4. Operating Instructions

4.1 Pre-Operation Check

• Verify that the correct dies are installed for the cable lug size.
• Ensure the battery is fully charged and securely installed. Check the digital display for battery level.
• Inspect the crimping head for any obstructions or damage.

4.2 Crimping Procedure

1. Prepare the cable by stripping the insulation to the appropriate length for the lug.
2. Insert the stripped cable into the cable lug.
3. Position the cable lug and cable between the installed dies in the crimping head. Ensure the lug is centered and stable.
4. Press and hold the Start button (trigger) to initiate the crimping process. The hydraulic mechanism will advance, closing the dies and crimping the lug.
5. The tool features automatic pressure relief; it will stop when the crimp is complete and the dies will retract automatically.
6. If the dies do not retract automatically, press the Resume Button to manually restore the piston.
7. Remove the crimped cable and lug from the tool.
