4. CONTACT SUPPORT ADJUSTMENT
NOTE
i
The contact support is preset prior to shipment, but
minor adjustment may be necessary. Refer to
Figure 3.
1. Make a sample crimp and determine if the
contact is straight, bending upward, or bending
downward.
2. If adjustment is required, loosen the screw that
holds the contact support onto the locator
assembly.
NOTE
i
The ratchet has detents that create audible clicks
as the tool handles are closed.

3. Place a contact with wire into the proper nest
and close the tool handles until the ratchet
reaches the sixth click, or until the contact
support touches the contact.
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.
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 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 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.
