How to use

Select the appropriate terminal or ferrule for the cable and strip the conductor to the recommended length. Insert the conductor into the terminal or ferrule, then place the terminal into the crimper’s jaw aligned with the correct crimping zone. Squeeze the handles evenly and firmly until the crimp is completed and the terminal is held securely. Inspect the crimp for uniform compression and mechanical stability before use. For different terminal sizes, position the component in the corresponding crimping area of the jaw.

Usage recommendations

Use the Dedra crimper with connectors and ferrules that match the cable cross-section. Regularly inspect the tool for wear and keep the jaws clean of debris to maintain consistent crimps. For high-current or mission-critical connections, verify crimp quality with a pull test or electrical continuity check and replace the tool if deformation or excessive wear appears.
