EK1240LT/X and EK1240CLT/X Crimping Tools
Operation
(cont’d)
Pressure Sensor
This tool is equipped with a pressure sensor that alerts
the user of an incomplete crimp.
• If the tool is manually retracted before completion of a
crimp, the red LED and an audible beep will be active
for 2 seconds.
• If the tool is unable to reach the required crimp force,
the red LED, work light, and an audible beep will pulse
until after the trigger is released.
Procedure
1. Clean the die seat area.
2. Install the proper size and type of crimping dies.
3. Press the release button on the C-head and slide
one of the die halves into the jaw. Release the
button and slide the die half until the retainer snaps
and locks the die into place.
4. Press the release button on the ram body (located
in the cutout) and slide the other die half in. Release
the button and slide the die half until the retainer
snaps and locks the die into place.
5. Follow the connector manufacturer’s instructions for
appropriate cable strip length and surface preparation.
6. Insert cable fully into connector and center the con-
nector between the dies.

7. Using the sequence illustrated here, press the
trigger to advance the dies. Continue to crimp until
the pressure relief valve activates.
Note: Pressure relief occurs at approximately
106 kN (12 tons) and is indicated by an audible “pop.”
8. After achieving pressure relief, the ram automatically
returns to the start position and the dies retract.
9. To stop the ram from returning fully, activate the
trigger for a brief moment. This activation will close
the retraction valve and stop the retraction motion.
10. When using KC12-type dies, complete the number
of crimps listed on the “Connector Selection” chart
in this manual. For other dies, complete the number
of crimps specified by the manufacturer.
11. Remove the connector from the crimping tool.
Note: After completing the last crimp on an aluminum
connector, wipe off the excess oxide inhibitor.
An incomplete crimp can cause a fire.
• Use proper die, connector, and cable combinations.
Improper combinations can result in an incomplete
crimp.
• The relief valve sounds and the ram automatically
retracts to indicate a completed crimp. If you do not
hear the sound of the relieve valve or the ram does
not automatically retract, the crimp is not complete.
Failure to observe these warnings could result in
severe injury or death.
