Tool Qualification Notes
1. (Ref) means that the dimension provided is approximate because of the wide range of wires,
conductor stranding, insulation diameter and insulation hardness.
2. An occasional conductor crimp height measurement should be performed. It must lie between
the minimum and maximum crimp height specification.
3. Pull force should be measured with no influence from the insulation crimp. To ensure this, strip
the wire long enough so the terminal insulation grips do not contact the wire insulation.
Notes
1. This tool should only be used for the terminals and wire gauges specified on this sheet.
2. Variations in tools, terminals, wire stranding and insulation types may affect crimp height.
3. This tool is intended for metric conductor sizes. It may not give good insulation crimp support
for insulation sizes outside of the specified range.
4. Molex does not repair hand tools. See warranty on page 5. The replacement parts listed are the
only parts available for repair. If the handles or crimp tooling become damaged or worn, a new
tool must be purchased.
5. Conductor crimp height should be used as the final criterion for an acceptable crimp. Refer to
Molex Quality Crimping Handbook 63800-0029 for additional information on crimping and crimp
testing.
6. Molex does not certify crimp hand tools.

TERMINAL
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. With the hand tool in the open position, pivot the
terminal locator open by pulling up on the locator
knob, and lift the wire stop blade. See Figure 1.
2. Insert the terminal into the profile until the terminal is
fully seated and stops. Make sure the wire stop blade
is fully seated on the terminal behind the conductor
grip section.
3. Gently pivot the locator closed.
4. Bring down the wire stop blade.
5. Slide the pre-stripped wire into the terminal, making sure to aim the wire brush toward
the tip point on the wire stop blade. See Figure 2. Align the wire so that it is parallel and
sitting into the terminal. Maintain a light and constant pressure on the wire that is
seated in the terminal at all times. (Do not let go of the wire.) Be sure to hold the wire
and terminal in place until the terminal is fully crimped. See Figure 3.
6. Close the tool until the ratchet releases.
7. Lift the wire stop blade.
8. Carefully remove the crimped terminal.
Note: The tamper-proof ratchet action will not release the tool until it has been fully closed.
Note: To maintain good brush control and a consistent bell mouth, the crimping instructions must
be followed.

TERMINAL LOCATOR REPLACEMENT
This section describes the procedure for changing locators:
Removal
1. With the tool in the open position, pivot the terminal locator outward.
2. Remove the M4 BHCS. See Figure 4.
Installation
1. Place the locator on the hand tool. Install the M4 BHCS. See Figure 4.
2. Tighten the screw just enough to hold the locator. Make sure the locator can still float freely
with hand pressure.
3. Fully insert the proper terminal into the correct profile slot until the terminal is completely
seated and stops. Then, gently pivot the locator closed.
4. With hand pressure, slowly slide the locator to the correct position. See Figure 5.
5. Gently pivot the locator open without disturbing the location.
6. Hold the locator firmly in place, and slowly tighten the M4 BHCS.
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.
4. Wipe excess oil from the hand tool, particularly from the 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 lifting the ratchet release lever. See Figure 9.

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, Molex 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: Repetitive use of this tool should be avoided.
CAUTIONS
1. Manually powered hand tools are intended for low-volume use 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: Molex crimp specifications are valid only when used with Molex terminals and
tooling.
