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 terminal by the mating end, insert

the terminal — insulation barrel first — through the

front of the tool and into the appropriate crimp

section.

3. Position the terminal so that the mating end of

the terminal is on the front side of the tool, and so

that the open “U” of the wire and insulation barrels

face the top of the tool. Place the terminal up into

the nest.

4. Rotate the tool sufficiently to be able to view the

front side of the wire crimper, and position the

terminal so that the front edge of the wire barrel is

even with the front edge of the wire crimper, as

shown in Figure 3.

Make sure that both sides of the insulation barrel

are started evenly into the crimping section. Do

NOT attempt to crimp an improperly positioned

terminal.

5. Hold the terminal in position and squeeze the

tool handles together until ratchet engages

sufficiently to hold the terminal in position. Do NOT

deform insulation barrel or wire barrel.

6. Rotate the tool so that the back (wire side) is

once again facing you.

7. Insert stripped wire into terminal insulation and

wire barrels until the end of the wire is even with

the edge of the wire barrel and wire crimper, as

shown in Figure 3.

8. Holding the wire in place, squeeze tool handles

together until ratchet releases. Allow tool handles

to open and remove crimped terminal.

The crimped terminal may stick in the crimping

area, but the terminal can be easily removed by

pushing downward on the mating end of the

terminal.

9. Check the terminal’s crimp height as described

in Section 5, CRIMP HEIGHT INSPECTION. If

necessary, adjust the crimp height as described in

Section 6, RATCHET (Crimp Height)

ADJUSTMENT.

5. CRIMP HEIGHT INSPECTION

Crimp height inspection is performed through the use

of a micrometer with a modified anvil, commonly

referred to as a crimp--height comparator. Tyco

Electronics does not manufacture or market

crimp--height comparators. Detailed information on

obtaining and using crimp--height comparators can be

found in instruction sheet 408--7424.

Proceed as follows:

1. Refer to Figure 4 and select a wire (maximum

size) for each crimp section listed.

2. Refer to Section 5, CRIMPING PROCEDURE,

and crimp the contact(s) accordingly.

3. Using a crimp height comparator, measure the

wire barrel crimp height as shown in Figure 4. If the

crimp height conforms to that shown in the table,

the tool is considered dimensionally correct. If not,

the tool must be adjusted. Refer to Section 7,

RATCHET ADJUSTMENT.
