4. Hold the contact in position and squeeze the tool
handles together until ratchet engages sufficiently to
hold the contact in position. Do NOT deform
insulation barrel or wire barrel.
5. Insert stripped wire into contact insulation and
wire barrels until it is butted against the wire stop, as
shown in Figure 3.
6. Holding the wire in place, squeeze tool handles
together until ratchet releases. Allow tool handles to
open and remove crimped contact.
NOTE
i
The crimped contact may stick in the crimping area,
but the contact can be easily removed by pushing
downward on the top of the locator (see Figure 3).
7. Check the contact's crimp height as described in
Section 6, Crimp Height Inspection. If necessary,
adjust the crimp height as described in Section 7,
RATCHET ADJUSTMENT.
6. 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. TE 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 (Crimp Height) ADJUSTMENT.
7. RATCHET (Crimp Height) ADJUSTMENT (Figure 5)
1. Remove the lockscrew from the ratchet
adjustment wheel.
2. With a screwdriver, adjust the ratchet wheel from
the locator side of the tool.

3. Observe the ratchet adjustment wheel. If a tighter
crimp is required, rotate the adjustment wheel
COUNTERCLOCKWISE to a higher-numbered
setting. If a looser crimp is required, rotate the
adjustment wheel CLOCKWISE to a lower-
numbered setting.
4. Replace the lockscrew.
5. Make a sample crimp and measure the crimp
height. If the dimension is acceptable, replace and
secure the lockscrew. If the dimension is
unacceptable, continue to adjust the ratchet, and
again measure a sample crimp.
