▲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. See figure to the right. (Some tools with
multiple crimp pockets may not have the “overlap”
profile on all pockets).
CRIMP SPECIFICATIONS
After crimping, the crimp profiles should measure the following:

CAUTION: Install only Molex terminals listed above with this tool. Do not crimp hardened objects as damage can
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 durometers 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 specifications listed.
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.

1. Select the desired terminal listed in the preceding charts.
2. Make sure the locator is attached behind the lower tooling and is above all the
anvils surfaces.
3. The spring loaded wire stop should be clear of the locator’s cavity, if not push up
on the red tab to move the wire stop out of the way while inserting the terminal.
See Figure 3.
4. Load the terminal into the proper nest opening in the locator based on the wire
gauge or terminal type markings on the hand tooling. See Figure 3.
. Partially close the tool handle until the first ratchet position engages, and
holds the terminal in place. See Figure 4.
6. Insert the properly stripped wire through the terminal and against the wire
stop. See Figure .
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. See Figure 6.
Locator Replacement
See 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. Squeeze gently on the lower area shown in Figure 7 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. See Figure 7.
4. To reinstall the new locator, make sure the hand tool is in the open
position.
. 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.
6. 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 BHCS which is holding the upper tooling.Flip the upper tooling to the opposite side and
replace the M3 BHCS. 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. See Figure 8 and 9.
3. Do the same thing with the lower tooling and tighten the M3 screws. Be sure the small markings line up.
4. 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 ,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.
. 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
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 release lever in the movable handle. See Figure 11.

How to Adjust Tool Preload
(See Fi ure 12)
This hand tool is factory preset to 2 -4
LBS. 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 12. 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. Should 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
2 mm (1.00”) per minute. See 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, (See 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.
