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).

CAUTION: Use a properly sized screwdriver to adjust the

switch. Over- or under-sizing the tool may result in the destruction

of the switch.

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.

5.7 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.

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).

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.

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.
