5. Setup

The IWISS SN-01BM Ratchet Crimper is ready for use out of the box. No assembly is required. Before first use, inspect the tool for any shipping damage and ensure the jaws operate smoothly.

5.1 Adjusting Crimping Force

The crimper features an adjustable crimping force mechanism. If crimps are too loose or too tight, locate the adjustment dial near the pivot point of the handles. Rotate the dial to increase or decrease the crimping force as needed for optimal results with different wire gauges and terminal types. Test on a scrap wire and terminal before final application.

6. Operating Instructions

Follow these steps for proper crimping:

1. Prepare the Wire: Strip the insulation from the end of the wire to the appropriate length for your terminal. Ensure the stripped wire is clean and free of frayed strands.
2. Select the Correct Die: Identify the correct crimping slot on the jaws that matches the size of your terminal and wire gauge (AWG 28-20 or 0.08-0.5mm²).
3. Insert Terminal: Place the terminal into the selected crimping slot. Ensure the terminal is seated correctly and held firmly by the crimper jaws.
4. Insert Wire: Insert the stripped wire into the terminal. Make sure the wire conductor is fully within the terminal's crimp barrel and the insulation is positioned correctly for the insulation crimp.
5. Crimp: Squeeze the handles of the crimper firmly until the ratchet mechanism releases automatically. This ensures a complete and secure crimp.
6. Inspect Crimp: Remove the crimped terminal and inspect it for proper formation. The wire conductor should be securely crimped, and the insulation should be held firmly without being cut.

7. Maintenance

• Cleaning: After each use, wipe the crimper jaws and body with a clean, dry cloth to remove any residue or debris. For stubborn grime, use a mild solvent and ensure the tool is completely dry afterward.
• Lubrication: Periodically apply a light machine oil to the pivot points and moving parts to ensure smooth operation and prevent rust.
• Storage: Store the crimper in a dry environment to prevent corrosion. Keep it in its original packaging or a tool box to protect it from damage.
• Inspection: Regularly inspect the crimping jaws for wear or damage. Worn jaws can lead to poor crimps.

8. Troubleshooting

8.1 Common Issues and Solutions

• Poor Crimp Quality (Loose or Damaged):
  • Ensure the correct crimping slot is selected for the wire gauge and terminal type.
  • Adjust the crimping force using the adjustment dial (refer to Section 5.1).
  • Verify the wire is stripped to the correct length and fully inserted into the terminal.
  • Inspect the jaws for wear or damage; replace the tool if jaws are significantly worn.
• Ratcheting Mechanism Not Releasing:
  • Ensure the handles are squeezed completely until the mechanism clicks and releases.
  • Check for debris obstructing the ratchet mechanism; clean and lubricate if necessary.
• Difficulty Inserting Wire/Terminal:
  • Confirm the correct die size is chosen.
  • Ensure the terminal is properly aligned in the jaws before inserting the wire.
