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. 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.
Note: After completing the last crimp on an aluminum
connector, wipe off the excess oxide inhibitor.
Pinch points:
Keep hands away from the crimping
tool head when crimping.
Failure to observe this warning could
result in severe injury or death.
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
or servicing 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 oil
leaks. Oil under pressure easily
punctures skin. If injured, seek
medical attention immediately to
remove oil.
Failure to observe this warning could
result in serious injury, gangrene, or
death.
An incomplete crimp can cause a fire.
• Use proper die, connector, and cable combina-
tions. Improper combinations can result in an
incomplete crimp.
• An audible “pop” indicates that the crimping tool
has achieved a complete crimp. If you do not
hear a “pop,” the crimp is incomplete.
Failure to observe these warnings could result in
severe injury or death.
