1. General
1.1 The Corning Cable Systems FBC-005 high precision fiber
cleaver mechanically produces right-angle end-cuts in single-
mode and multimode silica glass fibers with an outside diameter
of 100-140 µm.
1.2 The FBC-005 operates on a bend-and-scribe principle. The
fiber is bent over an anvil by two pairs of clamps, tightened until
it is taut, and scribed by a diamond blade. The tightening and
scribing actions cause the fiber to break, resulting in a
precise right-angle cleave (Figure 2).
Figure 2
1.3 This issue includes an updated title.

Safety Glasses
WARNING: The wearing of safety glasses to protect the
eyes from accidental injury is strongly recommended when handling
chemicals and cleaving fiber.
Isopropyl Alcohol
DANGER: Flammable. Flashpoint below 73° F. Keep
away from heat, spar s and open flame. Can cause irritation to eyes
on contact. In case of eye contact, flush eyes with water for at least 15
minutes. Inhaling fumes may induce mild narcosis. In case of
ingestion, consult a physician.
DANGER: Cleaved glass fibers are very sharp and can
pierce the s in easily. Do not let cut pieces of fiber stic to your cloth-
ing or drop in the wor area where they can cause injury later. Use
tweezers to pic up cut or bro en pieces of the glass fibers and place
them on a loop of tape ept for that purpose alone. Good house-
keeping is very important.

5. Cleaver Maintenance
Cleaver Cleaning
5.1 After each day’s use, clean the guides, clamping pads,
cutting blade, and anvil of the FBC-005 cleaver as follows:
(a) Clean the clamping pads by inserting a cleaning strip
soaked in alcohol between the pads and pressing down
on the cleaver to close them. Pull the strip from between
the pads (Figure 7). Repeat this step several times.
Repeat this step several times with a clean, dry strip.
Complete the cleaning by blowing the pads with
compressed air.
Figure 7
Cleaning of the anvil and clamping pads may be followed
by polishing. Polishing these components is recommend-
ed if a number of fibers have broken between the clamps.
Repeat the cleaning steps above, substituting a dry (no
alcohol) 3 mm or finer lapping film, to polish both the
upper and lower fiber clamps and the anvil. Then repeat
with a dry paper strip to remove any residue.Polishing
may performed on a weekly or as-needed basis.
(b) To clean the diamond cutting blade, insert a cleaning
strip soaked in alcohol between the anvil and the cutting
blade. ift the cleaning strip up to the blade and brush
along and down the blade at an angle.
Complete the cleaning by blowing the blade with
compressed air.
(c) Carefully inspect the cleaver for any fiber remnants, bits of
dirt, etc. Repeat steps a and b if necessary.
Lubricating the FBC-005
5.2 The FBC-005 should be lubricated every three months and
before extended periods of storage. ubrication on a regular basis
will help assure you high quality fiber end-cuts with each use of
the cleaver. The cleaver may be used during the lubrication pro-
cedure.
5.3 Place one drop of synthetic oil (P/N FBC-005-02) on each
side of the pivot pin (Figure 8).
Figure 8
5.4 Press the cleaver cover down about ten (10) times, and
place another drop of oil on both sides of the pivot pin.
5.5 Wipe off all excess oil from the outer body of the cleaver.
Issue 11 SRP-001-055 Page 3
IMPORTANT: Most cleaver problems can be
prevented through proper cleaning on a regular
basis. Debris in the mechanism will result in poor
performance.

Blade Adjustment and Replacement
5.6 If your cleaver stops making acceptable cuts, try increasing
the fiber tension by using the switch on the back of the cleaver.
The switch rotates in a clockwise direction from "Standard" (5
oz) to “+ 0,4 N" (6.4 oz.) (Figure 9).
Figure 9
Use a step-up, trial and error procedure when increasing the fiber
tension. For example, use the small slotted screwdriver to turn
the switch form its “Standard” 9 o’clock position until its mark is
at a 10 o’clock position. Use the cleaver and make a splice. If no
improvement is noted, turn the switch to the 11 o’clock position,
make a splice etc., until optimum setting is found.
5.7 Corning Cable Systems recommends factory service for
blade replacement and adjustment. The following procedure is
provided should it be necessary to replace the cutting blade in the
field.
5.8 Remove the slotted screwdriver and blade replacement tool
from the cleaver case. Use a cotton-tipped swab to position the
blade arm as shown in Figure 10. Position the tool on the blade.
Figure 10
5.9 Release the cutting blade retaining screw with the slotted
screwdriver and withdraw the blade from the cleaver. Ta e care not
to misplace the screw.
5.10 Place the new cutting blade into the tool (Figure 11).
Figure 11
5.11 Insert the retaining screw into the hole of the replacement
blade.
5.12 Position the replacement blade in the cleaver, lining up
the screw with the threaded hole. During positioning, use the
tool to press the replacement blade upwards and back against the
stop pin (Figure 12 inset).
5.13 Tighten the retaining screw with the slotted screwdriver
(Figure 12). Remove the swab from the blade arm.
Figure 12
5.14 Make trial cuts after replacing the blade to make sure
the cleaver is working properly. If the blade pushes the fiber out
of position, the front edge of the blade is positioned too low.
oosen the screw and repeat steps 5.12 and 5.13.

Vertical Spring Replacement
5.15 If the cleaver's vertical spring is worn, broken, or disfig-
ured, use the following steps to replace the spring.
5.16 Remove the cleaver back plate by removing the single
slotted screw (see Figure 13)
5.17 Remove the cleaver cover by removing the two slotted
screws. ift the cover straight off the cleaver, taking care not to
bend the small post which projects from inside the cover
(Figure 13).
5.18 Remove the parts of the broken vertical spring (Figure14).
If the spring is merely worn or disfigured and still attached to the
horizontal posts, use a hook spring tool to unhook the spring
from the top horizontal post.
5.19 If necessary (typically on units with serial numbers
< 1000), insert a small punch or dowel into one of the lower hori-
zontal post access holes of the cleaver.
Gently tap on the post until there is just enough space to remove
the lower end of the new spring on the post
(Figure 15). If still present, slide the bottom end of the old spring
off the post. The lower posts on newer FBC-005s do not extend across
the access space and therefore do not require the use of a dowel or punch
to move them.
Figure 15
5.20 ower the new spring from above and behind the
horizontal spring and secure it to the lower post.
Insert the dowel in the opposite post access hole and gently tap it
back into place. Center the end of the spring on the lower post.
5.21 Use the hook spring tool to lift and set the top of the
new spring into the groove in the upper horizontal post
(Figure 16).
5.22 Reinstall the cleaver cover on the unit, carefully aligning
both of the screw holes and the post inside the cover with proper
holes in cleaver assembly. Secure the cover with the two slotted
screws removed in step 5.17.
5.23 Replace the back plate on the cover and secure with
the remaining slotted screw. When properly installed, there is no
friction in the normal movement of the cleaver.
