Hand Crimp Tool For Micro-Fit 3.0™ Crimp Terminals
The above terminal drawing is a generic terminal
representation. It is not an image of a terminal listed
in the scope.
▲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).

After crimping, the conductor profiles should measure the following. See Notes below.

Note:
A crimp height chart is provided with this
document 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

Locator Replacement
LOCATOR
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.

Right or Left Hand Operation
This hand tool has an added feature that can be

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 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.
LUBRICATION POINTS
(BOTH SIDES) LIGHT OIL
(EVERY 3 MONTHS OR
5,000 CRIMPS)
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
Figure 10
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.

RATCHET RELEASE
LEVER
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 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 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.

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 recertify 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.
CAUTION:
Molex tooling crimp specifications are valid only when used with Molex terminals and tooling
manufactured by Molex and sold by Molex or authorized distributors ("Molex Tooling"). When
using tooling other than Molex Tooling with Molex specific connector systems listed in our ATS
documents, the Molex tooling qualification does not apply and the responsibility for full
CAUTION qualification of the connector system is that of the customer.
Molex accepts no liability for connector performance or tooling support where tooling other
than Molex Tooling is used or where Molex Tooling is modified.
