3. Setup
3.1 Changing Jaws
The IWISS iCrimp tool features a quick-change mechanism for jaws, requiring no additional tools. Follow these steps:
- Ensure the crimping tool is fully open.
- Locate the small lever or button on the side of the jaw mechanism.
- Press the lever/button and slide the installed jaws straight out.
- Select the desired jaw pair for your application (refer to Section 2.3).
- Align the new jaws with the slots on the tool and slide them in until they click securely into place.

4. Operating Instructions
Follow these steps for proper crimping:
- Select Correct Jaws: Based on the type and size of your terminal and wire, choose the appropriate jaw pair (refer to Section 2.3). Install them as described in Section 3.1.
- Adjust Crimping Force (if necessary): The tool comes with a factory setting. If you find crimps are too loose or too tight, use the adjustable knob to modify the crimping force. Turn clockwise to increase force, counter-clockwise to decrease.
- Prepare Wire: Strip the insulation from the end of the wire to the appropriate length for your terminal. Ensure the wire strands are neat and untwisted.
- Position Terminal: Place the terminal into the selected crimping slot on the jaws. Close the handles slightly until the jaws hold the terminal in place.
- Insert Wire: Insert the stripped wire into the terminal. Ensure all wire strands are fully seated within the terminal's crimp barrel.
- Perform Crimp: Squeeze the tool handles firmly and completely until the ratchet mechanism releases. This ensures a full and proper crimp.
- Inspect Crimp: After crimping, gently tug on the wire to ensure it is securely fastened within the terminal. The crimp should appear uniform and tight.

5. Maintenance
Proper maintenance ensures the longevity and optimal performance of your crimping tool:
- Cleaning: After each use, wipe down the tool and jaws with a clean, dry cloth to remove any debris, dust, or residue.
- Lubrication: Periodically apply a light machine oil or Moly grease to the pivot points and moving parts of the tool to maintain smooth operation. Avoid over-lubricating.
- Storage: Store the crimping tool and all jaw sets in the provided durable storage case in a dry, clean environment to prevent corrosion and damage.
- Inspection: Regularly inspect the jaws for wear, damage, or deformation. Replace any damaged jaws to ensure consistent crimp quality.
6. Troubleshooting
If you encounter issues with your crimping tool, consider the following:
- Poor Crimp Quality (Loose/Deformed):
- Ensure the correct jaw type is selected for the terminal and wire size.
- Check if the wire is stripped to the correct length and fully inserted into the terminal.
- Adjust the crimping force knob (clockwise to increase force).
- Inspect jaws for wear or damage.
- Tool Jams/Sticks:
- Ensure the ratchet mechanism is clean and lubricated.
- Use the quick release lever if the tool becomes stuck during an operation.
- Jaws Not Changing Easily:
- Ensure the tool is fully open.
- Check for any debris obstructing the jaw slots.
