This guide provides instructions for an experienced installer to properly cleave optical glass fibers using the
Extron Fiber Optic Cleaver. The cleaver can cut single fiber, 125 µm diameter strands to any length from 6 mm to 20 mm.
WARNING: • Serious injury can result from improper use of the cleaver.
• Safety glasses should be worn during fiber preparation and splicing operation. Fiber
fragments can be extremely dangerous if they come into contact with your eyes or skin.
• The cleaver blade is extremely sharp. Personal injury can result from contact with the blade.

Cleave a Fiber Strand
To Cleave a Fiber Strand:
1. Prepare the fiber cable. Refer to the fiber stripping instructions in the
Fiber Optic Termination Kit User Guide.
2. Clean the exposed fiber.
3. Push the slide button, (
WARNING: Do not leave a finger in the driving area of the slide
button, (c), when cleaving. Personal injury could result.
4. Insert the bare fiber into the open scrap collecter and lay it across the two
clamp pads. Set the buffer in the groove on the fiber plate, (g), and fix it in
place by lowering the fiber holder, (h).
5. Slide the cable to align the end of the buffer with the 10.5 mm mark on the
graduated scale of the cleave gauge, (e). The
buffer will be very close to touching the clamp

Maintenance and Adjustments
The following section describes three maintenance operations; blade and pad cleaning, blade position, and blade height
adjustment, that must be performed regularly to ensure optimum operation of the cleaver.
Cleaning the Cleaver
For proper operation of the cleaver, the blade and clamp pads must be
cleaned frequently.
To clean the blade and pads:
1. Remove the blade cover, (
2. Clean the visible portion of the circular blade, (
clamp pads, (i), with cotton swabs soaked with a few drops of the
included cleaner.
3. Allow to air dry for several minutes, then replace the blade cover.
Blade Position Adjustment
The cleaver uses a circular blade with 16 cleaving positions. If the cleaver does not cut properly, or does not cut the fiber
cleanly on the first attempt, rotate the blade 1/16th of a turn to the next cleaving position to replace the worn portion of
blade with a sharp blade.
To rotate the blade:
1. Remove the blade cover, (
), see “Blade Position Adjustment” below.

When the circular blade has been rotated one complete revolution (16 positions), its height requires adjustment to
compensate for wear.

Blade Replacement
After the circular blade has been raised three times it must be replaced. Contact Extron for ordering details.
Fiber Scrap Collector Mechanism Installation and Removal
The fiber scrap collector mechanism, (o), must be installed before using the cleaver and removed for most maintenance
procedures.
Remove the side cover before installing the mechanism, see “Side
Cover Removal” on page 4.
To Install the Scrap Collector Mechanism:
1. Insert the gear of the scrap collector mechanism, (
cleaver, then slide it until the screw holes align with the holes of
the cleaver.
2. Install two M2x6 screws (included) as shown.
