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 may be available.

1. INTRODUCTION
Straight Action Hand Tool CAT-HT-179-2030-13 (Figure 1)
was designed to crimp CC79 Series contacts for the MMSD
and MMSS Mini Mate series.
The wire crimper bottoms against the anvil before the ratchet
releases. This is a design feature that assures maximum
electrical and tensile performance of the crimp. Do NOT re-
adjust the ratchet.
Dimensions in these instructions are in metric units [with
inches in brackets]. Figures are for reference only and are
not drawn to scale.
For conversions to left handed tools, recalibrations, or
locator replacements please contact Samtec Applica-
tion Tooling Group.
2. DESCRIPTION
The front of the tool is marked with the tool part number.
The tool features a fixed die (crimper), a movable die
(anvil), a locator, and a ratchet. The locator positions the
contact and limits the insertion distance of the stripped wire
into the contact. The ratchet assures full crimping of the
contact. Once engaged, the ratchet will not release until the
dies have been fully closed.
3. CRIMPING PROCEDURE
Do NOT cut or nick the wire strands during wire stripping.
1. Select the desired terminal listed in the Figure 3.
2. Make sure the center of the locator is in the down posi-
tion. With the locator attached, push the locator button
on the back of the hand tool to bring the locator forward
through the tooling.
3. While holding the locator button in, load the terminal into
the proper nest opening in the locator based on the wire
gauge or terminal type markings on the hand tooling.
4. Release the locator button, allowing the locator to return
to the crimping position.
5. Close the tool handle until the first ratchet position en-
gages.
6. Insert the properly stripped wire through the terminal and
against the wire stop. See Figure 2.

7. Crimp the terminal by squeezing the tool handles until
the ratchet mechanism cycle has been completed. Release
the handles to open the jaws.
8. Remove the crimped terminal from the terminal
locator by pulling on the wire.
9. Visually inspect the crimped terminal for proper
crimp location.
Damaged contacts should not be used. If a damaged contact
is evident, it should be cut from the wire and replaced with a
new one.
4. MAINTENANCE AND INSPECTION PROCEDURE
It is recommended that a maintenance and inspection pro-
gram be performed periodically to ensure dependable and
uniform terminations. Frequency of inspection depends on:
• The care, amount of use, and handling of the hand tool,
• The presence of abnormal amounts of dust and dirt,
• 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.
4.1 DAILY MAINTENANCE
1. Remove dust, moisture, and other contaminants with a
clean brush, or soft, lint free cloth.
2. Do not use any abrasive materials that could damage the
tool.
3. Make certain all pins; pivot points and bearing surfaces
are protected with a thin coat of high quality machine oil.
Do not oil excessively. The tool was engineered for dura-
bility but like any other equipment it needs cleaning and
lubrication for a maximum service life of trouble free crimp-
ing. Light oil (such as 30 weight automotive oil) used at the
oil points, every 1,000 crimps or 3 months, will significantly
enhance the tool life. See Figure 4.
4. Wipe excess oil from hand tool, particularly from crimp-
ing area. Oil transferred from the crimping area onto
certain terminations may affect the electrical characteristics
of an application.
5. When tool is not in use, keep the handles closed to pre-
vent objects from becoming lodged in the crimping dies,
and store the tool in a clean, dry area.

4.2. CRIMP HEIGHT INSPECTION
This inspection requires the use of micrometer with a modi-
fied anvil as shown in Figure 5.
Proceed as follows:
1. Select a contact and wire (maximum size) for each crimp
section.
2. Refer to Section 3 and crimp the contact(s).
3. Using a crimp height comparator, measure wire barrel
crimp as shown in Figure 5. If the crimp height conforms to
applicable specifications, the tool is considered dimension-
ally correct.

4.3 MISCRIMPS OR JAMS
Should this tool ever become stuck or jammed in a partially
closed position, do Not force the handles open or closed.
The tool will open easily by pressing up on the ratchet re-
lease lever in the movable handle. See Figure 6.
