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.

. 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 .

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.

. 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.

Rig t 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

the M3 screws. Be sure the small markings line up.

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 12. 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. 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.
