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.

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.
