How to use

Locate the puncture by inflating the tube and listening or using water to find air bubbles, then dry and mark the damaged area. Use the included preparation tool to roughen and clean the tube surface around the puncture, apply adhesive patch according to the patch instructions and press firmly until set. If valve servicing is needed, use the valve tool to remove or tighten the valve core. Use the mounting tools and wrench to remove and reinstall the wheel or to pry the tire bead off and back on when accessing the tube. Follow standard safety precautions: work on a stable surface, avoid sharp contact with tools and verify that the repair holds by partially reinflating and inspecting before full inflation and riding.

Usage recommendations

Store the kit in a dry place and keep adhesive patches sealed until use. For longer-lasting repairs, ensure the tube surface is clean and dry before applying patches and allow the adhesive to cure. Replace patches or tools that show wear; use appropriate tire pressure after repair and inspect the tire casing for embedded objects before reuse.
