3. Installation Instructions

Replacing the cutting head is a straightforward process. Always ensure the paper trimmer is stable and unplugged if it has electrical components before proceeding.

1. Preparation: Place the paper trimmer on a flat, stable surface.
2. Locate Fasteners: Identify the screws or clips securing the existing cutting head to the guide bar. Typically, there are two screws.

4. Install New Head: Slide the new Dahle 647 Cutting Head onto the guide bar, ensuring it is correctly oriented.
5. Secure Head: Re-insert and tighten the screws or re-engage the clips to firmly secure the new cutting head in place. Do not overtighten.

4. Operation

Once installed, the Dahle 647 Cutting Head operates as an integral part of your Dahle Roll- and Cut paper trimmer. Its rotary blade design allows for smooth, precise cuts when guided along the trimmer's cutting edge. For detailed operating instructions of your specific paper trimmer model, please refer to the original manual provided with your Dahle Roll- and Cut device.

5. Maintenance

To ensure the longevity and optimal performance of your Dahle 647 Cutting Head:

• Cleaning: Periodically clean any paper dust or debris from around the cutting head and guide bar using a soft brush or cloth.
• Blade Sharpness: The cutting head contains a self-sharpening rotary blade. However, over time and with extensive use, the blade may become dull. If you notice frayed edges or difficulty cutting, it is time to replace the cutting head.
• Storage: When not in use, store the paper trimmer in a clean, dry environment to prevent dust accumulation and potential damage.

6. Troubleshooting

• Poor Cut Quality (Frayed Edges, Incomplete Cuts):

  This typically indicates a dull blade. Replace the cutting head with a new Dahle 647 unit.

• Cutting Head Does Not Slide Smoothly:

  Check for any obstructions or debris on the guide bar. Ensure the cutting head is properly seated and the fasteners are not overtightened. Clean the guide bar thoroughly.

• Cutting Head Does Not Fit:

  Verify that your paper trimmer model is listed under the compatibility section (Dahle 550, 552, 554) and that its metal guide bar has a 20mm diameter. If your model differs, you may require a different Dahle cutting head.
