Operation
Electric shock hazard:
This tool is not insulated. When
using this unit on or near energized
electrical lines, use proper personal
protective equipment.
Failure to observe this warning could
result in severe injury or death.
Wear eye protection when operating
this tool.
Failure to wear eye protection could
result in serious eye injury from flying
debris or hydraulic oil.
Skin injection hazard:
• Do not use hands to check for
leaks.
• Depressurize the hydraulic system
before servicing.
Oil under pressure easily punctures
skin causing serious injury, gan-
grene, or death. If you are injured by
escaping oil, seek medical attention
immediately.
An incomplete crimp can cause a fire.
• Use proper connector and cable combinations.
Improper combinations can result in an incomplete
crimp.
• The handle load will drop suddenly to indicate a
completed crimp. If the handle load does not drop
suddenly, the crimp is not complete.
Failure to observe these warnings could result in
severe injury or death.
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
connector between the dies.
7. Using the sequence illustrated here, pump the
handles to advance the dies. Continue to pump 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. 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.
10. Remove the connector from the crimping tool.
11. Press the trigger lock upward to lock the trigger.
Note: After completing the last crimp on an alumi-
num connector, wipe off the excess oxide inhibitor.
