1.0 Safety and Helpful Hints
Use reagent-grade isopropyl alcohol that is 99% pure to clean the fibers and other components. When
terminating connectors on any cable containing grease, ensure that all grease is wiped away and the buffer, coating and fiber are thoroughly cleaned with isopropyl alcohol.
Isopropyl alcohol is not shipped with the 3M™ Field Termination Kits; however, a bottle for the alcohol is
included.
Note: Carefully follow safety, health and environmental information given on the container label or the Material Safety Data Sheet for the isopropyl alcohol.
CAUTION Do not touch any part of the heating block of the Hot Melt oven during operation.
It is very HOT.
WARNING
• Safety glasses should be worn when working around optical fibers.
• Do not view fiber ends if they are illuminated with a laser.
• Keep oven clear from flammable material.
• Disconnect power supply when cleaning.
Hot Melt Oven Safety Information
This Hot Melt Connector Oven is intended for melting Hot Melt adhesive in Hot Melt Connectors. It has
been designed and tested for use only with the 3M™ Fiber Optic Connectors System. Other uses of this product may lead to poor performance or an unsafe condition.
WARNING
1. Power cord must be grounded and plugged into a grounded outlet.
2. Eye hazard. Do not view fiber ends if they are laser illuminated as eye
damage may result. Illuminate fiber ends with white light only.

4.4 Insert the connector into the hot melt connector holder.
4.5 Place the load adapter, with slot aligned with handle, into an available port in the oven.
IMPORTANT: Do not place connector in a hot load adapter. This may cause adhesive to flow to the outside of the ferrule. Load adapter should be at room temperature when connector is inserted.
4.6 The 3M™ LC Hot Melt Connector should be in the oven for at least 75 seconds. The connector should not be in the oven longer than 5 minutes.
4.7 Place the heat shrink fixture in an available port in the oven.
Note: This step is only necessary for use with the
1.6–2.0 mm jacketed LC hot melt connector.

9.0 Stripping Procedure for 900 micron Fiber
9.1 Place the cable on the strip template. Mark buffer at 11 mm. Using the 3M™ Stripping Tool 6365-ST, remove the buffer in small increments until 11 mm of buffer has been removed.
9.2 Using a lint-free cloth moistened with isopropyl alcohol, clean the bare fiber to remove any oils or acrylate coating debris.
9.3 Check the final strip length and adjust if necessary.
10.0 Stripping Procedure for 1.6 – 2.0 mm Jacketed Fiber
10.1 Place the jacketed fiber on the strip template and use a fiber marking pen to mark the location of the jacket cut. Using the 3M™ Stripping Tool 6365-ST, remove 33 mm (1 1/3") of jacket off cable.
