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.

Crimping Terminals
Open the tool by first closing the jaws sufficiently for the ratchet mechanism
to release.
JAWS SLIGHTLY CLOSED
1. Hold hand tool with the locator facing up. Insert the closed end
connector in the correct slot (8). Make sure that the shoulder of the
PRE-TWISTED
connector is resting on the locator plate (See Figure 1).
WIRE
2. Close the hand tool jaws until the connector is held snug in place. Load
CONNECTOR
the connector with the desired wire combination (See Figure 2 and 3).
Figure 2
Complete the crimp by closing the hand tool handles until they release.
Note:
The tamper proof ratchet action will not release the tool until it has been fully closed.

3. 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.
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.

RHT2080 Hand Crimp Tool
Maintenance
It is recommended that each operator of the tool be made aware of,
and responsible for, the following maintenance steps:
LUBRICATION POINTS
(BOTH SIDES)
LIGHT OIL (EVERY 3 MONTHS
OR 5,000 CRIMPS)
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 64001-2500 (RHT-2080) was engineered for
durability, but like any fine piece of equipment it needs cleaning
and lubrication for a maximum service life of trouble-free
Figure 4
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)
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
PRELOAD
crimping force of the hand tool to obtain proper
1.00
TEST POINT
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
(CCW) 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
handle preload 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.

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:
Repetitive use of this tool should be avoided.
