5. Setup and Preparation

1. Clean the Surface: Ensure the application surface is thoroughly clean, dry, and free of dust, grease, or any contaminants. This is crucial for proper tape adhesion and vinyl application.
2. Plan Your Design: Carefully plan the desired cut line. The translucent nature of the tape allows for precise placement.
3. Unroll and Apply: Unroll a sufficient length of tape for your intended cut. Avoid touching the adhesive side excessively.

6. Operating Instructions

1. Apply the Tape: Lay the Knifeless Finish Line Tape directly onto the surface where you want to create a cut. Press firmly along the entire length to ensure good adhesion. The tape is highly flexible and can be curved to follow contours.

3. Activate the Cutting Filament: Locate the end of the visible filament (thread) at one end of the tape. Gently pull the filament upwards and away from the tape, parallel to the surface. The filament will cut through the vinyl film along the path of the tape.
4. Remove Excess Vinyl: Once the cut is complete, carefully remove the excess vinyl film from the area.
5. Remove the Tape: Peel off the Knifeless tape. It is designed to remove cleanly without leaving any adhesive residue on the surface or the newly cut vinyl.
6. Tips for Turns and Corners: When navigating sharp turns or intricate corners, ensure the tape is pressed down firmly to follow the contour. Pull the filament slowly and consistently to achieve a clean, continuous cut. Always leave sufficient extra length at the start and end of the tape to get a solid grip when pulling the filament.

7. Maintenance

Store the 3M Knifeless Finish Line Tape in its original packaging in a cool, dry place, away from direct sunlight and extreme temperatures. This helps maintain the adhesive quality and the integrity of the cutting filament. Keep the tape free from dust and debris to ensure optimal performance.

8. Troubleshooting

• Uneven Cuts: If cuts are uneven, ensure the tape was applied smoothly and firmly without kinks or bubbles. The filament should be pulled at a consistent speed and angle. Practice on scrap material can improve technique.
• Tape Not Adhering: Ensure the surface is completely clean and dry before application. Low temperatures can affect adhesive performance; ensure the tape and surface are at an appropriate working temperature.
• Residue Left Behind: While designed for no residue, ensure the tape is removed slowly and at a shallow angle. If residue occurs, it may be due to improper surface preparation or extreme environmental conditions.
• Filament Breaks: If the filament breaks during cutting, it may be due to pulling too quickly, at an incorrect angle, or encountering an obstruction. Start a new section of tape slightly overlapping the previous cut.
