Æ Wires should be placed vertically for double crimp.
Í To Achieve IPC-A-620 Class 2 Crimps, the following over-all wire insulation diameter ranges are recommended:
1. Profile A: 3.35-4.57mm (.132-.180 inch)
2. Profile B: 3.35-4.57mm (.132-.180 inch)
3. Profile C: 3.05-4.57mm (.120-.180 inch)
Pull Force should be measured with no influence from the insulation crimp.
The above specifications are guidelines to an optimum crimp.
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.
Crimping Terminals
1. Select the desired terminal listed in the preceding charts.
2. Swing the terminal locator away from the crimp tool shown in Figure 1. Some terminals with large insulation grips may interfere
with the crimp tooling when swinging the locator into position. The terminal must then be loaded into the locator in the
closed/crimp position. See Figure 2.

3. Press down on the wire stop on the locator as shown in Figure1. Insert the proper terminal into the proper nest opening. Make
sure when choosing the nest opening, it will correspond with the A, B or c profile on the hand tool.
4. Return the locator to its original position.
5. Insert the proper wire over the terminal. Gently touch the wire stop with the end of the wire. See Figure 3 and 4.
6. Compress the terminal by squeezing the tool handles until the ratchet mechanism cycle has been completed. Release handles to
open the jaws.
Note: The tamper proof ratchet action will not release the tool until it has been fully closed.
7. Remove the crimped terminal from the terminal locator by pressing down on the wire stop and gently pulling on the wire. The
terminal locator can be in either position.
8. Visually inspect the crimped terminal for proper crimp
location.
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, actual crimp height measurements
may very slightly. An occasional, destructive, pull force test
should be preformed to check hand tool crimp. Pull Force value
must exceed the minimum pull force specifications listed.

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. Swing the existing locator open and away from the hand tool.
3. Firmly press down on the brass pivot shaft with your thumb, while pulling the
locator up. Slip the locator off the top of the brass pivot shaft. See Figure 5.
4. Replace it with the proper locator by putting over the brass pivot shaft and
snapping it into place.
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 equipment it needs cleaning and lubrication for a maximum
service life of trouble free crimping. Use light oil (30 weight automotive oil), at all the oil points, every 5,000 crimps or 3
months. This will significantly enhance the tool life. See Figure 6.
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 (See Figure 7)
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 rotating the small slotted screw marked with an arrow. See
Figure 7.
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.

Revision: A Revision Date: 02-12-07
Hand held crimping tools are intended for low volume, prototyping, or repair requirements only.
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.
CAUTION: Repetitive use of this tool should be avoided.
Certification
Molex does not certify or re-certify commercial grade 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. See the
Molex web site for the Quality Crimp Handbook for more information on pull testing.
% When the hand tool is no longer capable of achieving minimum pull force, it should be taken out of service and replaced.
% This tool is very difficult to disassemble and reassemble. Customer repair is not recommended.
