SCOPE

VibraKrimpFemale Non-Insulated Quick Disconnects, 24-26 AWG

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 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, and check for insulation closure. Molex offers a Crimp Inspection

Handbook for closed barrel industrial product. See our website or contact your sales engineer.

6. If the insulation part of the crimp needs to be adjusted, first loosen the M4 screw on the bottom tool jaw, then insert a 3/32 hex

wrench (supplied) into the bottom of the lower die. See Figure 4. A clockwise (CW) rotation decreases insulation crimp while a

counter-clockwise (CCW) rotation increases insulation crimp. After adjusting retighten the M4 screw.

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 pin, pivot points and bearing surfaces

are protected with a thin coat of high quality machine

oil. Do not oil excessively. The 64003-7100 (RHT-4753) 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.
