.
Put and place the tool on to stable working table considering
its weight otherwise you may have serious injury by the tool
dropping, fallen instruments.

Injury-Use the tool for intended purpose only otherwise you may
have injury.

Fatigue-Avoid long time continuous operation nor operation in badhealth otherwise you may get ill. Take rest for 10 to 15 min.
every one hour.

1. General
Hand crimping tool is a manual tool to connect wire cable to connector contact. Handlingand operation of the tool is easy and it makes sure to have uniform quality connection. Inorder to keep such characteristics, it is necessary to do crimping work under proper conditions.
Lack of work control may cause unexpected defect.
For crimping work, prepare stripped wire besides contact and set this wire portion into
predefined position of the tool. For each wire size and contacts, dedicated hand crimping
tools are available.

Safety caution for healthLong time, continuous operation nor operation in fatigued state is not favorable to health.
Get a proper amount of rest, and relax, then start operation.

The hand crimping tools, when delivered, have been already adjusted for use with thespecified contacts and asterisked (*) wires listed in Table-1 (page 9). If further adjustment
is required, refer to this procedure, item 4 (page 7). Before operation and/or adjustment,
confirm the tool moves smoothly by operating the arm for 2 or 3 times without insertingthe contact1) Contact loading (Fig.-2)
Fully open the arm, hold center portionof the tool by left hand and insert thecontact into the hole behind the male die2) Wire insertion (Fig.-3)
Insert a stripped wire into the contact
until the insulation butts against the wire
insulation stopper and maintain the wire.
Take care of the wire insertion depth.
In case the depth is deep or shallow, it
might be a cause of conduction error,
lower cable retention and so on.

While holding the wire in place, close thearm by left hand.

Strip length

Even closed amount is not enough, it is
not cared since purpose of this process is
to retain the wire in the contact.

While the wire is retained in place, squeeze
the arm completely by both hands.
Loosing the hands allows the arm to open
automatically and the wire crimping iscompleted. In case the arm does not open,
close the arm again since crimping work wasinsufficient.
5) Contact taking off
Remove the crimped contact by pulling on
the wire carefully. Pulling in a high-handed
manner might cause deformation of thecontact.
6) Appearance, crimp height check (Fig.-5)(1) Check appearance of the crimped contact
to see the wire is crimped correctly.
(2) It is best that bell mouth is made at theboth ends uniformly. Even no bell mouth
at both ends, it is good crimped contact.
Take care of much bell mouth contrary,that might be a cause of breaking wire,
lower cable retention.
(3) Check crimp height. Do it even atmoments during operation

User should only adjust the hand crimping tool by himself when:① The arm does not move smoothly② The crimp height is not correct and required to be adjusted
1) Lubrication
The arm and the dies are engaged though toggle and link mechanism.
Before starting the crimping work, close and open the arm several times with no contact
loaded. If it does not move smoothly, lubricate the sliding parts carefully.
(1) OilOrdinary machine oils are available for lubrication. However, avoid the use of highviscosity lubricants such as grease.
(2) Amount of oil
Take care not to apply too much oil. Only several drops are needed.
Much oil would contaminate the hands and also saturate to the crimping dies,that might affect crimping performance, crimp height and crimped contact
characteristics.
2) Crimp height adjustment
Make adjustment carefully since it would affect crimping performance directly(1) Lock loosing (Fig.-6)
Close the arm until the locking screw becomes visible through the opening.
Then loosen the screw with a hexagonal wrench. It should be loosened by no more than
1/2 to 1 turn.

Turn to adjust the die position adjusting screw.
Turning right raises the die, turning left
lowers it.
Then crimp the contact and check the crimp
height conforms to that shown in Table 1(page 9).
(3) Fixing block (Fig.-8)
Attachment of the fixing block to the tool
makes it possible to avoid crimp heightfluctuation by the lock screw loose
Match convex part of the block and concave
part of the die adjustment screw, then put it
there and fix with the front cover.
