1. Use correct eye, face and personal protection to avoid possible infection.
2. Disconnect handpiece from air motor.
3. Remove air motor from air supply hose.
10.1 Preparation
Disconnect the air motor from the tube. Remove gross soiling of the instrument with
cold water (<40°C) immediately after use. Don’t use a fixating detergent or hot water
(>40°C) as this can cause the fixation of residuals which may influence the result of
the reprocessing process. Store the instruments in a humid surrounding.
Safe storage and transportation to the reprocessing area to avoid any damage and
contamination to the environment.
10.2 Cleaning
10.2.1 Preparation at the Point of Use:
Do a manual pre-cleaning, until the air motor is visually clean. Submerge the air
motor 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.
10.2.2 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)
• Emptying
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.
10.2.3 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.
10.2.4 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.
10.2.5 Drying:
CAUTION: Visual inspection for cleanliness of the air motor. If necessary, p
erform reprocessing process again until the air motor is visibly clean. Before
packaging and autoclaving, make sure that the air motor has been maintained
acc. to this instruction.

Air motor should be sterilized after each and every treatment.
1. Air motor should be lubricated as per user manual.
2. Insert the air motor into an autoclave pouch and seal pouch correctly. The
autoclave pouch should comply with the requirements of EN ISO 11607.
3. Sterilize at 134 °C for 5 mins. Sterilization of instruments by applying a fractionated
pre-vacuum steam sterilization process (according to EN 285/EN 13060/EN ISO
17665) under consideration of the respective country requirements. Flash
sterilization is not allowed on lumen instruments!
4. Air motor should be stored in a sealed pouch in a dry, clean and dust free place
out of direct sunlight until required for use.
10.5 Sterilization
10.4 Oil Lubrication
1. Apply 1-2 drops of high quality lubricant oil intended for use with dental
handpiece / air motor (not included with device) into drive air tube (Fig. 1)
2.
Connect air motor to air supply hose. Operate the motor for approximately 10 seconds.
