When air leakage is found, please confirm the following points:

1. Circle the puncture part of the tire and pull out the puncture.

2. Probe the puncture penetration direction with the puncture probe, insert and pump along the puncture direction to remove dust and debris inside the puncture.

3. Cut one end of the rubber strip into a diagonal opening and put it through the hole in the front end of the inserting tool, so that the length of the rubber strip at both ends of the hole is basically the same.

4. Insert the needle with rubber strip into the tire along the puncture hole to ensure that the rubber strip is inserted 2/3 of the length(it must be confirmed that the cold patch strip penetrates the tire body to avoid slipping out after inflation),Rotate the needle 360 degrees and pull out the needle.

5. Cut off the rest of the rubber strip that is left on the tire, leaving a length of 5mm on the tread
