The fiber optic core cutter has a locking screw to protect the cutter wheel when in transit or not in use. A hexagonal key is supplied in the MOST repair kit to release the locking screw.

NOTE: Tighten the transportation locking screw after use.

Fiber Optic Core Cutter Remaining Cut Indicator

The fiber optic core cutter can be used for approximately 1260 cuts. The indicator line on the remaining cut indicator window only becomes visible when the fiber optic core cutter has 150 cuts or below available.

NOTE: When the fiber optic core cutter has reached the maximum allowed cuts, the cutter will become locked and the fiber optic conductor stripper must then be renewed.

Before using the fiber optic conductor core cutter, make sure it has enough cuts remaining to complete the repair process by viewing the remaining cut indicator.

Fiber Optic Conductor Contact Crimping Pliers

A small amount of effort is required to operate the fiber optic conductor contact crimping pliers and secure a fiber optic conductor contact to the fiber optic conductor core.

The new fiber optic conductor contact is placed into the cramping mechanism in the head of the pliers. The locking arm is repositioned to hold the conductor contact securely in position. The locking arm must locate on to the retaining pin.

The prepared end of the fiber optic core is then inserted into the new conductor contact.

The fiber optic core and conductor contact must be pushed and held against the spring pressure in the cramping mechanism. The grips of the fiber optic conductor contact crimping pliers are then be closed, cramping the conductor contact to the conductor core.

NOTE:
  1. Only use the approved fiber optic conductor contact crimping pliers to cramp a new conductor contact.
  2. A conductor contact must only be cramped when using the fiber optic conductor contact crimping pliers.

The cramping mechanism inside the head applies the appropriate pressure to the conductor contact at 4 points. This makes a secure contact and does not damage the conductor core.

When the new conductor contact has been cramped to the fiber optic core do the following. Make sure the fiber optic core end sits 0.01 mm (0.00039 inch) to 0.1 mm (0.0039 inch) below the height of the conductor contact end.

NOTE: Make sure the fiber optic conductor lead contact remains clean and protected at all times. Install a fiber optic conductor contact protective cap.
