3. INSTALLATION AND REMOVAL OF DIE SET AND
LOCATOR ASSEMBLY (Figure 1)
1. Open the tool handles and remove the two die
retaining screws from the tool jaws.
2. Place the wire anvil so that the chamfered side
and the marked surfaces face outward, when
mounted in the moving jaw of the tool frame.
3. Insert the short die retaining screw through the
jaw and through the anvil die, and tighten the screw
just enough to hold the die in place. Do not tighten
the screw completely at this time.
4. Place the wire crimper so that the chamfered side
and the marked surface face outward, when
mounted in the stationary jaw of the tool frame.
5. Insert the long die retaining screw through the
jaw and through the crimper die, and tighten the
screw just enough to hold the die in place. Do not
tighten the screw completely at this time.
6. Carefully close the tool handles, making sure that
the anvil and crimper align properly. Continue
closing the tool handles until the ratchet in the tool
frame has engaged sufficiently to hold the anvil and
crimper in place, then tighten both die retaining
screws.
7. Place the nut onto the end of the long screw and
tighten the nut enough to hold the terminal support
in place.
8. To disassemble, close the tool handles until the
ratchet releases, remove the nut, terminal support,
the two die retaining screws, and slide the anvil and
crimper out of the tool jaws.
NOTE
i
The ratchet has detents with audible “clicks” as the
handles are closed. The ratchet releases on the
sixth “click.
4. CRIMPING PROCEDURE
NOTE
i
This tool is provided with a crimp adjustment
feature. Initially, the crimp height should be verified
as specified in Figure 3. Refer to
Section 5, Crimp Height Inspection, and Section 6,
crimp height Adjustment, to verify crimp height
before using the tool to crimp desired contacts and
wire sizes.
Refer to the table in Figure 1 and select wire of the
specified size and insulation diameter. Strip the wire to
the length indicated in Figure 1, taking care not to nick
or cut wire strands. Select an applicable contact and
identify the appropriate crimp section according to the
wire size markings on the tool. Refer to Figure 2 and
proceed as follows:
1. Hold the tool so that the back (wire side) is facing
you. Squeeze tool handles together and allow them
to open fully.

2. Holding the contact by the mating end, insert the
contact through the front of the tool and into the
appropriate crimp section.

3. Position the contact so that the mating end of the
contact is on the terminal support side of the tool,
and so that the open “U” of the wire barrel faces the
top of the tool. Place the contact up into the nest so
that the wire barrel is centered on the wire crimper.
CAUTION
!
Make sure that both sides of the wire barrel are
started evenly into the crimping section. Do not
attempt to crimp an improperly positioned contact.
5. CRIMP HEIGHT INSPECTION
Crimp height inspection is performed through the use
of a micrometer with a modified anvil, commonly
referred to as a crimp-height comparator. TE
Connectivity does not manufacture or market crimp-
height comparators. Detailed information on obtaining
and using crimp-height comparators can be found in
Instruction Sheet 408-7424.
