3. Position the contact so that the mating end is on
the locator side of the tool, and so that the open
“U” of the insulation barrel faces the stationary jaw.
Place the contact up into the crimping chamber so
that the locator drops into the wire stop slot in the
contact. Refer to Figure 3. Butt the end of the
contact against the locator.
Make sure that both sides of the insulation barrel
are started evenly into the crimping chamber. Do
NOT attempt to crimp an incorrectly positioned
contact.
4. Hold the contact in place and squeeze the tool
handles together until ratchet engages sufficiently
to hold the contact in position. Do NOT deform the
insulation barrel or wire barrel.
5. Insert stripped wire into contact insulation barrel
until it is butted against the wire stop as shown in
Figure 3.
6. Holding wire in place, squeeze tool handles
together until ratchet releases. Allow tool handles
to open then remove crimped contact.
The crimped contact may stick in the crimping
chamber. It can be easily removed by pushing
downward on the top of the locator. Refer to
Figure 3.
7. Inspect the crimped contact to ensure that the
crimp is centered on the wire barrel and that the
wire is fully inserted. Check the crimp height as
described in Section 6. If necessary, adjust the
crimp height as described in Section 7.
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. 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 for each
crimping chamber listed.
2. Refer to Section 5, CRIMPING PROCEDURE,
and crimp the contacts 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, the tool is
considered dimensionally correct. If not, the tool
must be adjusted. Refer to Section 7, RATCHET
ADJUSTMENT.
7. RATCHET ADJUSTMENT (Figure 5)
1. Remove the lockscrew from the ratchet
adjustment wheel.
2. With a screwdriver, adjust the ratchet wheel
from the front 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
