Step 3

Insert the cleaning tool into the first adapter slot. Align the key on the cleaning tool with the matching

notch in the adapter slot. The cleaning tool works properly only when the cleaning head is properly

inserted.

Step 4 Advance the thumb wheel until you hear two hard clicks. This advancement ensures that enough lint-free

cleaning cloth advances across the face of the fibers in the ferrule.

Note The thumb wheel makes a series of soft clicks followed by a "hard click" when turned. The hard click

is represented by six large notches along the edge of the thumb wheel. Always advance the thumb wheel

until you hear two hard clicks.

Step 5 Clean the two visible ferrules and then rotate the array adapter 180 degrees to clean the remaining two

ferrules.

Step 6 Repeat these steps for all S2 HBMT connectors that require cleaning.
