Procedures
1.Make sure that the tool number and the wire size are met.
2.Open the grips fully.
3.Insert the contact fully into the nest.
4.Strip the wire and insert it to the contact until the end of
it hits against the nest.
5.Close the grips fully until the ratchet is released.
6.Open the grips to pick up the contact crimped with wire.
7.Make sure that the shape of the crimped work is appropriate.

Failure Item Failure Description Cause
1)Malformation of
Pull strength is out of specification. The wire size is out of
the crimped area
(Wire barrel)
the specification, or
abrasion of the tool
Incomplete
crimping of
the barrel
2)Deformation of
the terminal
1.Bend
2.Twist
3.Deformation
of the barrel
3)Variation in crimp
height
The crimping height of the tool
is not fixed.
Occurred when grips
were incompletely
tightened (tightened
half way) but in the
position where they can
be open due to the
abrasion or deformation
of the ratchet.
Due to the displacement
in position or uneven
planes of the wire
crimping part and
cladding insulation
crimping part of the tool.
To make sure easily,
insert the contact into
the insulator housing to
check that no floating
of the contact exists.
The crimper is cracked.
