17.7Clean the flat side of the polishing jig with a lint-free cloth moistened with isopropyl alcohol.

17.8 Place the polishing jig assembly on the lapping film.

17.9Place the ferrule in the polishing jig aligning the latch side of the connector with the slot until it stops.

Note: The ferrule must be able to slide freely inside the hole in the polishing jig. If not, the ferrule may have adhesive on it which needs to be cleaned off with alcohol and a lint- free cloth.

17.10Insert the polishing weight into the adapter/jig assembly covering the connector.

Note: The weight should pop up slightly (1/16") when holding the jig flat against the lapping film, indicating that the ferrule can move freely.
