TE Connectivity PRO-CRIMPER III Manual page 5

Make sure that both sides of the insulation barrel
CAUTION
are started evenly into the crimping section. Do
NOT attempt to crimp an improperly positioned
!
contact.
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 the ratchet releases. Allow the tool
handles to open and remove crimped contact.
The crimped contact may stick in the crimping area,
NOTE
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. Tyco
Electronics does not manufacture or market crimp--
height comparators. Detailed information on obtaining
and using crimp--height comparators can befound 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.
7. RATCHET ADJUSTMENT
1. Remove the lockscrew from the ratchet
adjustment wheel. See Figure 5.
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.
