1. INTRODUCTION
This instruction sheet provides application and maintenance procedures for PRO-CRIMPER III Hand Crimping
Tool Frame Assembly 354940-1, shown in Figure 1. The tool is designed to accept interchangeable die
assemblies for crimping various types of products.
NOTE
In most cases, the tool frame assembly is provided with a specific set of dies and is considered a component part of a
crimping assembly. Refer to the appropriate instruction sheet packaged with the hand tool and die assembly or with the
separate die assembly for information regarding crimping procedures, crimp height inspection, and die gaging.
Read these instructions thoroughly before installing dies and using the tool frame.
Reasons for reissue of this instruction sheet are provided in Section 7, REVISION SUMMARY.
2. DESCRIPTION
The tool frame consists of two crimping jaws, an adjustable ratchet, spring-actuated handles, two die retaining
screws, and an emergency ratchet release. The slotted design of the tool jaws permits easy installation and
removal of dies. The adjustable ratchet allows handle pressure to be set for optimum die performance.
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.

3. DIE INSTALLATION AND REMOVAL
Select the desired die assembly, remove the die retention screws from the tool jaws, and proceed as follows:
3.1. Shouldered Dies (See Figure 2)
1. Place the upper die in the stationary jaw of the tool frame.
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
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 seventh "click," then tighten both die retention screws until snug.
NOTE
The tool ratchet has detents that are audible in eight “clicks” as the handles are closed. The ratchet releases on the eighth
“click”.
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.
Figure 2
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.
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 seventh “click”, then tighten both die retention screws until snug.
NOTE
The tool ratchet has detents that are audible in eight “clicks” as the handles are closed. The ratchet releases on the eighth
“click”.
6. Install the locator assembly and tighten the hex nut.
7. Reverse these steps to remove the die assembly.
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.
It is recommended that the crimp height be inspected and adjusted, if necessary, on a regular basis by quality
control personnel.
NOTE
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.
