2. DESCRIPTION
The tool frame features two jaws, a handle, ratchet
adjustment wheel, and an emergency ratchet
release.
The die set consists of an indenter (upper die) and an
anvil (lower die). The tool frame holds a die assembly
with two crimping chambers. See Figure 1. Die
retaining screws are used to secure the dies in the
tool frame.
The tool features a ratchet and an adjustment wheel
with a range of settings. The ratchet ensures that the
tool has completed the cycle and will not release until
the handles have been FULLY closed, unless the
emergency ratchet release is rotated to manually
release the ratchet. The adjustment wheel controls
the amount of handle pressure exerted on the dies
during the crimping procedure.
The dies bottom before the ratchet releases. This
feature ensures maximum tensile performance of
the crimp. DO NOT re--adjust the ratchet.
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 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 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 locator assembly
in place.
8. To disassemble, close the tool handles until the
ratchet releases, remove the nut, locator assembly,
the four die retaining screws, and slide the anvil
and crimper out of the tool jaws.
The ratchet has detents with audible “clicks” as
the handles are closed. The ratchet releases on
the sixth “click”.
4. CRIMPING PROCEDURE
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.

Locator
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.
