6. Tighten the nut and close the handles until the
ratchet releases.
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
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 Section7, 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 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.
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.
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.
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, RATCHET (Crimp Height)
ADJUSTMENT.
