Testing
Mechanical
The tensile test, or pull test, is a means of evaluating the mechanical properties of the crimped connections. The following charts
show the UL specifications for various wire sizes. The tensile strength is shown in pounds, and it indicates the minimum acceptable
force to break or separate the terminal from the conductor.

OPERATION
Crimping Terminals
Open the tool by first closing the jaws sufficiently for the ratchet mechanism to release.
1. Adjust the locator up or down until the terminal being run sits flat and straight in
the tool.
2. Position the locator for the proper color-coded nest by removing the #4-40 X
3/8”Lg. BHSCS under the bracket of the locator. Place it in the desired position that
corresponds with the color-coded nest being used. Tighten the BHSCS.
3. Place the terminal into the locator and push until the terminal is flush against the
locator face shown in Figure 1.
4. Partially close the hand tool jaws until the connector is held snug in place, See Figure 2.
5. Insert the properly stripped wire into the terminal barrel (See Figure 2 and 3).
6. Complete the crimp by closing the hand tool handles until they release.
Note: The tamper proof ratchet action will not release the tool until it has been fully closed.

7. Remove the crimp and inspect for proper crimp. Molex offers a Crimp Inspection Handbook for closed barrel industrial product.
See our website or contact your sales engineer.
Crimping Butt Splices
When crimping butt splices, the locator must be removed.
1. Position the splice into the proper color-coded nest.
2. Partially close the tool to hold the splice in place.
3. Insert the properly stripped wire into the splice. The wires end
should butt against the tab in the terminal (See Figure 4). Cycle the
tool.
4. Remove the crimped splice. Inspect for proper crimp location.
5. Rotate the butt splice terminal 180°, so that the opposite end of
splice is in the nest.
6. Repeat steps 2 thru 4.
Note: Whenever crimping without the locator, make sure the seam of the terminal is oriented up or down in the tool if using
unbrazed product, as this will provide higher pull force values.
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 64001-4500 (RHT-5771) was
engineered for durability, but like any fine piece of
equipment, it needs cleaning and lubrication for a maximum
service life of trouble-free crimping. A light oil, such as 30
weight automotive oil used at the oil points shown in Figure 5, every 5,000 crimps or 3 months will significantly enhance the tool
life and ensure a stable calibration.
4. 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
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 the ratchet release lever, (See Figure 6).

How to Adjust Tool Preload (See Figure 6)
Over the life of the tool, it may be necessary 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. Remove the screw and plastic cover washer. Note the
setting wheel position.
2. Lift the setting wheel off the axle. Turn the eccentric
axle with a screwdriver.
3. Turning the eccentric axle counter-clockwise will increase
handle force.
4. Replace the setting wheel to the axle, aligning the
nearest notch in the setting wheel to the dowel pin.
5. Replace the plastic cover washer and screw.
6. Check the crimp specifications after tool crimp force is adjusted.
Tool Calibration
A Certificate of Calibration (see last page) was supplied with the tool. To
recalibrate this tool, pin gauge measurements should be taken in each
conductor nest and compared to this chart. The tool should be lubricated
before recalibration to ensure consistent measurements. Handle preload is
factory set to 25-45 LBS. See How to Adjust Tool Preload (See Figure 5) to
recalibrate.

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: Repetitive use of this tool should be avoided.
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, applicators and tooling.
