OPERATION
CAUTION: Install only Molex terminals listed above with this tool. Do not crimp hardened objects as damage can
occur to the tool or die.
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. See Figure 1.

Crimping Terminals
1. Select 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. See
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. See Figure 3.

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.

Note:
Figure 6
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.

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 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. See 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.

Right or Left Hand Operation
MATCH
UP MARKS
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:
Figure 9
BACK
FRONT
1. The locator must be removed before reversing the
tooling.
2. Remove the M3 BHCS which is holding the upper tooling.
3. 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.
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
LUBRICATION POINTS
replacement section.
(BOTH SIDES) LIGHT OIL
(EVERY 3 MONTHS OR
5,000 CRIMPS)
Maintenance
It is recommended that each operator of the tool be made aware of, and
responsible for, the following maintenance steps:
Figure 10
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.
RATCHET RELEASE
LEVER
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
Figure 11
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
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.

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. 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.
