jaw and through both anvil dies, and tighten the
screw just enough to hold the dies in place. Do
not
tighten the screw completely at this time.
5. Place the wire crimper and insulation crimper
so that their chamfered sides and their marked
surfaces face outward, when mounted in the
stationary jaw of the tool frame.
6. Insert the two die retaining pins.
7. Insert the long die retaining screw through the

not
tighten the screw completely at this time.
8. Carefully close the tool handles, making sure
that the anvils and crimpers align properly.
Continue closing the tool handles until the ratchet
in the tool frame has engaged sufficiently to hold
the anvils and crimpers in place, then tighten both
die retaining screws.
9. Place the locator assembly over the end of the
long screw, and position the locator assembly
against the side of the tool jaw.
10. Place the nut onto the end of the long screw
and tighten the nut enough to hold the locator
assembly in place, while still allowing the locator to

11. To disassemble, close the tool handles until the
ratchet releases, remove the nut, the locator
assembly, the two die retaining screws, and the
four die retaining pins, and slide the anvils and
crimpers out of the tool jaws
2. DESCRIPTION
(Figures 1 and Figure 2)
The tool features a tool frame with a stationary jaw
and handle, a moving jaw, a moving handle, and an
adjustable ratchet that ensures full contact crimping.
The tool frame holds a die assembly with two
crimping sections.
The die assembly features a wire anvil, an insulation
anvil, a wire crimper, and an insulation crimper.
Attached to the outside of the frame is a locator
assembly, which contains a locator, a spring retainer,
and a contact support.
Attached to the opposite side of the frame is a
hold--down, which locates the wire in the correct
position before crimping.
Die retaining pins and die retaining screws are used
to position and secure the dies in the tool frame. A
nut is used on the upper die retaining screw to hold
the locator assembly in place.
3. INSTALLATION AND REMOVAL OF DIE SET
AND LOCATOR ASSEMBLY
(Figure 2)
1. Open the tool handles and remove the two die
retaining screws from the tool jaws.
2. Place the wire anvil and insulation anvil so that
their chamfered sides and their marked surfaces
face outward, when mounted in the moving jaw of
the tool frame.
3. Insert the two die retaining pins.

contact is still being bent during crimping, repeat
the adjustment procedure.
i
5. CRIMPING PROCEDURE
NOTE
1. Make a sample crimp and determine if the
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
The ratchet has detents that create audible clicks
as the tool handles are closed.
i
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 (Crimp Height)
ADJUSTMENT, to verify crimp height before
using the tool to crimp desired contacts and wire
sizes.
i
3. Place a contact with wire into the proper nest
and close the tool handles until the ratchet reaches
the sixth click, or until the contact support touches
the contact.
4. Slightly loosen the nut that holds the locator
assembly onto the tool frame.
5. Move the contact support as required to
eliminate the bending of the contact.
6. Tighten the nut and close the handles until the
ratchet releases.
7. Remove and inspect the contact.
8. Make another sample crimp. If the contact is
straight, tighten the contact support screw. If the

Locator
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.
3. Position the contact so that the mating end of
the contact is on the locator side of the tool, and so
that the open “U” of the wire and insulation barrels
face the top of the tool. Place the contact up into
the nest so that the movable locator drops into the
slot in the contact. Refer to Figure 3. Butt the front
end of the wire barrel against the movable locator.

CAUTION
Make sure that both sides of the insulation barrel
are started evenly into the crimping section. Do
NOT attempt to crimp an improperly positioned
contact
wheel COUNTERCLOCKWISE to a
higher--numbered setting. If a looser crimp is
required, rotate the adjustment wheel
CLOCKWISE to a lower--numbered setting.
!
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
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 (Crimp Height)
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.
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.

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

8. MAINTENANCE
Ensure that the tool and dies are clean by wiping
them with a clean, soft cloth. Remove any debris with
a clean, soft brush. Do not use objects that could
damage the tool. When not in use, keep handles
closed to prevent objects from becoming lodged in
the crimping dies, and store in a clean, dry area.

and springs.
If the dies are damaged or worn excessively, they
must be replaced.

9. VISUAL INSPECTION
The crimping dies should be inspected on a regular
basis to ensure that they have not become worn or
damaged. Inspect the crimp sections for flattened,
chipped, worn, or broken areas. If damage or
abnormal wear is evident, the tool must be replaced.
See Section 10, REPLACEMENT.
