11.3.1. Inspect/Clean Cleave Inserts
The cleave vacuum V-grooves, as well as the cleave top insert clamping surfaces, should be inspected regularly
for dirt, debris and/or damage. Damage or dirt on these surfaces could cause the fiber to break at the insert when
cleave tension is applied. The V-grooves and top insert can be cleaned with the soft brush provided in the tool kit.
Wet the bristles of the brush with acetone for more thorough cleaning.
Note: Do not clean the cleave V-groove inserts while vacuum is on. Wear safety glasses and be very careful
when “brushing” with acetone, as acetone may “spray” from the brush.
If the vacuum ports at the bottom of the V-groove appear plugged, and/or the top or bottom inserts appear
damaged, it may be necessary to remove them for more thorough cleaning and/or replacement.
11.3.2. Change/Remove Cleave Inserts
The cleave assembly contains replaceable V-groove inserts which are designed to hold a specific fiber size. To
change an insert, loosen the two appropriate 2-56 set screws in the base of the cleave block using a 0.035” hex
key (one full turn counter-clockwise should be sufficient). Slide the insert sideways to remove. Install the new
insert such that the V-groove side is up and the size label (if imprinted) is right side up. Make sure the new V-
groove is fully seated and that the ends are flush side-to-side with the base block. Gently tighten the two set
screws to secure in place.
The top cleave inserts can be similarly changed by loosening the two appropriate top set screws, which are
accessible from the front edge of the top. Top cleave inserts can be flipped “upside down” for a “new” clamping
surface.

11.3.3. Inspect/Clean TMS Inserts
Although the top and bottom TMS (Thermo-Mechanical-Stripper) inserts are cleaned after every strip, they still
should be inspected periodically for build-up of dirt and debris and/or damage to the stripper blades. For a
