2. Insert a die retention screw through the jaw and
die, and tighten the screw so that the die is held in
place, but that the screw is not completely tighten at
this point.
NOTE
2. Insert the die retaining pins and the short die
retention screw. Do not tighten the screw
completely.
3. Install the wire and insulation crimper dies with
the chamfers facing the front of the tool and the die
markings facing outward into the stationary jaw of
the tool frame.
4. Insert the die retaining pins and the long die
retention screw. Do not tighten the screw
completely.
5. Slowly close the tool handles, allowing the dies to
mate and/or align. Continue closing the tool handles
until the ratchet makes the sixth "click," then tighten
both die retention screws until snug.
NOTE
i
Install die assemblies with center contact crimping
chamber with the center contact crimp chamber
toward the front of the tool jaws as shown in
Figure 2. If indicated otherwise in another
document, follow the specific die requirements
demonstrated in that document.
3. Place the lower die in the moving jaw of the tool
frame. Install a die retention screw through the jaw
and die, and tighten the screw so that the die is held
in place, but that the screw is not completely tighten
at this point.
4. Slowly close the tool handles, allowing the dies to
mate and/or align. Continue closing the tool handles
until the ratchet makes the sixth "click," then tighten
both die retention screws until snug.
NOTE

The tool ratchet has detents that are audible in
seven "clicks" as the handles are closed. The
ratchet releases on the seventh "click".

6. Install the locator assembly and tighten the hex
nut.
7. Reverse these steps to remove the die assembly.
5. To remove the die assembly, close the tool
handles until the ratchet releases, and allow the
handles to open fully. Loosen and remove the die
retention screws and slide the dies out of the tool
jaws.
4. CRIMP HEIGHT ADJUSTMENT
The tool frame features a ratchet mechanism and
adjustment wheel with a range of settings. The ratchet
mechanism ensures that the tool has completed the
cycle. The adjustment wheel controls the amount of
handle pressure exerted on the jaws and dies during
the crimping procedure. Although the ratchet is preset
prior to shipment, it is important that the crimp height
be verified. Also, general use and subsequent wear
may cause the tool to go out of adjustment.
3.2. Pinned Dies
(See Figure 3)
1. Install the wire and insulation anvil dies with the
chamfers facing the front of the tool and the die
markings facing outward into the movable jaw of the
tool frame.

It is recommended that the crimp height be inspected
and adjusted, if necessary, on a regular basis by
quality control personnel.
NOTE
5.3. Periodic Inspection
Regular inspections of the tool should be performed
by quality control personnel. A record of scheduled
inspections should remain with the tool or be supplied
to personnel responsible for the tool. Inspection
frequency should be based upon amount of use,
working conditions, operator training and skill, and
established company standards.
1. Remove all lubrication and accumulated film by
immersing the tool (handles partially closed) in a
suitable commercial degreaser that will not affect
paint or plastic material.
2. Make certain that all pivot pins are in place and
secured with retaining rings.
3. Close the tool handles until the 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 Paragraph 6,
REPLACEMENT AND REPAIR.
4. Inspect the tool frame for wear or damage,
paying particular attention to the jaws and pivot
points. If damage is evident, refer to Paragraph 6,
REPLACEMENT AND REPAIR. If tool is
acceptable, lubricate it, and return it to service.
i
This is a general explanation of the adjustment.
For specific information, refer to the instruction
sheet packaged with the die assembly.
1. Crimp a connector onto a properly-prepared wire
of correct size.
2. If the crimp height is greater than recommended,
remove the ratchet wheel adjustment screw and
rotate the adjustment wheel COUNTERCLOCKWISE
to a higher setting. Repeat as required.
If the crimp height is less than recommended,
remove the ratchet wheel adjustment screw and
rotate the adjustment wheel CLOCKWISE to a
lower setting. Repeat as required.
If the crimp cannot be made to conform to the
dimensions provided in the applicable product
application specification, the tool and/or dies are
defective and must be replaced.
5. MAINTENANCE AND INSPECTION
5.1. Initial Inspection
PRO-CRIMPER III Hand Crimping Tool Frame
Assembly 354940-1 is inspected prior to shipment.
It is recommended that it be inspected upon arrival to
ensure that it has not become damaged during
shipping.
6. REPLACEMENT AND REPAIR
Available separately, Repair Kit 679221-1 includes a
replacement nut and a variety of pins, rings, screws,
and springs. Refer to Figure 4 to determine the item to
be replaced and identify the proper location and
orientation of the part in the tool frame. If the dies are
damaged or worn excessively, they must be replaced.

5.2. Daily Maintenance
It is recommended that operators of the tool be made
aware of, and responsible for, the following steps of
daily maintenance:
1. Remove dust, moisture, and any other
contaminants from the tool with a clean, soft brush,
or a clean, soft, lint-free cloth. Do NOT use hard or
abrasive objects that could damage the tool.
2. Make certain that the pivot 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
