5. Operating Instructions

Follow these steps for proper crimping of wire ferrules:

1. Prepare the Wire: Strip the insulation from the end of the wire to the appropriate length for the ferrule being used. The stripped length should match the metal tube length of the ferrule.
2. Insert Wire into Ferrule: Insert the stripped end of the wire completely into the ferrule. Ensure all wire strands are contained within the ferrule's metal tube.
3. Select Crimping Profile: Identify the correct crimping profile on the pliers that matches the size of your wire ferrule. The pliers feature multiple profiles for different ferrule sizes (e.g., 1.5, 2.5, 4, 6, 10, 16 mm²).
4. Position Ferrule: Place the ferrule, with the wire inserted, into the selected crimping profile of the pliers. Ensure the ferrule is seated firmly and squarely within the jaws.

Figure 2: The image shows a wire ferrule with a green and yellow wire inserted into the crimping jaws of the pliers, ready for crimping. The ferrule is positioned in the appropriate size slot.
5. Perform Crimping: Squeeze the handles of the pliers firmly and completely until the crimping action is finished. The pliers are designed to apply the correct pressure for a secure crimp.

6. Inspect Crimped Connection: After crimping, release the handles and remove the ferrule. Visually inspect the crimp for proper formation. The ferrule should be securely fastened to the wire, and the wire strands should not be visible or loose. A gentle tug test can confirm the connection's integrity.

6. Maintenance

• Cleaning: After each use, wipe the pliers clean with a dry cloth to remove any dirt, dust, or debris. For stubborn grime, a slightly damp cloth can be used, followed by thorough drying.
• Lubrication: Periodically apply a small amount of light machine oil to the pivot points to ensure smooth operation and prevent rust.
• Storage: Store the pliers in a dry environment to prevent corrosion. Keep them away from corrosive chemicals.

7. Troubleshooting

If you encounter issues during operation, consider the following:

• Poor Crimp Quality:
  • Ensure the correct crimping profile is selected for the ferrule size.
  • Verify the wire is fully inserted into the ferrule and all strands are captured.
  • Apply sufficient pressure by fully closing the pliers handles.
• Difficulty Squeezing Handles:
  • Check if the correct ferrule size is used for the selected crimping profile. Using an oversized ferrule can make crimping difficult.
  • Lubricate the pivot points if the pliers feel stiff.
