4. Setup

1. Select Components: Ensure you have the correct Greenlee punch and draw stud that match the 14722 die for the desired hole size.
2. Prepare Workpiece: Mark the center of the desired hole location on the metal material. Drill a pilot hole at this mark. The pilot hole size must be appropriate for the draw stud being used.
3. Assemble Punch and Die:
   • Insert the draw stud through the pilot hole from the side of the material where the punch will be placed.
   • Thread the punch onto the draw stud on one side of the material.
   • Thread the 14722 die onto the draw stud on the opposite side of the material, ensuring the cutting edge faces the material.
4. Connect Driver: Attach your chosen driver (manual, ratchet, hydraulic, or battery-powered) to the draw stud.

5. Operating Instructions

1. Secure Workpiece: Ensure the material is firmly held in place to prevent shifting during the punching process.
2. Align Components: Verify that the punch, die, and draw stud are correctly aligned and centered over the pilot hole.
3. Engage Driver: Operate the driver according to its specific instructions. Apply steady, even pressure to draw the punch through the material.
4. Complete Punch: Continue operating the driver until the punch fully cuts through the material and the slug falls into the die.
5. Remove Slug: Once the hole is cut, loosen the draw stud and remove the punch and die. The slug will typically fall free from the die with a quick tip.
6. Inspect Hole: Check the newly punched hole for cleanliness and accuracy.

6. Maintenance

• Cleaning: After each use, clean the die and punch to remove any metal shavings or debris. A stiff brush or compressed air can be used.
• Lubrication: Apply a light coat of oil to the cutting edges of the die and punch to prevent rust and ensure smooth operation.
• Inspection: Regularly inspect the die for signs of wear, dullness, or damage to the cutting edge. A dull die can lead to poor cuts and increased effort.
• Storage: Store the die in a clean, dry place to protect it from moisture and corrosion.

7. Troubleshooting

Common Issues and Solutions:

• Poor Cut Quality / Burrs:
  • Ensure the punch and die are correctly aligned and tightened.
  • Check if the die or punch is dull or damaged; replace if necessary.
  • Verify the material thickness is within the tool's specified capacity.
• Difficulty Clearing Slugs:
  • Ensure the slug falls freely into the die. If using a Slug-Buster system, verify its proper function.
  • Clean any debris from the die cavity.
• Excessive Force Required:
  • Lubricate the draw stud threads.
  • Check for dullness or damage to the punch and die.
  • Confirm the material thickness is not exceeding the tool's capacity.
