Mounting the optical fiber:
1. Open handpiece by pressing both snap tabs and pull apart the
handpiece sleeve from the handpiece body.
2. Remove the protection screw from handpiece body by using the
transport and sterilization tube.
3. Remove the protective cap from the optical fiber.
4. Insert the optical fiber into the handpiece and screw it on. Tighten
the optical fiber only slightly so that it can be loosened with the
transport and sterilization tube again with ease. Make sure not to
overwind the transport and sterilization tube!
5. Remove the transport and sterilization tube from the optical fiber
prior to mounting the handpiece sleeve on the handpiece body.
6. Attach a single-use tip on the handpiece sleeve.
CAUTION
Check whether the single-use tip is damaged before attaching it.
Replace it if necessary.
Please check that the single-use tip is firmly attached prior to each
use.
7. Insert the handpiece body back into the handpiece sleeve making
sure that the optical fiber slides easily through the single-use tip.
Also check if the snap tabs have clicked into their rests.
8. Trim the end of the optical fiber with the fibercutter until the light of
the aiming beam projects an uniform circular pattern, see chapter
„Adjusting the optical fiber with the fiber cutter" [→ 30]. To do this,
aim the optical fiber vertically at a white background located approx.
5 cm away. If the probe projects no pattern at all or only an uneven
pattern, cut off one to two millimeters. Always make the notch
perpendicular to the optical fiber.
WARNING
If the optical fiber does not protrude at least 1 cm out of the single-use
tip, there is a risk that the single-use tip will heat up.
4.4.2.3.4 Adjusting the optical fiber with the fiber cutter
1. Place the optical fiber in the fiber cutter at the notched mark.
2. Press the fiber cutter together.
3. Bend the optical fiber at the notched location.
Ä The optical fiber breaks at the notched location with a smooth,
perpendicular fracture surface.
Check to see if the light of the aiming beam projects a uniform circular
pattern. To do this, aim the optical fiber vertically at a white background
located approx. 5 cm away. If the probe projects no pattern at all or only
an uneven pattern, cut off another one to two millimeters.
NOTE
Press firmly but do not squeeze the optical fiber. You just need a little
3 .
notch to receive a perfect result when breaking the fiber at the notch.
