1. INTRODUCTION
This instruction sheet covers operation and
maintenance of MTA Terminating Head 58246–1 for
use in Pistol Grip Manual Handle Assembly 58074–1,
or Pistol Grip Pneumatic Handle Assembly 58075–1.
Read these instructions thoroughly before using the
heads. Refer to the instructions packaged with the
pistol grip handle assembly for head installation and
removal: Instruction Sheet 408–6790 (manual) and
Instruction Sheet 408–6789 (pneumatic).
Add dimensions on this instruction sheet are in
millimeters [with inches in brackets]. Figures are
for reference only and are not drawn to scale.
See Section 8, REVISION SUMMARY, for revision
information.
2. DESCRIPTION
This head is used to terminate unstripped wires in two
types of MTA–100 closed–end receptacle assemblies:
connectors with lock (ramp), and connectors with
polarizing tabs and lock. Slotted contacts for
insulation displacement termination are pre–
assembled on 2.54 [.100] centerlines in each
color–coded housing for a specific wire size. Refer to
Figure 2 and to Application Specification 114–1019 for
further details.
The head, which is inserted into the pistol grip handle
assembly, serves as a guide and support for the
connector during termination. Features of the head
(shown in Figure 1) and their functions are as follows:
Wire Inserter – forces wire into the two slotted beams
of the contact. Note that it provides support for the
contact beams when applying insertion force on the
wire.
Adjuster (Insertion Rod) – is a piston for the wire
inserter and regulates wire inserter travel.
Feed Slide – automatically positions the connector
after each termination.
Locating Pawl – aligns connector for insertion, and
retains it during termination. The locating pawl is
sometimes referred to as the “anti–backup pawl.”
3. SETUP ADJUSTMENTS AND TEST
The adjuster (insertion rod) of the wire inserter is
preset for wire sizes 22 through 28 AWG. If the wire
is being inserted too deeply or not deeply enough
inside the contact, it may be necessary to adjust the
depth of the wire inserter; or, if the pneumatic handle
assembly is being used, it may be necessary to adjust
either the air pressure or the depth of the wire
inserter.
3.1. For Pistol Grip Manual Handle Assembly
1. Determine the wire size, and select the
appropriate color–coded connector from the chart
in Figure 2. Dash numbers are used to indicate
number of contact positions.
2. Using a small knife, cut off the wire retainers
(strain relief). This will provide a clear view for
inspecting the connector for a properly terminated
wire in the contact. See Figure 3.

Wire retainers are removed to provide a
connector for testing only. Do NOT use such
connectorsforproductionapplications.
3. . Place connector in tool and make a test
termination using the procedures described in
Section 4, TERMINATING PROCEDURE, Steps 1
through 6.
4. Push connector out of right side of head.
5. Inspect termination in accordance with Section
5, INSPECTION, Steps 1 through 6.
If you determine that the wire insertion depth is
incorrect, proceed to Paragraph 3.3, Wire Insertion
Depth Adjustment.
3.2. For Pistol Grip Pneumatic Handle Assembly
1. Perform the procedure outlined in Paragraph
3.1, For Pistol Grip Manual Handle Assembly,
Steps 1 through 4.
2. Inspect termination to ensure that conductor is
terminated past the lead–in transition and is
positioned about halfway into the contact slot. See
Figure 3.

NOTE: 1/6 turn equals 0.20 [.008] adjustment.
3. Inspect termination to ensure that insulation is
1.02 [.040] minimum beyond the front contact
beam.
4. If, upon inspection, it is determined that the wire
is not inserted deeply enough, increase the air
pressure by 69 kPa [10 psi], and repeat the
termination and inspection procedure. Continue in
this manner until either the proper insertion depth
is obtained or the air pressure is set to 483 kPa
[70 psi]. If the proper insertion depth is NOT
reached at 483 kPa [70 psi], return the air pressure
to 276 kPa [40 psi] and follow the procedure in
Paragraph 3.3, Wire Insertion Depth Adjustment.
5. If the wire is inserted too deeply, refer to the
procedure in Paragraph 3.3, Wire Insertion Depth
Adjustment.
3.3. Wire Insertion Depth Adjustment
Wire Too Deep in Contact Slot – If the wire is inserted
too deeply, remove the head, and turn the adjuster
1/6 revolution CLOCKWISE (see Figure 4). This will
reduce the wire insertion depth by approximately 0.20
[.008]. Repeat Steps 3, 4, and 5 of Paragraph 3.1, for
Pistol Grip Manual Handle Assembly.
Wire Not Deep Enough in Contact Slot – If the wire is
not inserted deeply enough in contact slot, remove
the head and turn the adjuster 1/6 revolution
COUNTERCLOCKWISE (see Figure 4). This will
increase the wire insertion depth by approximately
0.20 [.008]. Repeat Steps 3, 4, and 5 of Paragraph
3.1, (or Steps 3 and 4 of Paragraph 3.2).
4. TERMINATING PROCEDURE (Figure 5)
1. Insert connector into left side of head as
indicated.
2. Align contact to be terminated with wire inserter.
3. Make sure locating pawl rests between
connector index ribs.
4. Insert an unstripped wire into the funnel area
between contact and wire inserter until it bottoms
on tool base.
5. Depress trigger (or squeeze cam handle) of
pistol grip handle assembly and hold it until inserter
bottoms or ratchet releases.
6. Release trigger (or cam handle). The inserter
will retract and the feed slide will automatically
advance connector to next contact position.

The locating pawl will move up and down as the
connectoris automatically advanced throughthe
head. However, if movement is obstructed, or if
desirable, the locating pawl can be depressed
and the connector moved manually out the
RIGHT side of the head.
7. Repeat Steps 2 through 6 until all contacts have
been terminated.
8. Inspect each termination according to the
procedure in Section 5, INSPECTION.
5. INSPECTION (Figure 3)
Inspect each termination to ensure the following:
1. Conductor is terminated past the lead–in
transition and about halfway in the contact slot.
2. Insulation is 1.02 [.040] minimum beyond the
front contact beam. See Figure 3.
3. Wire is NOT bottomed in contact slot.
4. Contact beams are NOT deformed. If damage is
apparent, replace contacts in accordance with the
instructions packaged with the connector.
5. Insulation of wire is NOT nicked or cut in any
area other than the two wire slots.
6. Wire extends below the strain–relief features of
connector.
6. TOOL MAINTENANCE
The procedures described in the following text have
been established to assure quality and reliability of
terminating tools. A brief check should be made daily,
and a more detailed inspection should be scheduled
by your quality control group.
6.1. Daily Maintenance
Each operator should be aware of, and responsible
for, the following:
1. Remove dust, moisture, and other contaminants
with a clean brush, or a soft, lint–free cloth. Do
NOT use objects that could damage the tool.
2. Make sure all components are in place and
properly secured. (If NOT, return the tool to your
supervisor.)
3. Actuate handle assembly to ensure
mechanisms inside head move smoothly.
6.2. Periodic Maintenance
Regular inspections should be performed by your
quality control personnel with a record of these
inspections remaining with the personnel responsible
for the tool. We recommend one inspection a month;
however, operator training and skill, amount of use,
ambient working conditions, and your company’s
established standards are all factors in establishing
frequency of inspections.
These inspections should be done in the following
sequence:
1. Remove any accumulated film with a suitable
cleaning agent that will NOT affect plastic material.
2. Make sure all components are in place and
properly secured. See Figure 6.
3. Make a few test terminations and inspect the
terminations in accordance with Section 5,
INSPECTION.
4. Check for chipped, cracked, worn, or broken
areas. If damage is evident, repair is necessary.
See Section 7, REPLACEMENT AND REPAIR.
7. REPLACEMENT AND REPAIR
The parts listed in Figure 6 are customer–
replaceable. A complete inventory can be stocked
and controlled to prevent lost time when replacement
of parts is necessary. Order replacement parts
through your TYCO ELECTRONICS Representative,
or call 1–800–526–5142, or send a facsimile of your
purchase order to 1–717–986–7605. or write to:
