1 The polishing thrust (pressure) varies according to the number of ferrules mounted in the holding
jig. Refer to section 3.3 for setting the thrust.
(3) Mount the ferrules in the holding jig evenly according to the explanation
given in section 4.1. When the ferrules are mounted incorrectly, the
ferrules can slip and the tips of the ferrules may not be polished correctly.
When mounting less than 12 ferrules in the holding jig, make sure they are
arranged in a balanced pattern, according to the explanation given in
section 4.1. An unbalanced arrangement of ferrules in the holding jig may
not be polished evenly.
