Cutting Fiber

Insert a fiber into the Fiber Cutter and determine the length of the

fiber to be cut.

Press down the Fiber Cutter in a single stroke to cut the fiber.

When the fiber is cut, an insertion mark is inscribed on the fiber.

For a 2.2-mm dia. standard fiber only.

Insertion mark

2.2-dia.

Insert a fiber into the Fiber Cutter in the direction indicated by the

arrow (refer to the following figure).

The cutting holes cannot be used twice. If the same hole is used

twice, the cutting face of the fiber will be rough and the sensing dis-

tance will be reduced. Always use an unused hole.

Use either one of the two holes on the right (refer to the following

figure) to cut a thin fiber as follows:

1. An attachment is temporarily fitted to a thin fiber before

shipment.

2. Secure the attachment after adjusting the position of it

in the direction indicated by the arrow.

3. Insert the fiber into the E39-F4 to cut.

Note:

Insert the fiber in the direction indicated by the arrow.

Connection

Do not pull or press the Fiber Units. The Fiber Units have a with-

stand force of 1 kg or 3 kg (pay utmost attention because the fibers

are thin).

Do not bend the Fiber Units beyond the permissible bending radius.

Do not bend the edge of the Fiber Units.

The Fiber Head could be broken by excessive vibration. To prevent

this, the following is effective:
