PART 4

CAUTION:
When working with FIPG material, perform the following:

* Using a razor blade and gasket scraper, remove all the old FIPG material from the gasket surfaces.
* Thoroughly clean all components to remove any loose material.
* Clean both sealing surfaces with a non-residue solvent.
* Apply FIPG in a continuous line (width approximately 1 mm (0.0394 in.)) along the sealing surface.
* Parts must be assembled within 10 minutes of application. Otherwise, the FIPG material must be removed and reapplied.
