Testing
Mechanical
The tensile test or pull test is a means of evaluating the mechanical properties of the crimped connections. The
following chart shows 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 Female Quick Disconnects Terminals
1. There are 3 tab locator blades supplied with the tool. One is for
.187 and .250 tabs; another is for .205 tabs and .110 Tabs and
another for LIF terminals. Make sure the proper blade is installed
on the top of the locator and the others are stored on the bottom of
the locator. For proper orientation of the locator blade see Figure 1.
2. Push the terminal onto the tab locator all the way to the stop in the
proper color-coded nest. The barrel of the terminal should be up
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. The wires end should butt against
the wire stop stamped into each terminal. Cycle the tool.
Crimping Piggyback Quick Disconnect Terminals
Follow the procedure described above but the terminal
must be loaded with the male tab up and the barrel down.

Note: The tamper proof ratchet action will not release the tool until it has been fully closed.
1. 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.
Crimping Bullet Terminals
1. Adjust the locator up or down until the bullet terminal being crimped sits flat and straight into the tool.
2. Push up on the locator blade and insert the terminal in the proper nest with the barrel up and against the
locator blade. Release the locator blade to hold the terminal in position. See Figure 4. Locator may be
raised or lowered so terminal sits flat and straight in the tool.
3. Partially close the tool to hold the terminal in place.
4. Insert the properly stripped wire into the terminal barrel. See Figure 5. The wires end should stop against
the locator blade. Cycle the tool.
Note: The tamper proof ratchet action will not release the tool until it has been fully closed.
5. Push the locator blade to remove the crimp and inspect for proper crimp location. Locator is adjustable up
and down to keep terminals straight after crimping. See Figure 4. 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
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 6, 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 7.
How to Adjust Tool Preload (See Figure 7)
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, a soft metal slug
or solder should be crimped in the conductor nest and the “X” Dimension measured 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 7) to recalibrate.
