5. Tighten the three set screws that hold the top blade assembly. Re-check alignment, and readjust if
necessary. Note: The bottom insert is held in place by the electrical contact pins and does not need to be
secured with the set screws.
6. Check the stripping performance to confirm that the fiber is being stripped cleanly and that splice
strengths are satisfactory. If one side is not stripping cleanly, shifting the top insert to tighten up the blade
offset on that side may help.
10.3.5 Inspect/Clean Cleave Blade
The diamond edge of the cleave blade should be regularly inspected for debris and/or damage that may result in
sub-optimum cleave performance. For easier inspection and cleaning, the cleave blade can be advanced forward
from its parked or "home" position. This can be achieved by sending the command:
MOTORTO(11 -1000)
from the command line (note the negative sign on the motor position). This will advance the cleave blade up
approximately 45°. Alternately, assign the macro "Service Cleave Blade.txt" to the user macro
Splice | User Macro Path 1... from the menu bar, and then execute by clicking on the User Macro icon.
The cleave blade should be cleaned using a cotton-tipped applicator wetted with acetone or isopropyl alcohol.
Wipe both sides of the blade starting away from the shank of the blade and wiping towards and over the diamond
edge, using very light pressure only. Never touch the edge of the blade with any hard or metal object. For very
loose debris, the cleave blade may also be cleaned by blowing clean (canned) air across the edge.
To reposition the cleave blade after inspection and cleaning, send the command:
MOTORTO (11 0)

Do not attempt to clean the diamond blade with your fingers or you will cut yourself.
