The top insert, however, is held in place with setscrews. These two set screws are located in the back of the lid and
must be loosened before the top insert can be replaced.
6.3.2 Cleaning the Fiber Holding Block Insert
Debris in the fiber holding block v-grooves may interfere with fiber positioning. The v-grooves should therefore be
cleaned carefully, using a soft brush moistened with acetone
.
6.3.3 Adjusting the Transfer Insert Block
The block at the end of the transfer insert can be adjusted to accommodate fibers of slightly different diameter (see
Figure 41 for details). To do this, one must first loosen the two set screws in the back of the block. One then adjusts
the set screw in the bottom of the block. If going to a smaller diameter fiber, one turns the screw clockwise. If going
to a larger fiber, one turns the screw counterclockwise. The side of the block should remain flush with the end of
the insert. Once the correct block height has been reached, the two setscrews in the back of the block should be
re-tightened.
