5. Operating Instructions

The Gundlach No. 747 Double Stretcher Hook Attachment simplifies the carpet stretching process by allowing operation directly from the floor.

1. Prepare the Subfloor: Ensure the subfloor is a wood-based material (e.g., plywood, OSB) and is clean and free of any loose debris that could impede the hook's grip.
2. Position the Tool: Place the double prongs of the No. 747 attachment firmly onto the wood subfloor. The innovative design allows the tool to stretch from the floor, eliminating the need for wall-based leverage.
3. Engage the Stretch: Apply pressure to the stretcher head as you normally would, allowing the double prongs to securely grip the subfloor. This method provides a stable anchor point for effective carpet stretching.
4. Reposition as Needed: After each stretch, lift the tool, reposition it for the next section of carpet, and repeat the process.

The double prong design is specifically engineered to ensure the best grip in Oriented Strand Board (OSB) and similar subfloors, providing reliable performance without the need for additional support structures.

6. Maintenance

Proper maintenance will extend the life and performance of your Gundlach No. 747 Double Stretcher Hook Attachment.

• Cleaning: After each use, wipe down the attachment with a clean, dry cloth to remove any dust or debris. Avoid using harsh chemicals or abrasive cleaners.
• Inspection: Regularly inspect the prongs and the attachment mechanism for signs of wear, bending, or damage. Ensure all connections are secure.
• Storage: Store the tool in a dry environment to prevent rust and corrosion. Keep it away from direct sunlight and extreme temperatures.
• Lubrication: No specific lubrication is required for this attachment.

7. Troubleshooting

If you encounter issues while using your Gundlach No. 747 Double Stretcher Hook Attachment, consider the following common solutions:

• Poor Grip on Subfloor:
  • Ensure the subfloor is indeed wood (plywood, OSB). The tool is not designed for concrete or other non-wood surfaces.
  • Check for excessive debris or unevenness on the subfloor surface.
  • Verify that the prongs are not bent or worn.
• Attachment Feels Loose:
  • Ensure the attachment is properly secured to the stretcher head.
  • If using a Taylor stretcher, confirm that the necessary adapter tube is in place and correctly fitted.
• Difficulty Stretching:
  • Confirm that the tool is positioned correctly and firmly on the subfloor.
  • Ensure the carpet is properly prepared for stretching.
