Operation
1. Open the fiber clamp mechanism and pull the fiber cleaving wheel
mechanism back toward yourself.
2. Place the fiber to be cleaved in the desired fiber adapter.
Load
900 micron
fiber into the
adapter so that
the buffer is
flush with the
end of the
adapter.
Hint: It is easier to load the fiber into the adapter if the fiber is curled in a
downward direction from the fiber clamp.
3. Close the fiber clamp mechanism.
4. Push the cleaving wheel mechanism away from yourself to cleave the
fiber.
Note: Dust bin is removed for these photos.

5. Open the fiber clamp mechanism.
6. Make sure that the cut fiber end is safely in the dust bin.
7. Remove the adapter with the cleaved fiber from the cleaver.
8. Place the adapter with the cleaved fiber into the 915FS for splicing.
Note: There is no need to remove the cleaved fiber from the fiber adapter
after the cleaving operation.
Normal Use and Maintenance
Make sure that the rubber presser feet and the fiber guide groove are clean
(no dust and fiber debris). Keep the fiber contact surfaces clean by using
isopropyl alcohol with a lint free cleaning wand.
Change the position of the cleaving wheel if the cleaving quality degrades
due to the blade being worn (usually 1000 cleaves per blade position). After
the cleaving wheel has been rotated through all 16 positions, the height can
be increased and the wheel can be reused through all of the 16 positions
once again. The cleaving wheel can be rotated two times for a total of 48,000
cleaves.
Blade Position Change
1. Loosen blade locking screw.
2. Rotate blade to next scale position.
3. Hold side face of blade and lock screw at new position.
4. Lay 0.7 mm pencil lead across both pressure pads.

5. Move slider back and forth and check if blade touches pencil lead.
• If blade touches pencil lead: Perform a cleave and check cleave angle
on 915FS.
If cleave is not good: Check if blade is damaged or dirty at
new position.
• If blade drags pencil lead all the way across: Go to “Blade Height
Adjustment”.
• If blade does not touch pencil lead: Rotate pencil lead ≈180°
and try again.
If not sure: Perform a cleave and check cleave angle on 915FS.
If cleave is not good: Go to “Blade Height Adjustment”.
