chemicals, chlorine containing solutions or solvents such as benzine
or thinner. Do not use ultrasonic bath during the cleaning process.
1. Insert the bur. (Refer to “6. Inserting & Removing of Bur”)
2. Rotate the handpiece for about 20 seconds at the
Max. Rotation speed of the attached motor. During
rotation, check for abnormalities such as abnormal
rotation, vibration, noise.
3. After the handpiece rotation has completely stopped,
touch the handpiece head to confirm the head is not
heating abnormally(Fig.4).
Do a manual pre-cleaning, until the handpiece is visually clean. Submerge the
handpiece in a cleaning solution and flush the lumens with a water jet pistol with
cold tap water for at least 10 seconds. Clean the surfaces with a soft bristle brush.
9.2.2 Pre-cleaning
Use a washer-disinfector meeting the requirements of the ISO 15883 series.
Put the instrument into the machine on a tray. Connect the instrument with the WD
by using suitable adapter and start the program:
• 4 min pre-washing with cold water (<40°C);
• emptying
• 5 min washing with a mild alkaline cleaner at 55°C
• emptying
• 3 min neutralising with warm water (>40°C);
• emptying
• 5 min intermediate rinsing with warm water (>40°C)

The automated cleaning processes have been validated by using 0.5% neodisher
MediClean forte (Dr. Weigert).
Note: Acc. to EN ISO 17664 no manual reprocessing methods are required for these
devices. If a manual reprocessing method has to be used, please validate it prior to use.
9.2.3 Automated Cleaning:
Automated Thermal Disinfection in washer/disinfector under consideration of national
requirements in regards to A0 value (see EN 15883). A disinfection cycle of 5 min
disinfection at 93°C has been validated for this device to achieve an A0 value of 3000.
9.2.4 Disinfection:
Drying of outside of instrument through drying cycle of washer/disinfector. If needed,
additional manual drying can be performed through lint free towel. Insufflate cavities
of instruments by using sterile compressed air.
