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 indicates the minimum acceptable
force to break or separate the terminal from the conductor.

OPERATION
Open the tool by first closing the jaws sufficiently for the ratchet mechanism to release.
Crimping Terminals
1. There are 2 tab locator blades supplied with the tool. One is for .187 and .250
tabs; the other is for .205 tabs and .110 Tabs. Make sure the proper blade is
installed on the top of the locator and the other is stored on the bottom of the
locator.
2. Push the terminal onto the tab locator all the way to the stop in the color-coded
nest. The barrel of the terminal should be up. See Figure 1.
3. Partially close the tool to hold the terminal in place. (See Figure 2.
4. Insert the properly stripped wire into the terminal barrel. See Figure 2 and 3. Cycle the tool.
Note: The tamper proof ratchet action will not release the tool until it has been fully closed.
5. Remove the crimp and inspect for proper crimp location. Molex offers a Crimp Inspection Handbook for closed barrel industrial
product. See our website or contact your sales engineer.
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. This
hand tool 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 4, 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 5.
How to Adjust Tool Preload (See Figure 5)
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 prior to 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.

Caution: Repetitive use of this tool should be avoided.
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.
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.
