PROPER USE GUIDELINES
Cumulative Trauma Disorders can result from the prolonged use of manually powered hand tools. Hand tools are intended for occasional use and low volume
applications. A wide selection of powered application equipment for extended-- use, production operations is available.
2. DESCRIPTION
The tool (shown in Figure 1) features two sets of
crimping dies and a CERTI--CRIMP ratchet.
One die set crimps the cable center conductor and
the splice lead conductor in a parallel splice; and the
other set crimps the cable braid and ground wire
conductor together in a parallel braid splice. Both
crimps are simultaneously accomplished with one
operating cycle of the tool.

Dies
The CERTI--CRIMP ratchet ensures full crimping of
the splice. Once engaged, the ratchet will not release
until the handles have FULLY closed.
CAUTION
CERTI-- CRIMP*

!
The crimping dies bottom before the
CERTI--CRIMP tool ratchet releases. This design
feature ensures maximum electrical and tensile
performance of the crimp. Do NOT re--adjust the
ratchet.

NOTE

Figure 1
1. INTRODUCTION
Hand Crimping Tools 69156--1 and 69241--1, see
Figure 1, are designed to crimp TERMASPLICE*
splices on coaxial or shielded cables within a primary
insulation diameter range as listed in Figure 2. Splice
lead and ground wire sizes 24 through 20 AWG are
simultaneously crimped in the splice with the shielded
or coaxial cable. Read these instructions thoroughly
before using the tools.
Reasons for reissue of this document are provided in
Section 6, REVISION SUMMARY.
NOTE
i
Dimensions on this sheet are in millimeters [with
inches in brackets].
Each hand tool is coated with a preservative to
prevent rust or corrosion. Wipe this preservative
from the tool, particularly from the crimping jaws,
before using the tool.
The crimping procedure requires two separate
operations. First, the cable and wires must be
prepared and assembled in the splice; then the entire
assembly is crimped using the hand tool.
3.1. Cable / Wire Preparation and Assembly
Select the proper cable, splice lead, and ground wire
and strip to the dimensions shown in Figure 2. Then
refer to Figure 3, and proceed as follows:
1. Slightly twist the cable center conductor strands.
2. Flare the cable braid so that it will easily slide
over the support sleeve of the splice.
3. Carefully insert cable into splice so that the
center--conductor insulation passes through the
support sleeve and the braid passes over and
around the support sleeve. Continue to insert cable
until the stripped center conductor enters parallel
splice area and insulator bottoms in support
sleeve.

5. While holding ground wire and cable securely in
place, insert splice lead into parallel splice area.
Make certain that splice lead does not move or
bend the cable center conductor. Parallel splice
area will accept solid or stranded wire sizes 24
through 20 AWG.

To crimp the splice assembly, refer to Figure 4 and
proceed as follows:
1. Open the tool’s crimping dies by squeezing the
handles until the ratchet releases and then allow
the handles to open FULLY.
2. Position the splice assembly in the splice and
braid crimping dies, as shown in Figure 4. Small
shoulder on tapered end of splice should butt
against lower splice crimping die.
NOTE
Make certain that section of splice containing
ground wire faces upper braid die.

3. Slowly squeeze tool handles until splice body is
held firmly in place.
4. While holding cable and wires in place, continue
to close tool handles until ratchet releases. Allow
handles to open FULLY and remove crimped
splice.
4. MAINTENANCE AND INSPECTION PROCEDURE
Tyco Electronics recommends that a maintenance
and inspection program be performed periodically to
ensure dependable and uniform terminations.
Frequency of inspection depends on:
1. The care, amount of use, and handling of the
hand tool.
2. The presence of abnormal amounts of dust and
dirt.
3. The degree of operator skill.
4. Your own established standards.
The hand tool is inspected before being shipped;
however, it is recommended that the tool be inspected
immediately upon its arrival at your facility to ensure
that the tool has not been damaged during shipment.
Due to the precision design, it is important that no
parts of these tools be interchanged except those
replacement parts listed in Figure 7.
Rev L
4.1. Daily Maintenance
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 certain that the retaining pins are in place
and that they are secured with retaining rings.
3. All pins, pivot points, and bearing surfaces
should be protected with a thin coat of any good
SAE 20 motor oil. Do not oil excessively.
4. When the tool is not in use, keep handles closed
to prevent objects from becoming lodged in the
crimping dies. Store the tool in a clean, dry area.
4.2. Lubrication
Lubricate all pins, pivot points, and bearing surfaces
with SAE 20 motor oil as follows:
Tools used in daily production -- lubricate daily
Tools used daily (occasional) -- lubricate weekly
Tools used weekly -- lubricate monthly
Wipe excess oil from tool, particularly from crimping
area. Oil transferred from the crimping area onto
certain terminations may affect the electrical
characteristics of an application.
4.3. Periodic Inspection
1. Hand tool should be immersed (handles partially
closed) in a reliable commercial degreasing
compound to remove accumulated dirt, grease,
and foreign matter.

2. Close tool handles until ratchet releases and
then allow them to open freely. If they do not open
quickly and fully, the spring is defective and must
be replaced. See Section 5, REPLACEMENT AND
REPAIR.
3. Align the GO element of the proper plug gage
with the braid crimp section. Push element straight
into the crimp section without using force. The GO
element must pass completely through the crimp
section.
3. Inspect head assembly for worn, cracked, or
broken dies. If damage is evident, return the tool
for evaluation and repair. See Section 5,
REPLACEMENT AND REPAIR.
4. Check the braid crimp section with the NO--GO
element in the same manner as step 3. The
GO--GO element may start entry, but must not
pass completely through the crimp section.
5. Check the splice crimp section by repeating
Steps 3 and 4 using the proper plug gage.
4.4. Crimping Die Closure Inspection
This inspection requires the use of two plug gages
conforming to the dimensions shown in Figure 5. Tyco
Electronics does not manufacture or market these
gages.
To gage die closure, refer to Figure 6 and proceed as
follows:
1. Remove traces of oil or dirt from the crimping
chamber and plug gage.
If die closures conforms to the gage inspections, the
crimp sections are considered dimensionally correct.
If correct, the tool should be lubricated with a thin
coat of any good SAE 20 motor oil and returned to
service. If not correct, the tool must be returned for
further evaluation and repair. Refer to Section 5,
REPLACEMENT AND REPAIR. For additional
information regarding the use of a plug gage, refer
to instruction sheet 408--7424.
4.5. CERTI- CRIMP Ratchet Inspection
2. Close the tool handles until it is evident that the
dies have bottomed; then hold in this position. Do
NOT force the dies beyond initial contact.
The CERTI--CRIMP ratchet feature on Tyco
Electronics hand tools should be checked to ensure
that the ratchet does not release prematurely,
