Operation Manual
IMPORTANT SAFETY PRECAUTIONS
This symbol indicates explanations about dangerous matters.
If users ignore this symbol and handle the cleaver the wrong
way, bodily injury and damage to the cleaver could result.
Caution
1. General
2. Structure
This product has been designed and manufactured to assure personal safety.
Improper use can result in bodily injury and serious damage to the fiber cleaver.
Please read and observe all warnings instructions given in this operation manual.
1
1. Do not disassemble or lubricate any parts of the cleaver. Doing so can cause
serious damage to the cleaver.
2. The FC-6S+ is a precision tool. Do not impact the cleaver by hitting or dropping
it. Doing so can cause personal injury and loss of cleaving performance.
3. Glass fiber fragments are extremely sharp. Handle with care. Wear safety
glasses at all times during cleaving operation for protection from glass fibers.
4. Dispose of glass fiber fragments properly. After use, please empty the off-cut
box and then store the cleaver in the case. There is a possibility that fiber offcuts
could spill out of the box during transportation if remain in the box.
5. The blade of the cleaver is extremely sharp. Do not touch it with bare hands.
6. The FC-6S+ has the “automatic blade return” function. When the clamp cover
is opened after cleaving, the blade carriage returns automatically to the forward.
Be careful not to be hit your fingers by the blade or blade carriage.
7. Do not impact the top clamp lever and switching lever. Doing so can cause
damage to the levers and loss of cleaving performance.
8. If the cleaver is damaged or a problem occurs, please contact our service
department.

< Fiber cleaver FC-6S+ >
1: Open the top clamp lever and the
lid of the single fiber adapter. The blade carriage
should be in the forward position. Lower the
fiber straight into the correct groove
with the end of the fiber coating at a mark to get a correct cleave length.
Top clamp lever
2: Close the lid of the single fiber adapter. Lower the top clamp
lever. Slide the blade
carriage to the rear of the cleaver. The fiber will be cleaved.
(When cleaving the
fiber of drop cable, hold the cable not to move around.) Open the top clamp lever
and the lid of the single fiber adapter. Lift the newly cleaved fiber. Lift the off-
cut
and dispose it properly. The blade carriage returns
automatically after cleave,

4. Maintenance
Cleaning
Blade height adjustment
Remove the fiber off-cut box first.
1: Loosen the 2 cross head screws.
2: Slide the blade carriage to the rear of the cleaver,
then loosen the blade height locking screw.
Put a Hex driver (US) or
Allen key (UK) here.
Blade height locking screw

To keep excellent cleaving quality, cleaning must be performed after use.
Clean the blade edge, the rubber pad of the clamp and the anvil with a cotton
swab moistened with isopropyl alcohol.
Cotton swab
Clean the fiber holder receptacle
and the grooves of the single
fiber adapter, too.
Caution
▪
Dust on the blade edge or the clamp might cause loss of cleaving
performance or poor quality of fiber end face.
▪ Do not clean them with any other kind of chemicals.
▪ If the top clamp lever is closed leaving an off-
cut fiber on the clamp,
the rubber pad of the clamp will have a trace of the fiber, causing
loss of cleaving performance or poor quality of fiber end face.
Blade position change
As the number of the cleave
’s
increases, a symptom that fiber cannot be cleaved
or cracks will occur. If such symptom continues to appear, the blade position is
worn out. Rotate
the
blade according to the following procedures and use a new
blade position.
[Reference] 2,250 fibers per position (*)
(*) The number above is not guaranteed. It may vary depending on the operating environment.
Remove the fiber off-cut box first.
1:
Loosen the blade setscrew with a
slotted screwdriver.
2:
Rotate the blade to the next position by pressing its side or edge with a cotton
swab. Cotton swab
Rotate the blade in the direction
indicated by the arrow.
▪ Do not rotate the blade with hands.
▪ Do not rotate the blade with metallic tweezers. Doing so may
damage the blade.
Caution
3: Tighten the blade setscrew.
[Reference] Optimum torque:
Approx. 0.98N∙m (10kgf∙cm)
▪ Do not over-tighten the blade setscrew. The screw will get
worn out.
Caution
4: Try and cleave the fiber. Make visual check of the fiber end face with the splicer.
If the fiber end face is poor, adjust the blade height. (Refer to “
Blade height
adjustment”.)
3: Place a mechanical pencil lead or a light stick on the
clamps. Slide the blade
carriage back and forth and turn the blade height adjustment screw.
The point
where the lead barely touches the edge of the blade is a reference point (0μm).
Tips
▪ To make the blade higher, turn the blade height adjustment screw clockwise.
▪ To make the blade lower, turn the blade height adjustment screw anti-
clockwise.
(Turn the screw while pushing the blade down with a cotton swab.)

4: Turn the blade height adjustment screw clockwise by more 4 to 6
marks from the
reference point.
Caution
▪
Do not make the blade too high. Doing so will damage the anvil
and increases the chipped fiber ends.
5: Tighten the blade height locking screw.
[Reference] Optimum torque: Approx. 0.59N∙m (6kgf∙cm)
6: Tighten the 2 cross head screws.

Blade replacement
2: Remove the blade with tweezers.
Tweezers
▪
The edge of a blade is manufactured precisely. If the edge is hit
against metallic objects, it will crack, resulting in poor cleaving
performance. Handle with care.
▪ When using metallic tweezers, be careful not to damage the blade.
▪ Do not touch the blade with hands. Use gloves.
▪ Dispose of the old blade properly.
