Cleaning the handpiece optics
CAUTION
From time to time the cleaning of the handpiece optics can be
required because of soiled optics, for example due to a missing optic
protection cap. Therefore, the handpiece optics should be cleaned
after every 20 usages of the device.
Please proceed as follows for cleaning the optics at the handpiece:
1.
Switch off the control unit and unplug the handpiece from the
control unit.
WARNING
Never inspect or clean the handpiece optics when the laser system is
switched on.
2.
Dismount the optical fiber/ glass rod/ optic protection cap from the
handpiece optics.
3.
Dismount the handpiece sleeve from the handpiece body.
4.
Use a commercially available lint-free cleaning swab (for example
for cleaning camera or CD player lenses) or the official
Dentsply Sirona cleaning sticks (Order No.: 62 37 098 [Pack of 50])
and moisten it with a little bit of isopropanol.
