3. Slightly loosen the nut that holds the locator assembly onto the tool frame.
4. Move the contact support as required to eliminate the bending of the contact.
5. Tighten the nut, then close the tool handles until the ratchet releases.
6. Remove and inspect the contact.
7. Crimp another sample. 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
Before using the tool, the contact crimp height should be verified as described in Section 5.
1. Refer to Figure 1, and select a contact for the wire size being used. Strip the wire to the length
indicated in Figure 1, taking care not to nick or cut wire strands. Identify the appropriate crimping
chamber according to the wire size markings on the tool.
2. Close the tool handles until the ratchet releases, then allow the handles to open fully.
3. Holding the contact by the mating end and so that the open “U” of the wire barrel faces the top of the
tool, insert the contact—insulation barrel first—into the appropriate crimping chamber from the front of
the tool. Position the contact up into the nest so that the locator drops into the slot in the contact. See
Figure 3. Move the front end of the wire barrel against the locator.
CAUTION
Make sure that both sides of the insulation barrel are started evenly into the crimping chamber. Do not attempt to crimp an
improperly positioned contact.
4. Hold the contact in position and squeeze the tool handles together until the ratchet engages
sufficiently to hold the contact in position. Do not deform the wire barrel or insulation barrel.
5. Insert the stripped wire into the wire barrel until it butts against the wire stop as shown in Figure 3.
6. Holding the wire in place, squeeze the tool handles together until the ratchet releases, then allow the
handles to open. Remove the crimped contact.
NOTE
The crimped contact may stick in the crimping area, but the contact can be easily removed by pushing down on the top of the
locator.
7. Check the contact crimp height as described in Section 6. If necessary, adjust the crimp height as
described in Section 7.
