Dust on the blade edge or 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 clamp cover is closed leaving an off-cut fiber on the
clamp, the rubber pad of clamp will have a trace of fiber,
causing loss of cleaving performance or poor quality of fiber
end face.
