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.

1. INTRODUCTION
This instruction sheet covers the use and maintenance
of Crimping Dies 58425-[ ] and58436-[ ] (in their
various configurations - denoted by the dash number
following the base part number), used in PRO-
CRIMPER III Hand Tool Frame 354940-1. The dies
crimp 75-Ohm Hex Crimp BNC and TNC plug
connectors onto coaxial cable.
Reasons for reissue of this sheet are provided in
Section 7, REVISION SUMMARY.
NOTE
i
All dimensions are in millimeters [with inches in
brackets]. Figures and illustrations are for
reference only and are not drawn to scale.

2. DESCRIPTION (Figure 1)
Each die assembly consists of an indenter die and an
anvil die. When closed, the dies form either two or
three crimping chambers (depending on type) which
crimp the center contact and ferrule of the connector
onto the coaxial cable. Each die is held in the tool by a
single screw.
3. DIE INSTALLATION
1. Close the tool handles until the ratchet releases
and then allow them to open fully.
2. See Figure 1 for normal orientation of the dies.
Insert the dies inside the tool jaws and align the
retaining screw holes.
3. Thread the retaining screws into the holes and
carefully close the tool handles. Tighten the screws
with the appropriate hex wrench.

4. CRIMPING PROCEDURE
4.1. Center Contact
1. Prepare the connector and the cable according to
the instructions packaged with the connector.
2. Slide the center contact onto the center
conductor of the cable; then insert the contact
assembly into the center contact crimp section of
the die. See Figure 2.
NOTE
i
Make sure that the flange on the end of the center
contact butts against the crimping die. See

Figure 3.
3. Crimp the center contact by holding the cable in
place; then close the tool handles until the ratchet
releases.
4.2. Ferrule
1. Insert the crimped center contact into the
connector body until the cable dielectric butts
against the dielectric inside of the connector body.
The flared braid will then fit around the support
sleeve of the connector body.
2. Slide the ferrule forward over the braid until the
ferrule butts against the shoulder on the connector
body.
3. Place the ferrule on the appropriate anvil of the
die assembly so that the shoulder on the connector
body is butted against the die. See Figure 4.
4. Holding the assembly in place, close the tool
handles until the ratchet releases.

CAUTION
!
Damaged product should not be used. If a
damaged contact or ferrule is evident, it should be
cut from the wire and replaced with a new one. Do
NOT reterminated contact or ferrules.
5. INSPECTION
5.1. Visual Inspection
Inspection of the crimping dies should be made 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 dies must be
replaced. Refer to Section 6, PARTS REPLACEMENT.

5.2. Measuring Die Opening
The die assembly will perform correctly as long as: 
(1) the product specified is correct for the application,
(2) the specific die assembly is used, (3) the die
assembly has been measured to ensure that the
openings are correct, and (4) the tool has been
adjusted correctly.
Figure 5 provides information on die opening sizes.
5.3. Ratchet Adjustment
The tool frame assembly ratchet mechanism features
an adjustment wheel with eight settings. The
adjustment wheel controls the amount of handle
pressure exerted on the tool jaws and crimping dies
during crimping. If the crimp is not acceptable, adjust
the ratchet as follows:
1. Sufficiently loosen the screw at the ratchet
adjustment wheel so that the wheel can be rotated
above the post that engages the teeth in the wheel.
2. If the crimp is too loose, turn the wheel to a
higher notch (for example, if the wheel is set at
notch no. 5, move the wheel to notch no. 6). If the
crimp is too tight, move the wheel to a lower notch.
3. Tighten the screw at the ratchet adjustment
wheel.
If the crimp cannot be made to conform to the
dimensions provided in the appropriate product
application specification, the tool and/or dies are
defective and must be replaced.
NOTE
i
Other dies of the PRO-CRIMPER hand tool series
may be used in this tool; however, the ratchet
adjustment wheel may require adjustment to
achieve acceptable crimp height.
6. PARTS REPLACEMENT
Customer-replaceable parts are shown in Figure 1.
Available separately, epair Kit 679221-1 includes a
variety of pins, rings, screws, and springs. If the dies
are damaged or worn excessively, they must be
replaced. Order the repair kit and replaceable parts
through your TE Representative, or call 1-800-526-
5142, or send a facsimile of your purchase order to 1-
