protection along the fi ber until it fully covers the splice
area. The process fi nal step will be to introduce this heat-
shrink protector into the “HEATER” of the equipment by
pressing the “HEAT” key, as long as the automatic heating
option is not activated.
Bear in mind that while the heater’s red LED is on, the
heater is near its maximum operating temperature.
When this LED turns off (a beep will be produced), the
temperature will have reached its maximum value, but
the process will still be on-going. Wait until you hear
a second beep (indicating the oven has reached its
minimum temperature), to take the tube out of the heater
and place it on the cooler tray.
It is likely that the equipment’s internal fans turn on while
the heater is being used .
This process manages the temperature of the heater’s
components to enhance durability .
6. Maintenance
6.1 V-groove
Clean the V-groove.
In most cases, splice fusion high losses are caused by
the presence of contamination (residues/dirt) on the
V-groove. Therefore, you will need to clean both by
following the steps below:
1 Open the protective cover .
2 Clean the V-grooves using specifi c cleaning swabs (Ref .
232710), dampened with isopropyl alcohol .
3 Should the dirt be adhered, you can use a stripped clean
fi bre to push it out (put the fi ber and V-groove forming a
45o angle with each other) .
Note: Apply a controlled force for the cleaning of the
V- groove. It is a sensitive precision element.
6.2 Cameras or lenses
Clean the lenses regularly.
Presence of dirt on the lenses will result in splicing fusion
problems. Therefore, you should periodically inspect the
lenses and clean them if necessary, by following the steps
below:
1 Open the protective cover.
2 Clean both lenses using a specifi c swab (Ref. 232710)
dampened with isopropyl alcohol, by drawing circles
progressively increasing in diameter (start from the
center outwards) .
3 Use a dry swab to get rid of possible residues and have
the lenses fully dried .
4 Make sure no residues are left on the surface of the
lenses after cleaning .
Note: During the cleaning, be careful not to push or hit
the electrodes . Apply a controlled force (lenses are very
sensitive elements). Excessive pressure could result in
scratches, that would make the lenses unusable.
6.3 Changing the cleaver’s cutting blade
position
The cleaver’s cutting blade has 23 positions. Each position
can execute 1,000 cutting operations, which means 23,000
cuts per blade.
As long as the cleaver operates correctly, do not modify
the blade’s position, even if more than 1,000 cuts have
been performed. You should only modify the blade’s
position if you observe that despite its height being
correct, the blade is not able to cut.
Follow the steps below to modify the blade’s position:
1 Remove the fi bers deposit loosening the screw indicated
in the picture below:
