OPERATION
CAUTION: Crimp only the Molex terminals listed in the scope for this tool. Do not crimp
hardened objects because damage can occur to the tool frame or crimp dies.
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 tool.
See 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.
See Figure 4.
6. Insert the properly stripped wire through the terminal and
against the locator. See 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, and then close
the tool. See Figure 6.
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.

Locator Replacement
Follow the steps below to remove and install the locator:
1. Open the hand crimp 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 center of the locator 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 locator’s top hooks
into the hand tool’s 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-Handed Operation
This hand tool has an added feature in that it 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.
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 Figures
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 a 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. See Figure 10.
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 the 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 Figure 12)
This hand tool is factory preset to 25-45 pounds. 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 your index
finger, squeeze the link
toward the top of the hand
tool frame. This will release
the preload adjustment
wheel.
2. Rotate the setting wheel
counterclockwise (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.

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 website 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.
