Maintenance of Splicing Quality
2-2. Rotating Cleaver Blade
If the cleaver does not cleave properly, rotate the blade 1/16th of a turn to replace the
worn out blade position with a sharp blade position. To rotate blade, do the following:
(1) Remove the blade cover.
(2) Using a small slotted screwdriver, loosen the blade lock screw.
(3) Rotate the circular blade 1/16th of a turn.
(4) Tighten the blade lock screw.
(5) Attach the blade cover.
Blade Height Adjustment
After the circular blade has been rotated a complete revolution (16 positions), blade
height needs to be adjusted to compensate for blade wear. Do the following:
(1) Loosen the blade lock screw.
(2) Using a .89mm hex wrench, loosen the adjuster lock screw.
(3) Using a 1.5mm hex wrench, turn the adjuster clockwise so that the reference dot
aligns with the next position mark. Never attempt to rotate the adjuster more than 2
position marks.
(4) Tighten the adjuster lock screw.
(5) Tighten the blade lock screw.
Blade Replacement
After the circular blade is raised 3 times, it needs to be replaced. Contact your Fujikura
splicer distributor.
• When rotating the blade, do not touch the cutting edge. Move the blade
with a thin cotton swab, for easy and safe rotation.
• After blade height adjustment, the 16 blade positions can be used again. If
the cleaver does not cleave properly, rotate the blade.
