Blade Adjustment and Replacement
5.6
If your cleaver stops making acceptable cuts, try increasing
the fiber tension by using the switch on the back of the cleaver.
The switch rotates in a clockwise direction from "Standard" (5
oz) to “+ 0,4 N" (6.4 oz.) (Figure 9).
Figure 9
Use a step-up, trial and error procedure when increasing the fiber
tension. For example, use the small slotted screwdriver to turn
the switch form its “Standard” 9 o’clock position until its mark is
at a 10 o’clock position. Use the cleaver and make a splice. If no
improvement is noted, turn the switch to the 11 o’clock position,
make a splice etc., until optimum setting is found.

Corning Cable Systems recommends factory service for
blade replacement and adjustment. The following procedure is
provided should it be necessary to replace the cutting blade in the
field.
5.8
Remove the slotted screwdriver and blade replacement tool
from the cleaver case. Use a cotton-tipped swab to position the
blade arm as shown in Figure 10. Position the tool on the blade.
Figure 10
5.9
Release the cutting blade retaining screw with the slotted
screwdriver and withdraw the blade from the cleaver.
Take care not
to misplace the screw.
5.10
Place the new cutting blade into the tool (Figure 11).
Figure 11
5.11
Insert the retaining screw into the hole of the replacement
blade.
5.12
Position the replacement blade in the cleaver, lining up
the screw with the threaded hole. During positioning, use the
tool to press the replacement blade upwards and back against the
stop pin (Figure 12 inset).
5.13
Tighten the retaining screw with the slotted screwdriver
(Figure 12). Remove the swab from the blade arm.
Figure 12
5.14
Make trial cuts after replacing the blade to make sure
the cleaver is working properly. If the blade pushes the fiber out
of position, the front edge of the blade is positioned too low.
Loosen the screw and repeat steps 5.12 and 5.13.
