the holding jig.
Step 5 Lift the weight arm lever up,
setting the thrust pin into the
hole in the center of the
holding jig.
4 - 10
NOTE
Make sure that the weight arm
lever goes to the full up position.
If it does not, the correct
polishing pressure will not be
applied to the holding jig and
polishing will not be performed
correctly.
Step 6 Set the timer to 1 min.
(standard).
Preparation for polishing is
complete.
NOTE
The first time a sheet of finishing
polishing film is used, the
polishing fluid will not completely
soak into the polishing film.
Therefore, when using a sheet of
finishing polishing film for the
first time, polish twice (1 minute
each).
Step 7 Press the ON button. The
polishing disk begins to rotate
and polishing begins.
NOTE
Press the OFF button if there is
any problem. The polishing disk
will stop rotating and polishing
will stop.
Step 8 The polishing will automatica lly
stop when the time set on the
timer is up. After the polishing
is completed, pull the weight
arm lever toward you and
remove the holding jig from the
polishing disk.

Water
NOTE
When removing the holding jig
from the polishing unit, lift the
holding jig up so the ferrules do
not touch the polishing film.
Step 9 Clean the holding jig and the
tips of the ferrules under
running water using the brush.
After cleaning, clean the brush,
removing all polishing grit or
other matter.
NOTE
There is no problem if washing is
done in the washing container,
but using running water is
preferred.
Step 10 Take the ferrules out of the
holding jig, undo the wire ties,
wash the ferrule tips with water
and dry the tips of the ferrules
with cleaning paper.
Step 11 Clean the ferrules with
cleaning paper and ethyl
alcohol. Clean the surface of
the polishing film with cleaning
paper and water.
NOTE
Do not leave any polishing fluid
on the polishing film because the
polishing fluid can dry on the
polishing film, scratching the
ferrules if the film is used again.
If polishing will not be done for a
period of time, keep the polishing
film immersed in water so that
any polishing fluid on it will not
dry.

4.6 POLISHING CONDITION CHECK
g
g
g
g
g
g
Check the condition of the ferrule tips after polishing. If there was a deep scratch
caused in the fiber during the adhesive removal step, satisfactory polishing cannot
be obtained. In this case, repolish.
NOTE
When repolishing ferrules that have an unsatisfactory polished condition,
polish from the grinding step to the finishing step to obtain consistent
polished quality.
(1) Speckles (2) Slight Scratch
Speckles
Repolish, doin
the polishing and
finishing steps.
Occurs near the end of the life of
the polishing film.
Occurs when the ferrule
mountin
in the holding jig is poor.
Slight scratch
Repolish, doing the polishing and
finishing steps.
Occurs when there is insufficient
cleaning between polishin
steps.
Occurs when you rub the tips of
the ferrules against the polishin
film when mounting the holdin
ji
to and removing it from the
polishing unit.

Scratch
Large scratch
(4) Polishing Fluid Remaining
Fiber scratch
Repolish, doin
the grinding,
polishing, and finishing steps.
Scratch was made during the
adhesive removal step.
Make sure you correctly follow
the
procedure for adhesive removal
(10 seconds with only the weight
of the jig, 20 seconds with 1 to 2
kg hand pressure).
Polishing fluid
Clean the tip of the ferrule. If you
cannot remove the polishing fluid,
do the finishing step again.
Clean the ferrules carefully after
every polishing step.

CHAPTER 5
MAINTENANCE
In order that the machine functions correctly, the following maintenance operations
must be carried out after completion of polishing operations.
5.1 CLEANING AFTER POLISHING
After finishing polishing, or when stopping polishing for a period of time, clean
the OFL-12 as well as all of the polishing films carefully with water. If no
cleaning is done, the remaining polishing fluid will harden. Also make sure
that no waterdrops remain on the operation panel.
When the OFL-12 won’t be used for a long time, ultrasonically clean the
holding jig in ethyl alcohol, then oil the holding jig and keep it in a vinyl
envelope.
5.2 CHANGING THE POLISHING FILM
The standard lifetime of a sheet of polishing film is 10 uses (120 ferrules
maximum) (for the abrasive paper for adhesive removal the lifetime is only
one use).
