4. Setup
Changing Crimping Dies:
The Plustool crimping tool features easily interchangeable dies. Follow these steps to change them:
- Identify the two screws holding the current dies in place on the crimping tool.
- Use the provided screwdriver to loosen and remove these two screws.
- Carefully remove the existing dies from the tool.
- Select the appropriate new dies for your application (refer to Figure 3 for die types).
- Insert the new dies into the tool, ensuring they are correctly aligned.
- Reinsert and tighten the two screws securely to hold the new dies in place.

Adjusting Crimping Force:
The tool features an adjustable compression wheel to fine-tune the crimping force. If crimps are too loose or too tight, adjust the star wheel located near the pivot point. Turn clockwise for tighter crimps (more force) and counter-clockwise for looser crimps (less force). A small screw holds the adjustment in place.

It also shows the tool in use for various applications like motorcycle and automobile wiring.
5. Operating Instructions
Always ensure you select the correct die for your terminal type and wire gauge. Strip the wire insulation to the appropriate length, typically about a quarter of an inch, to ensure proper contact without exposing excess wire.
General Crimping Steps:
- Select the correct crimping die and install it on the tool.
- Open the crimping tool jaws.
- Insert the terminal into the appropriate slot on the die.
- Insert the stripped wire into the terminal.
- Squeeze the handles firmly until the ratcheting mechanism releases automatically, indicating a complete crimp.
- Inspect the crimp for tightness and proper formation.
Specific Terminal Types:
- Heat Shrink Connectors (AWG 22-10): Use Die A. After crimping, apply heat with a heat gun until the connector shrinks and seals around the wire. This is recommended for marine installations.
- Insulated Terminals & Nylon Terminals (AWG 22-10): Use Die B. Ensure the terminal is seated correctly before crimping.
- Non-Insulated Terminals (AWG 22-6): Use Die C. These terminals require a strong, secure crimp directly onto the bare wire.
- Open Barrel Terminals (AWG 20-10): Use Die D. Position the terminal so the open barrel is correctly aligned with the die for a secure, folded crimp.
- Ferrule Terminals & Insulated Cable End-Sleeves (AWG 24-8): Use Die E. Insert the ferrule onto the stripped wire, then crimp. The tool will pinch the plastic sleeve around the wire and crimp the metal ferrule.
- Solar Connectors (AWG 14-10): Use Die F. These specialized dies ensure a robust connection for solar applications.

Video 3: This video specifically demonstrates the crimping process for heat shrink connectors, showing how to crimp the terminal and then apply heat to shrink the insulation for a sealed connection.
6. Maintenance
- Cleaning: Keep the crimping tool and dies clean and free from debris. Wipe them down with a clean, dry cloth after each use.
- Lubrication: Periodically apply a light oil to the moving parts of the tool to ensure smooth operation.
- Storage: Store the tool and dies in the provided carrying case in a dry environment to prevent rust and damage.
- Inspection: Regularly inspect the dies for wear or damage. Worn dies can lead to poor crimps. Replace damaged dies as needed.
7. Troubleshooting
- Loose Crimps: If crimps are consistently loose, ensure the correct die is used for the wire and terminal. Adjust the compression wheel to increase crimping force (turn clockwise).
- Damaged Wires/Terminals: If the wire or terminal is damaged during crimping, check if the correct die is used and if the compression force is too high (turn compression wheel counter-clockwise). Ensure the wire is stripped to the correct length.
- Tool Jams: If the tool jams during crimping, use the quick-release lever to open the jaws. Inspect for any obstructions or misaligned components.
