5. CRIMPING PROCEDURE
This tool is provided with a crimp adjustment
NOTE
feature. Initially, the crimp height should be verified
as specified in Figure 3. Refer to Section 6, Crimp
i
Height Inspection, and Section 7, RATCHET
(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 locator 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
movable locator drops into the slot in the contact.
Refer to Figure 2. Butt the front end of the wire
barrel against the movable locator.

6. 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.
Proceed as follows:
7. RATCHET (Crimp Height) ADJUSTMENT
Although the ratchet is preset prior to shipment, it is
important to verify the crimp height using a micrometer
or caliper. General use and subsequent wear may
cause the tool to go out of adjustment. It is
recommended that crimp height be inspected, and the
ratchet be adjusted, if necessary, on a regular basis.
Refer to Figure 4, and proceed as follows:
Adjustment
"A"
Screw
CRIMP HEIGHT
DIMENSION "A"
1.32 ±0.05
[.052 ±.002]
1.21 ±0.05
[.028 ±.002]
1. Refer to Figure 3 and select a wire (maximum
size) for each crimp section listed.
2. Refer to Section 5, CRIMPING PROCEDURE,
and crimp the contact(s) accordingly.
3. Using a crimp height comparator, measure the
wire barrel crimp height as shown in Figure 4. If the
crimp height conforms to that shown in the table,
the tool is considered dimensionally correct. If not,
the tool must be adjusted. Refer to Section 7,
RATCHET (Crimp Height) ADJUSTMENT.
Figure 4
1. If the crimp height is larger than recommended,
remove the ratchet wheel adjustment screw and
rotate the adjustment wheel counterclockwise (+) to
a higher setting. Reinstall the screw. Repeat as
required.
2. If the crimp height is smaller than recommended,
remove the ratchet wheel adjustment screw and
rotate the adjustment wheel clockwise (-) to a lower
setting. Reinstall the screw. Repeat as required.
