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
bin and then store the cleaver in the case. There is a possibility that fiber offcuts
could spill out of the bin during transportation if remain in the bin.
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.

2: Lower the
fiber straight into the
correct V-
groove with the end of the
fiber coating (e.g. if the cleave
length is 16mm) at the 16mm mark
on the ruler.
3:
Close the lid of the single fiber
adapter.
4: Lower the
top clamp lever. Slide the blade carriage to the rear of the cleaver.
The fiber will be cleaved.
5:
Open the top clamp lever. Then open the lid of the single
fiber adapter and lift the newly cleaved fiber. Lift the off-
cut
and dispose it properly. (The FC-6S+
automatically
collects an off-cut in the off-cut collector.)

Lower the top clamp lever. Slide the blade carriage to the rear of the cleaver.
The fiber will be cleaved.
4: Open the top clamp lever. Remove the fiber holder from the cleaver. Lift the off-
cut and dispose it properly. (The FC-6S+ automatically collects an off-
cut in the
off-cut collector.) T
he blade carriage returns automatically after cleave, please
refer "Automatic blade return function".
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.

4. Maintenance
Cleaning
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.
Remove the off-cut collector 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”.)
Automatic blade return function
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.

Blade height adjustment
Remove the off-cut collector 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.

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.
[Reference] Optimum torque: Approx. 0.98N∙m (10kgf∙cm)
Blade replacement
Remove the off-cut collector first.
1: Unscrew the blade setscrew.
2: Remove the blade with tweezers.
Tweezers
Caution
▪
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.
3: Insert a new blade in the cleaver so that “(1)” of the number sticker
is in the top
position. (Refer to the enlarged view below.)
The hole of the blade should be aligned with the hole of the blade receptacle.
