The crimp on this terminal is not an electrical crimp; the final soldering operation is the electrical
connection. This minimum force is what should be expected when pulling the terminal with both insulation
and conductor crimped.
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.
Before attempting to crimp any
terminals, make sure all the inserts are
correctly placed into the upper and
lower jaws of the hand tool. See Figure
2.
The terminals should be cut from the
reel as shown. See Figure 3. The
carrier strip may be used to assist in
crimping and can be removed after the
crimp is complete.

Crimping Terminals
1. While holding onto the terminal strip with the properly stripped wire, insert it into the lower jaw of the hand tool
until the front of the terminal is flush with the conductor anvil insert. See Figures 4 and 5.
2. Partially close the hand tool jaws until the terminal is held snug in place.
3. Complete the crimp by closing the hand tool handles until they release.
4. Remove the crimp and inspect for proper crimp. Molex offers a Crimp Inspection Handbook for closed barrel
industrial products. See the Molex website or contact your sales engineer.
Note: The tamper-proof ratchet action will not release the tool until it has been fully closed.
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 7.
How to Adjust Tool Crimp Force (See Figure 6)
It may be necessary over the life of the tool to adjust tool-crimping force. Listed below are the steps required to
adjust the crimping force of the hand tool to obtain proper crimp conditions:
1. Loosen the stud nut on the back of the handle.
2. With a screwdriver in the slot on the other side of the stud, adjust the force. Rotating clockwise will increase
the force and rotating counterclockwise will decrease the force.
3. Retighten the nut.
4. Check the crimp specifications after tool force adjustment.
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.
Notes:
1. This tool should only be used for the terminals and wire gauges specified on this sheet.
2. This tool is not adjustable for crimp height; however, crimp force is adjustable (See instructions above).
Variations in tools, terminals, wire stranding and insulation types may affect crimp height.
3. This tool is intended for standard conductor sizes. It may not give a good insulation crimp support for all
insulation sizes.
4. Molex does not repair hand tools (see warranty above). The replacement parts listed are the only parts
available for repair. If the handles or crimp tooling are damaged or worn, a new tool must be purchased.
5. Molex does not certify crimp hand tools.
CAUTION: Molex crimp specifications are valid only when used with Molex terminals and tooling.
