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.

Revision: D Revision Date: 02-09-15

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.
