Installation Instructions
Follow these steps to replace your roller blind belt using the Band-fix repair set:
- Prepare the Roller Blind: Lower the roller blind completely. If possible, unroll the old belt until its attachment point to the roller shaft inside the casing is visible.
- Cut the Old Belt: Identify the worn or damaged section of the old roller blind belt. Using strong scissors, cut the old belt cleanly at the point where the repair will be made.
- Attach the New Belt: Take the new roller blind belt from the kit. Use the provided stainless steel connecting strip and rivets to securely attach the new belt to the existing old belt. Ensure the connection is firm and straight. The mandrel can be used to punch precise holes for the rivets.
- Secure the Connection: Once the new belt is riveted to the old one, apply the adhesive tape strip over the connection point. This provides additional stability and a smoother transition, helping the belt move freely through the guide.
- Test and Adjust: Carefully raise and lower the roller blind to ensure the new belt moves smoothly and the repair holds. If the belt appears twisted, you may need to carefully unscrew the belt winder from the wall and rotate it to correct the twist before re-securing.
- Address Guide Obstructions: If the repaired section does not pass smoothly through the upper guide, gently cut the sides of the repair piece open slightly and bend it to allow for easier movement.

Maintenance
To ensure the longevity and smooth operation of your roller blind belt and the repair, consider the following maintenance tips:
- Regular Inspection: Periodically inspect the roller blind belt for any signs of wear, fraying, or damage, especially near the repair point.
- Keep Clean: Ensure the belt and its guide channels are free from dust, dirt, and debris, which can cause friction and wear.
- Gentle Operation: Operate your roller blind smoothly and avoid sudden jerks or excessive force, which can stress the belt and its components.
Troubleshooting
- Problem: The roller blind belt appears twisted after installation.
Solution: Carefully unscrew the belt winder from the wall. Rotate the winder to correct the twist in the belt, then re-secure it to the wall. - Problem: The repaired section of the belt does not pass smoothly through the upper guide.
Solution: The metal connecting strip might be slightly too rigid. Gently cut the sides of the adhesive tape strip open and carefully bend the metal strip slightly to allow for easier movement through the guide. - Problem: The new belt does not attach securely to the old belt.
Solution: Ensure that the rivets are properly inserted and fastened. If the connection feels loose, re-evaluate the riveting process or ensure the belt ends are aligned correctly before riveting.
