1. INTRODUCTION
2. DESCRIPTION
The head assembly, when properly inserted into the
tool, serves as a guide for the connector during
termination.
The 2 mm CT Head Assembly 58372--1 shown in
Figure 1 is designed to terminate the connectors onto
unstripped discrete wire sizes listed in Figure 1.
Features of the head assembly (shown in Figure 1)
and their functions are:
The head is designed for use in Pistol Grip Manual
Handle Assembly 58074--1 (408--6790), Pistol Grip
Pneumatic Handle Assembly 58075--1 (408--6789), or
Pneumatic Power Bench Assembly 58338--1
(408--9393). For head installation procedures, and
setup and operation of the tools, refer to the
instruction sheets (shown in parenthesis) packaged
with the tool.
Wire Inserter—forces unstripped wire into the two
slotted beams of the contact.
Wire Insertion Rod and Adjuster—acts as a piston
for, and regulates travel of, the wire inserter.
Carriage—slides right and left in head assembly
and automatically advances the connector after
each termination.
Dimensions on this sheet are in metric units [with
U.S. customary units in brackets]. Figures and
illustrations are for reference only and are not
drawn to scale.
NOTE
Drag—prevents connector from moving out of
position after it has been advanced.

3. Push the feed pawl forward and slide the
carriage (with connector) to the right as far as it will
go. Then release the feed pawl. The connector is
now in position to begin termination.
Wire Guide—open channel into which unstripped
wire is inserted and bottomed for terminating.
Feed Pawl—when pushed forward, allows carriage
to be moved either right or left, depending on
where connector is to be located in head assembly.
4. TEST TERMINATION AND INSPECTION
At least one termination should be performed and
inspected before starting production terminating. The
steps which follow are recommended to perform the
test termination and inspection.
The wire is terminated in the connector contact using
the insulation displacement technique (a terminating
technique which inserts unstripped wire into a slotted
contact beam to form a reliable electrical connection
between the wire and the contact). Contact
termination is complete when the tool is actuated.

3. SETUP
The setup procedure consists of determining the size
of the connector slot, securing the connector in that
slot, and positioning the connector for termination.
Proceed as follows:

1. To determine the size of slot required for the
connector to be terminated, push the feed pawl
forward and slide the carriage to the left as far as it
will go. Then loosen the socket head cap screw
located at bottom side of the adjustable stop
(shown in Figure 2), allowing the stop to be moved
right or left.

2. Without inserting the wire into the wire guide,
perform one cycle. The connector will be indexed

3. Insert an unstripped wire into the wire guide until
the wire bottoms, making sure wire is centered in
the slot. See Figure 4.
2. Orient the connector with the head assembly as
shown in Figure 3 — the open part of the insulation
displacement slot is up and facing the back of the
tool. Making sure that the connector slot is large
enough to accept the connector, fit the connector
in slot. Then move the adjustable stop flush

6. Inspect termination in accordance with
Application Specification 114--5103. If wire
insertion depth is incorrect or if the carriage is not
feeding properly, refer to Section 5.
2. If the proper wire insertion depth is not obtained,
set the air pressure to 276 kPa [40 psi], and follow
the procedure in Paragraph 5.1, A.
5.2. Carriage Feed
5. ADJUSTMENTS
The carriage feed adjustment setscrew, shown in
Figure 6, controls the location of the carriage. If the
screw is positioned in too far, the feed pawl will not
engage in the carriage and the carriage will not
advance. If the screw is out too far, the carriage will
back up until the feed pawl engages, and thus, will
incorrectly position the contact to be terminated.
Adjust the carriage by turning the adjustment screw
either in or out until the contact aligns with the wire
inserter.
5.1. Wire Insertion Depth (See Figure 5)
A. For Pistol Grip Manual Handle Assembly
If the wire is too deep in the contact insulation
displacement slot, remove the head from the tool and
turn the adjuster 1/6-- r e v o l u t i o n clockwise. This will
reduce the wire insertion depth by approximately
0.20 mm [.008 in.]. Install the head onto the tool; then
terminate and inspect a sample connector.
If the wire is not deep enough in the contact insulation
displacement slot, remove the head from the tool and
turn the adjuster 1/6-- r e v o l u t i o n counterclockwise. This
will increase the wire insertion depth by approximately
0.20 mm [.008 in.]. Install the head onto the tool; then
terminate and inspect a sample connector.

3. Actuate the tool to ensure that mechanisms
inside the head assembly move smoothly.

7.2. Periodic Inspection
: no movement of the connector housing occurs
Regular inspections should be be performed by
quality control personnel. A record of scheduled
inspections should remain with the head assembly or
be supplied to supervisory personnel responsible for
the head assembly. Though recommendations call for
at least one inspection a month, the inspection
frequency should be based on the amount of use,
ambient working conditions, operator training and
skill, and established company standards. These
inspections should include a visual inspection and
should be performed in the sequence listed.

6. TERMINATION PROCEDURE
1. Select the applicable connector and wire to be
terminated.
2. Perform the setup procedure as described in
Section 3. Note that at the end of this procedure
the connector is in position to begin the termination
process.
1. Remove any accumulated film with a suitable
commercial degreaser that will not affect paint or
plastic material.
3. Without inserting the wire into the wire guide,
perform one cycle. The connector will be indexed
in position for the first termination.
2. Make sure all components are in place and are
properly secured.
4. Insert an unstripped wire into the wire guide until
the wire bottoms, making sure wire is centered in
the slot.
3. Make a few test terminations and inspect the
terminations in accordance with 114--5103.
4. Check for chipped, cracked, worn, or broken
areas. If damage is evident, repair is necessary.
See Section 8.
5. Perform one termination cycle: the inserter will
bottom, forcing the wire between the contact slots,
and will then retract. The connector will advance to
the next contact position.
6. Continue to insert unstripped wire and cycle the
tool until all contacts of the connector are
terminated.
8. REPLACEMENT AND REPAIR
Customer--replaceable parts are listed in Figure 7.
A complete inventory should be stocked and
controlled to prevent lost time when replacement of
parts is necessary. Parts other than those listed
should be replaced by TE Connectivity to ensure
quality and reliability. Order replacement parts
through your TE Representative, or call
7. Remove the connector from the left side of the
carriage.
8. Repeat these steps until all connectors are
terminated.
