4. Slightly loosen the nut that holds the locator
assembly onto the tool frame.
5. Move the contact support as required to
eliminate the bending of the contact.
6. Tighten the nut and close the handles until the
ratchet releases.
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
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 3. Butt the front
end of the wire barrel against the movable locator.
7. Remove and inspect the contact.
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
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.
4. Hold the contact in position and squeeze the
tool handles together until ratchet engages
sufficiently to hold the contact in position. Do NOT
deform insulation barrel or wire barrel.
NOTE
i
This tool is provided with a crimp adjustment
feature. Initially, the crimp height should be
verified as specified in Figure 4. Refer to
Section 6, CRIMP HEIGHT INSPECTION, and
Section 7, 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 3 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.
5. Insert stripped wire into contact insulation and
wire barrels until it is butted against the wire stop,
as shown in Figure 3.
6. Holding the wire in place, squeeze tool handles
together until ratchet releases. Allow tool handles
to open and remove crimped contact.
NOTE
i
The crimped contact may stick in the crimping
area, but the contact can be easily removed by
pushing downward on the top of the locator (see
Figure 3).
7. Check the contact’s crimp height as described in
Section 6, CRIMP HEIGHT INSPECTION. If
necessary, adjust the crimp height as described in
Section 7, CRIMP HEIGHT ADJUSTMENT.
CAUTION
!
Damaged product should not be used. If a
damaged contact is evident, it should be cut from
the wire and replaced with a new one. Do not
reterminate contacts.
