OPERATION

CAUTION: Install only Molex terminals listed above with this tool. Do not crimp hardened objects as damage can

occur to the tool or die.

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. See Figure 1.

Crimping Terminals

1. Select the desired terminal listed in the

preceding charts.

2. Make sure the center of the locator is in the

down position. With the locator attached,

push the locator button on the back of the

hand tool to bring the locator forward through

the tooling. See Figure 2.

3. While holding the locator button in, load the

terminal into the proper nest opening in the

locator based on the wire gauge or terminal type markings on the hand tooling. See Figure 3.

4. Release the locator button, allowing the locator to return to the crimping

position.

5. Close the tool handle until the first ratchet position engages. See

Figure 4.

6. Insert the properly stripped wire through the terminal and against the

wire stop. See Figure 5.

7. Crimp the terminal by squeezing the tool handles until the ratchet

mechanism cycle has been completed. Release the handles to open

the jaws.

Note: The tamper proof ratchet action will not release the tool until it has been fully closed.

8. Remove the crimped terminal from the terminal

locator by pulling on the wire.

9. Visually inspect the crimped terminal for proper

crimp location.

10. On some large O.D. wires, it may not be possible

to insert the wire with the tool partially closed.

Those wires should be inserted with the hand tool

in the open position. Insert the wire above the

terminal in the punch and against the wire stop

then close the tool. See Figure 6.

Note:

A crimp height chart is provided with this manual as Reference Only. Due to the wide range of wires, strands,

insulation diameters, and durometers available, actual crimp height measurements may very slightly. An

occasional, destructive, pull force test should be performed to check hand tool crimp. Pull Force value Must

exceed the Minimum pull force specifications listed.

Locator Replacement

See the parts list on the last page of this

document for the proper locator order number.

Follow the steps below to replace the locator.

1. Open the crimp hand tool.

2. Squeeze gently on the lower area shown in

Figure 7A with your thumb and index finger.

The lower tabs of the locator should

disengage from the hand tool.

3. Lift and pull away from the hand tool. The

top locator hooks should slip out of the top

slots easily. See Figure 7A.

4. To reinstall the new locator, make sure the

hand tool is in the open position.

5. Press the red insert down as far as it will go

as shown in Figure 7B.

6. Holding onto the lower part of the locator with your thumb and index finger, insert the locators top hooks (2)

into the hand tool top slots.

7. Rotate the locator down and press the lower tabs into the two bottom slots of the hand tool. To secure the

locator into place, the lower tabs must snap into

place on the hand tool frame.

Right or Left Hand Operation

This hand tool has an added feature that can be

converted from a right handed application to a left

handed application. It is necessary to reverse the

tooling if using the left handed application along with

the locator. Follow the steps below:

1. The locator must be removed before reversing

the tooling.

2. Remove the M3 BHCS which is holding the upper

tooling.

3. Flip the upper tooling to the opposite side and

replace the M3 BHCS. Make sure the small

markings on the front and back of the hand tool frame, match up and are on the outside of the hand tool frame.

See Figure 8 and 9.

4. Do the same thing with the lower tooling and tighten

5. Reinstall the locator by following the Instructions in

the locator replacement section.

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 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 hand tool, particularly from crimping area. Oil

transferred from the crimping area onto certain terminations may

affect the electrical characteristics of an application.

5. 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 up on the ratchet release lever in the movable handle. See Figure

11.

How to Adjust Tool Preload (See Figure 12)

This hand tool is factory preset to 25-45 LBS. preload. It may be necessary

over the life of the tool 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. Hold the hand tool in the palm of your hand as shown in Figure 10.

Using the index finger squeeze the link towards the top of the hand tool

frame. This will release the preload adjustment wheel.

2. Rotate the setting wheel counter-clockwise (CCW) to increase handle force. The numbers will display higher.

To decrease handle force rotate the setting wheel clockwise (CW).

3. Release the link to lock the setting wheel in place.

4. Check the crimp specifications or

conduct a pull test after tool handle

preload force is adjusted.

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.

CAUTION: Molex crimp specifications are valid only when used with Molex terminals and tooling.

CAUTIONS:

1. Manually powered hand tools are intended for low volume 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.

Certification

Molex does not certify or re-certify hand tools but rather supplies the following guidelines for customers to re-certify

hand tools.

% This tool is qualified to pull force only. To re-certify, crimp a terminal to a wire, which has been stripped

12.7mm (1/2”) long, so there is no crimping of the insulation. Pull the terminal and wire at a rate no faster than

25mm (1.00”) per minute. See the Molex web site for the Quality Crimp Handbook for more information on pull

testing.

% If the tool does not meet minimum pull force values, handle preload should be increased and the pull test

rerun, (See How to Adjust Preload).

% When the hand tool is no longer capable of achieving minimum pull force, it should be taken out of service and

replaced.
