2. Safety Information

Always prioritize safety when using any hand tool, especially those involved in electrical work. Failure to follow safety guidelines can result in serious injury or damage to equipment.

• Wear appropriate personal protective equipment (PPE): This includes safety glasses, gloves, and any other gear required by your work environment.
• Inspect the tool before each use: Ensure there are no signs of damage, wear, or loose components. Do not use a damaged tool.
• Ensure power is disconnected: Before working on any electrical conductors, verify that all power sources are de-energized and locked out according to safety protocols.
• Use the correct size and type of lug: Match the lug to the wire gauge and material (aluminum or copper) to ensure a secure and reliable connection.
• Keep hands clear of the crimping jaws: Avoid placing fingers or other body parts near the crimping mechanism during operation.
• Do not modify the tool: Any modifications can compromise the tool's integrity and safety.
• Store the tool properly: Keep the tool in a clean, dry place, away from children and unauthorized users.

4. Setup

Before beginning any crimping operation, ensure the tool is properly set up for the specific lug and wire size.

1. Identify Wire and Lug Size: Determine the exact AWG or MCM size of the wire and the corresponding lug to be used.
2. Adjust Indentor: Locate the adjustable indentor mechanism on the crimping head. Rotate the adjustment knob or lever to align the correct crimp size marking with the indicator. Refer to the markings on the tool for aluminum (ALUMI. TERMINALS) and copper (CU. TERMINALS) wire sizes.
3. Prepare Wire: Strip the insulation from the wire to the appropriate length, ensuring the conductor will fully enter the lug barrel without exposed strands after crimping.
4. Insert Wire into Lug: Fully insert the stripped wire conductor into the barrel of the lug.

5. Operating Instructions

Follow these steps to perform a proper crimp:

1. Open Tool Handles: Fully open the tool handles to separate the crimping jaws.
2. Position Lug: Place the lug barrel, with the wire inserted, into the crimping jaws. Ensure the lug is centered within the indentor and nest.
3. Initiate Crimp: Begin to close the handles slowly until the indentor makes contact with the lug barrel.
4. Complete Crimp: Apply firm and steady pressure to the handles, closing them completely until the crimp cycle is finished. The tool is designed to provide optimal crimping force when the handles are fully closed. The pull-out handle design assists in achieving the necessary leverage.
5. Inspect Crimp: After crimping, open the handles and remove the lug. Visually inspect the crimp for proper indentation and secure connection. The crimp should be uniform and the wire should be firmly held within the lug.
6. Repeat for Multiple Crimps: If the lug requires multiple crimps (e.g., for larger sizes), reposition the lug and repeat the crimping process for each required crimp location.

6. Maintenance

Regular maintenance ensures the longevity and reliable performance of your crimping tool.

• Cleaning: After each use, wipe down the tool with a clean, dry cloth to remove any dirt, dust, or debris. Pay special attention to the crimping jaws and indentor mechanism.
• Lubrication: Periodically apply a light coat of machine oil to all moving parts, including the pivot points and the indentor adjustment mechanism, to ensure smooth operation and prevent corrosion.
• Inspection: Regularly inspect the tool for any signs of wear, cracks, or damage to the handles, jaws, or frame. Check for any looseness in fasteners. If damage is found, discontinue use and contact Morris Products for service or replacement.
• Storage: Store the tool in a clean, dry environment, protected from extreme temperatures and moisture.

7. Troubleshooting

If you encounter issues while using the crimping tool, consider the following common problems and solutions:

• Poor Crimp Quality:
  • Cause: Incorrect indentor setting, improper wire stripping, or insufficient force applied.
  • Solution: Verify the indentor is set to the correct wire and lug size. Ensure the wire is stripped to the proper length and fully inserted. Apply full, firm pressure until the handles are completely closed.
• Difficulty Closing Handles:
  • Cause: Incorrect indentor setting (too small for the lug), foreign object in jaws, or lack of lubrication.
  • Solution: Check indentor setting. Inspect jaws for obstructions. Lubricate moving parts as per maintenance instructions.
• Handles Feel Loose or Wobbly:
  • Cause: Loose fasteners or worn pivot points.
  • Solution: Inspect all screws and pins. If any are loose, tighten them carefully. If wear is significant, the tool may require professional service or replacement.

If troubleshooting steps do not resolve the issue, contact Morris Products customer support for further assistance.
