EK1550LT and EK1550LX Battery-powered 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.
For a cUL or UL classified crimp, see the connector
table in this instruction manual.
Preparation
Note: 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.
1. Select a proper size and type of connector to
correspond with the wire or cable.
2. Strip the cable to an appropriate length. Follow the
connector manufacturer’s instructions.
Note: Apply an oxide inhibitor, if required.
See the connector manufacturer’s instructions.
3. Clean the die seat area.
Crimping
1. Insert the cable fully into the connector.
2. Align the connector between the crimping dies as
shown below.
3. For a UL or cUL classified crimp, complete the
number of crimps specified under “Connector
Selection”.
4. For a single crimp, position the connector so the
crimp will be located at the center of the barrel.

5. Depress the trigger to advance the piston. Hold the
trigger down until the piston automatically begins to
retract.
Notes: If the crimping tool does not automatically
retract, the crimp is incomplete.
It is normal for the battery load display to light at
both the beginning and near the end of the crimping
cycle.
6. Release the trigger until the piston retracts
completely.
7. 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.
Note: if it is necessary to retract the piston before
a crimp cycle is complete, push the retract button.
Pushing the retract button will result in complete
retraction of the piston.
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.
