4. Setup
Installing/Changing Jaws:
The crimping tool features a simple mechanism for changing jaws, allowing for quick adaptation to different terminal types.
- Identify the two small screws on the side of the crimper head that secure the jaws.
- Use the included cross screwdriver to loosen and remove these screws.
- Carefully remove the currently installed jaws.
- Select the appropriate jaw set for your application (refer to Section 3).
- Align the new jaws with the crimper head, ensuring they fit snugly into their designated slots.
- Reinsert and tighten the two screws firmly to secure the new jaws in place. Do not overtighten.

5. Operating Instructions
Using the Ratchet Crimping Tool:
The ratchet mechanism ensures a complete crimp cycle for reliable connections.
- Select the correct jaw set for your terminal and wire gauge.
- Insert the terminal into the appropriate slot in the crimping jaws.
- Gently squeeze the handles until the ratchet mechanism holds the terminal in place.
- Insert the stripped wire into the terminal.
- Continue squeezing the handles firmly until the ratchet mechanism fully cycles and releases, indicating a complete crimp.
- Remove the crimped terminal.

Using the Wire Stripper:
The included wire stripper is designed for efficient and damage-free insulation removal.
- Identify the correct stripping hole on the wire stripper for your wire's AWG (American Wire Gauge).
- Insert the wire into the corresponding stripping hole.
- Close the handles firmly, applying even pressure. The precisely machined hole will cut through the insulation.
- Pull the wire stripper away from the wire to remove the insulation, leaving the conductor exposed.
- Use the cutting edge near the pivot for cutting wires if needed.

6. Maintenance
- Cleaning: After each use, wipe down the tools with a clean, dry cloth to remove any dirt, dust, or debris. For stubborn grime, a mild cleaner can be used, ensuring the tools are thoroughly dried afterward.
- Lubrication: Periodically apply a light machine oil to the pivot points and moving parts of the crimping tool and wire stripper to ensure smooth operation and prevent rust.
- Storage: Store the tool set in its original carrying case in a dry environment to protect it from moisture and physical damage. Ensure all jaws and the screwdriver are securely placed in their designated compartments.
- Inspection: Regularly inspect the jaws for wear or damage. Worn jaws can lead to improper crimps. Replace damaged components as necessary.
7. Troubleshooting
- Improper Crimps (Too Loose/Too Tight):
- Ensure you are using the correct jaw set for the specific terminal and wire gauge.
- Verify that the wire is fully inserted into the terminal before crimping.
- Check the adjustable compression wheel on the crimper (Figure 4.2). Adjust it to increase or decrease crimping force as needed.
- Ensure the ratchet mechanism completes its full cycle. If it's not, check for obstructions or excessive wear.
- Difficulty Releasing Crimped Terminal:
- The tool has a built-in quick release gear (Figure 4.2). If the crimp is stuck or the tool doesn't release automatically, activate the quick release lever.
- Ensure the jaws are clean and free of debris that might impede release.
- Wire Stripper Not Cutting/Stripping Cleanly:
- Ensure you are using the correct stripping hole for the wire's AWG.
- Inspect the stripper blades for dullness or damage.
- Apply firm, even pressure when stripping.
