The contact support is preset prior to shipment,

but minor adjustment may be necessary.

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.

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

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.

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.
