6. Closure or Terminal Preparation

6.1 Prepare the closure or terminal according to the instructions supplied with it.

IMPORTANT: Be sure to read, understand andfllkrw the steps ofthis section

before using the tool.

the blade depths are set too deep, damn:ge to the fibers mn:y result.

Failure to carefully fllluw these procedures

may

result in fiber or ribbon damn:ge, which

in tum mn:y lead to loss ofservice.

7. Accessing a Tube

7.1 After preparing and opening the tool as described in Section 5:

a) Determine the start point and direction in which you will make the cut.

Position the tool over the central tube so that the middle of the tool is aligned

with the start location of the cut and the top and bottom arrows are pointing in

the direction of the cut (Figure 9).

Hold the tool in your left hand. Tilt it backward, lifting the front and pressing

down on the rear of the tool. Apply enough force to compress the front lower

and the rear upper ''V''-shaped spring loaded guides. While holding this position

(Figure 9, inset) use your right hand to tighten the knurled knob, closing the tool

on the tube. TIghten until just snug.

Turn the handle slightly to see if the tool will track on the tube. Tighten the tool

in small steps until the tool moves smoothly along the tube. The purpose of this

method of placing the tool on the tube is to prevent blade damage from side

forces on the blades while they become engaged with the tube.

NOTE: Centering ofthe tool on the cabk is very important. The conical shape ofthe

rollers will "self center" the tube in the tool after a short distance

(1-2

inches), but care·

should be taken to center the tube when performing the positioning procedure. The tool is

designed to straighten the tube as

passes

under

the cutting blades; huwever, it is limited in

this respect and larger buffer tubes

may

notfolly straighten. This results in one blade cut

ting deeper than the other. See Figure 10for the recommended position ofthe tool relative

to tube curvature.

Let the tool ride on

ofany curvature'

the thumbscrew is too tight it mn:y cause the tool to bind characterized by excessive force

required to tum the drive handle and the tool slipping on the central tube.

the thumb

screw is too loose the handle will spin easily and the tool will slip on the tube.

in doubt

leave the screw slightly loose as it can easily be tightened in the fllluwing steps.

Final blade depth adjustment:

7.2 It is recommended to adjust the blades to maximize the score depth without

penetrating the tube (Figure 11). This

step

critical to protect the fibers inside the

tube.
