4. Product Overview
4.1 Hexagonal Ferrule Crimper
The ferrule crimper features an upgraded jaw design with built-in stoppers to prevent over-closure, ensuring consistent and reliable hexagonal crimps. It includes an efficient ratchet mechanism, adjustable crimping force, and a quick-release function for ease of use. The ergonomic non-slip handle provides comfort during prolonged operation.

4.2 Wire Stripper
The included wire stripper is designed for precise and effortless insulation removal. It features sharp, adjustable blades suitable for multi-strand wires, single-core wires (0.2-6mm²), 2-8pin ribbon cables, and coaxial cable jackets (0.75mm²). This tool enhances efficiency by ensuring clean and accurate stripping without damaging the wire conductors.

4.3 Ferrule Connectors
The kit contains 1660 insulated ferrule connectors in 16 different sizes, ranging from AWG 28 (0.08mm²) to AWG 5 (16mm²). These ferrules are color-coded for easy identification and selection, providing versatility for a wide range of electrical applications.
5. Setup
Before first use, unpack all components from the portable carry case. Inspect each tool and the ferrule connectors for any signs of damage. Familiarize yourself with the layout of the ferrule assortment in the case. Ensure the work area is clean and well-lit.
6. Operating Instructions
6.1 Using the Wire Stripper
- Adjust Stripping Length: Use the adjustable stopper on the wire stripper to set the desired stripping length. This ensures consistent strip lengths for ferrule application.
- Insert Wire: Place the wire into the appropriate stripping slot.
- Strip Insulation: Squeeze the handles firmly to cut and remove the insulation. The stripper will automatically adjust to the wire gauge.
- Wire Cutting: The stripper also includes a wire cutting function. Insert the wire into the cutting blades and squeeze the handles.
- Wire Twisting: For stranded wires, the stripper can assist in twisting the exposed strands together for easier ferrule insertion.
6.2 Using the Ferrule Crimper
- Prepare Wire: Strip the wire insulation to the appropriate length for the chosen ferrule. The exposed conductor should fill the metal tube of the ferrule without insulation entering the crimp area.
- Select Ferrule: Choose the correct size ferrule connector that matches the wire gauge (AWG/mm²). Refer to the ferrule assortment chart in the case for guidance. The kit provides two lengths per gauge for maximum versatility.
- Insert Wire into Ferrule: Fully insert the stripped wire conductor into the metal tube of the ferrule. Ensure all strands are contained within the ferrule.
- Position Ferrule in Crimper: Open the crimper handles and insert the ferrule (with wire) into the hexagonal crimping jaws. Ensure the ferrule is seated correctly and centered.
- Crimp: Squeeze the crimper handles firmly until the ratchet mechanism releases. This ensures a complete and secure hexagonal crimp. The crimper applies uniform force on six sides for a perfect hexagon shape.
- Inspect Crimp: After crimping, gently pull on the wire to ensure the ferrule is securely attached and the crimp is uniform. The copper wire should fill at least 70% of the terminal for optimal connection.


7. Maintenance
- Cleaning: After each use, wipe down the crimper and wire stripper with a clean, dry cloth to remove any dust, debris, or wire fragments.
- Lubrication: Periodically apply a light machine oil to the moving parts and pivot points of the tools to ensure smooth operation and prevent rust.
- Storage: Store the entire kit in its original portable carry case in a dry, cool place, away from direct sunlight and moisture. Ensure all components are securely placed in their designated compartments to prevent loss or damage.
- Inspection: Regularly inspect the crimping jaws and stripper blades for wear or damage. Replace tools if significant wear or damage is observed to maintain performance and safety.
8. Troubleshooting
- Poor Crimp Quality:
- Ensure the correct ferrule size is used for the wire gauge.
- Verify the wire is fully inserted into the ferrule before crimping.
- Ensure the crimper handles are fully squeezed until the ratchet releases.
- Wire Slipping from Ferrule:
- Check if the wire was stripped to the correct length. Too short a strip may result in insufficient contact.
- Ensure the crimper was fully engaged and the ratchet mechanism completed its cycle.
- Wire Stripper Not Cutting/Stripping Cleanly:
- Check if the blades are clean and free from debris.
- Ensure the wire is placed in the correct stripping slot for its gauge.
- The blades may be worn and require replacement (if applicable) or the tool may need replacement.
- Crimper Jaws Jamming:
- This model features built-in stoppers to prevent jamming. If jamming occurs, ensure no foreign objects are obstructing the jaws.
- Do not attempt to force the jaws open or closed. Use the quick-release function if available.
