  • Select the appropriate die set for the connectors (crimp lugs or splices) for use with the presshead
  • Open the latch and release the upper die holder of the hydraulic crimping tool or presshead
  • Insert one die into the upper die holder and one die into the lower die holder
  • Close the latch on the presshead tool
  • Insert the conductor into the connector (crimp lug or splice)
  • Locate the connector between the crimping dies at the desired crimp position
  • Operate the pump to advance the main ram
  • Continue to operate the pump, the ram will gradually advance until crimp dies meet
  • Recommended to keep pumping until the maximum pressure valve is activated and a “click” is heard
  • After crimping completion press the release lever to release oil pressure of the Cembre RHU230-630
  • Recommend only Cembre Lugs & Connectors are used with Cembre tooling

Cembre RHU230-630 should be transported in VAL 230-630 steel case.
