1.0 Safety and Helpful Hints Use reagent grade isopropyl alcohol that is 99% pure to clean the fibers and other components. When terminating connectors on any cable containing grease, ensure that all grease is wiped away and the buffer, coating, and fiber are thoroughly cleaned with isopropyl alcohol. Isopropyl alcohol is not shipped with the 3M™ Field Termination Kits; however, a bottle for the alcohol is included.

9.0 9.1 Scribing Remove the 3M™ Hot Melt Connector from the 3M™ Universal Connector Holder if necessary. 9.2 Caution - Be careful so that you do not break the protruding fiber. 9.3 Position the scribe blade so the flat side of the blade is resting on the bead of adhesive and the blade is perpendicular to the fiber. Score the fiber by gently sliding the blade across the fiber just above the bead of adhesive. Scoring means that you are making a small scratch on the outside of the fiber.
10.0 Multimode Polishing: Hot Melt 10.2 Clean the round 3M Polishing Pad with a lint free cloth moistened with Isopropyl alcohol. 10.3 Place several drops of alcohol onto the round rubber pad. 10.4 Before the alcohol evaporates, place a sheet of the pale green, 2-micron 3M Lapping Film, shiny side down on the pad. The alcohol creates suction on the lapping film and helps hold it in place. 10.5 Clean the lapping film with a lint free cloth moistened with Isopropyl alcohol.

11.0 Singlemode Polishing: Hot Melt 11.2 Clean the round polishing pad with a lint free cloth moistened with Isopropyl alcohol. 11.3 Place several drops of alcohol onto the round rubber pad. 11.4 Before the alcohol evaporates, place a sheet of the pale green, 2-micron lapping film, shiny side down on the pad. The alcohol creates suction on the lapping film and helps hold it in place. 11.5 Clean the lapping film with a lint free cloth moistened with Isopropyl alcohol.
11.10 Remove the pale green, 2-micron 3M Lapping Film from the round polishing pad. 11.11 Clean the round 3M Polishing Pad with a lint free cloth moistened with Isopropyl alcohol. 11.12 Place several drops of alcohol onto the round rubber pad. 11.13 Before the alcohol evaporates, place a sheet of the frosted white final polish 3M Lapping Film, shiny side down on the pad. Note: Each sheet of frosted white final polish lapping film can be used for up to five connectors 11.
11.22 Good Polish (coaxial) 11.23 Good Polish (oblique) 23 11.
12.0 Finishing 12.1 Optional Step: For high stress situations, you may wish to apply a small amount of the 3M™ Pronto™ Instant Adhesive, CA-8 around the cable directly past the crimp ring, and at the end of the body of the ST Connector. Immediately install the strain relief boot. 12.2 3M™ Hot Melt ST Connector - Slide the strain relief boot onto the back of the connector. 12.3 3M™ Hot Melt ST Connector - If the connector is not to be immediately put into service, install the protective dust cap. 12.
