- Clean the sealing surface, remove old sealing remains, and check for

damage.

- After the sealing surface is cleaned and fat-free, position the sealant

tape in the middle of the sealing surface.

- When applying the sealant tape, progressively remove the adhesive

protective tape. Make sure that the adhesive is not soiled or damaged

during installation, this can influence the positioning of the tape.

- Position the end of the sealant tape around the starting bolt hole.

Complete the installation by overlapping both ends of the sealing tape at 

the starting bolt hole, ant cut away any excessive material.
