*8. Make another sample crimp. If the contact is
straight, tighten the contact support screw. If the
contact is still being bent during crimping, repeat
the adjustment procedure.
5. 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
6, CRIMP HEIGHT INSPECTION, and Section 7,
RATCHET 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 — insulation barrel first — 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 and insulation barrels
must face 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.
CAUTION
!
Make sure that both sides of the insulation barrel
are started evenly into the crimping section. Do
NOT attempt to crimp an improperly positioned
contact.
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. Tyco
Electronics 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.
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 listed in Figure 3. 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 ADJUSTMENT.

CAUTION
!
Damaged product should not be used. If a
damaged contact is evident, it should be
replaced. Contacts must not be re- terminated.
7. RATCHET 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:
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.
Proceed as follows:
1. Refer to Figure 1 and select a wire (maximum
size) for each crimp section listed.
3. If the crimp cannot be made to conform to the
recommended crimp height, the tool or die set
must be replaced. See Section 9,
REPLACEMENT.
