▲Insulation Crimp Note:
Due to the terminal’s insulation grip design and/or
insulation diameter range, this tool uses “overlap”
form geometry in the insulation punch. This
produces an overlap insulation crimp (A620 –
compliant). While the insulation punch profile may
appear “lopsided”, this is a normal condition for this
tool. ee figure to the right.

occur to the tool or die.


 Tool Qualification Notes:
1. Pull Force should be measured with no
influence from the insulation crimp.
2. The above specifications are guidelines to an
optimum crimp.
Note:
A crimp height chart is provided with this manual
as Reference Only. Due to the wide range of
wires, strands, insulation diameters, and
durometer available, actual crimp height
measurements may very slightly. An occasional,
destructive, pull force test should be performed to
check hand tool crimp. Pull Force value must
exceed the minimum pull force specification.
OPERATION
Open the tool by squeezing the handles together. At the end of the closing stroke, the ratchet mechanism will
release the handles and the hand tool will spring open. ee Figure 1.

1. elect the desired terminal listed in the preceding charts.
2. Make sure the center of the locator is in the down position. With the locator attached, push the locator button
on the back of the hand tool to bring the locator forward through the tooling. ee Figure 2.
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. ee Figure 3.
4. Release the locator button, allowing the locator to return to the crimping position.
5. Close the tool handle until the first ratchet position engages. ee Figure 4.
6. Insert the properly stripped wire through the terminal and against the wire
stop. ee Figure 5.
7. Crimp the terminal by squeezing the tool handles until the ratchet
mechanism cycle has been completed. Release the handles to open the
jaws.
Note: The tamper proof ratchet action will not release the tool until it has been fully closed.
8. Remove the crimped terminal from the terminal locator by
pulling on the wire.
9. Visually inspect the crimped terminal for proper crimp location.
10. On some large O.D. wires, it may not be possible to insert the
wire with the tool partially closed. Those wires should be
inserted with the hand tool in the open position. Insert the wire
above the terminal in the punch and against the wire stop then
close the tool. ee Figure 6.

Locator Replacement
ee the parts list on the last page of this
document for the proper locator order number.
Follow the steps below to replace the locator.
1. Open the crimp hand tool.
2. queeze gently on the lower area shown in
Figure 7A with your thumb and index finger.
The lower tabs of the locator should
disengage from the hand tool.
3. Lift and pull away from the hand tool. The
top locator hooks should slip out of the top
slots easily. ee Figure 7A.
4. To reinstall the new locator, make sure the
hand tool is in the open position.
5. Press the red insert down as far as it will go
as shown in Figure 7B.
6. Holding onto the lower part of the locator with your
thumb and index finger, insert the locators top
hooks (2) into the hand tool top slots.
7. Rotate the locator down and press the lower tabs
into the two bottom slots of the hand tool. To
secure the locator into place, the lower tabs must
snap into place on the hand tool frame.
Ri ht or Left Hand Operation
This hand tool has an added feature that can be
converted from a right handed application to a left
handed application. It is necessary to reverse the
tooling if using the left handed application along with
the locator. Follow the steps below:
1. The locator must be removed before reversing the tooling.
2. Remove the M3 BHC which is holding the upper tooling.
3. Flip the upper tooling to the opposite side and replace the M3 BHC . Make sure the small markings on the
front and back of the hand tool frame, match up and are on the outside of the hand tool frame. ee Figure 8
and 9.
4. Do the same thing with the lower tooling and tighten
the M3 screws. Be sure the small markings line up.
5. Reinstall the locator by following the Instructions in
the locator replacement section.

Maintenance
It is recommended that each operator of the tool be made aware of, and
responsible for, the following maintenance steps:
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 durability but like any other equipment it needs
cleaning and lubrication for a maximum service life of trouble free
crimping. Light oil (such as 30 weight automotive oil) used at the oil
points, every 5,000 crimps or 3 months, will significantly enhance the tool
life.
4. Wipe excess oil from hand tool, particularly from crimping 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 prevent objects from becoming lodged in the crimping dies,
and store the tool in a clean, dry area.
Miscrimps or Jams
hould 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 release lever in the movable handle. ee Figure 11.
How to Adjust Tool Preload (See Fi ure 12)
This hand tool is factory preset to 25-45 LB . preload. It may be necessary
over the life of the tool to adjust tool handle preload force. Listed below are the
steps required to adjust the crimping force
of the hand tool to obtain proper crimp
conditions:
1. Hold the hand tool in the palm of your
hand as shown in Figure 10. Using
the index finger squeeze the link
towards the top of the hand tool
frame. This will release the preload
adjustment wheel.
2. Rotate the setting wheel counter-
clockwise (CCW) to increase handle
force. The numbers will display
higher. To decrease handle force
rotate the setting wheel clockwise
(CW).
3. Release the link to lock the setting
wheel in place.
4. Check the crimp specifications or conduct a pull test after tool handle preload force is adjusted.

Warranty
This tool is for electrical terminal crimping purposes only. This tool is made of the best quality materials. All vital
components are long life tested. All tools are warranted to be free of manufacturing defects for a period of 30
days. hould such a defect occur, we will repair or exchange the tool free of charge. This repair or exchange will
not be applicable to altered, misused, or damaged tools. This tool is designed for hand use only. Any clamping,
fixturing, or use of handle extensions voids this warranty.
CAUTION: Molex crimp specifications are valid only when used with Molex terminals and tooling.
CAUTIONS:
1. Manually powered hand tools are intended for low volume or field repair. This tool is NOT intended for
production use. Repetitive use of this tool should be avoided.
2. Insulated rubber handles are not protection against electrical shock.
3. Wear eye protection at all times.
4. Use only the Molex terminals specified for crimping with this tool.
Certification
Molex does not certify or re-certify hand tools but rather supplies the following guidelines for customers to re-certify
hand tools.
% This tool is qualified to pull force only. To re-certify, crimp a terminal to a wire, which has been stripped
12.7mm (1/2”) long, so there is no crimping of the insulation. Pull the terminal and wire at a rate no faster than
25mm (1.00”) per minute. ee the Molex web site for the Quality Crimp Handbook for more information on pull
testing.
% If the tool does not meet minimum pull force values, handle preload should be increased and the pull test
rerun, ( ee How to Adjust Preload).
% When the hand tool is no longer capable of achieving minimum pull force, it should be taken out of service and
replaced.
