IDT-12-N Hydraulic Crimping Tool
Operation
(cont’d)
Preparation
1. Select a proper size and type of connector to corre-
spond with the wire or cable.
2. Strip the cable to an appropriate length. Follow the
instructions in the Ilsco stuffer sheet.
Note: Apply an oxide inhibitor, if required. Refer to
the Ilsco stuffer sheet.
Crimping
1. Insert the cable fully into the connector.
2. Position the connector in the crimping head.
Note: Position the lug connectors so the tang is
perpendicular to the direction of ram travel, as
shown.

3. If open, close the die head and push in the
movable pin unit. Make sure the movable pin is fully

5. Pump the handle to advance the ram. Continue to
pump until the pressure relief valve activates.
Note: Pressure relief is indicated by an audible
“pop” and a sudden drop in handle force.
6. To release the hydraulic pressure, pull the release
trigger back while pressing down on the handle.
Note: To prevent the ram from retracting
completely, release the trigger. This speeds the
crimping process when a single connector requires
several crimps.
7. Complete the number of crimps specified in the
Ilsco stuffer sheet.
8. To remove the tool from a splice, pull the movable
pin on the die head and open the crimping head.
