4. Operation
Assembly/removal
Do not assemble/remove during
operation!
➊ Insert the air motor with RM connection into the
apertures of the turbine hose.
➋ Firmly screw the union nut on in a clockwise
direction.
➌ Set the speed regulation ring to F or R.
➍ Check the leak-tightness of the air motor with RM
connection.
➎ Unscrew the union nut anticlockwise from the
supply hose.
9
➊ Push the handpiece/contra-angle onto the motor
until it engages audibly ➋.
➌ Check the connection to the motor is secure.
➍ Remove the handpiece/contra-angle using axial
tension.
10
Rotary instruments
> Use only rotary instruments which are in perfect condition. Observe the manufacturer’s recommendations.
> Insert the rotary instrument only when the handpiece/contra-angle is stationary.
> Never touch rotary instruments which are still rotating.
> Do not activate the chuck lever of the handpiece or the latch of the contra-angle handpiece during operation
or slowing down. This leads to detachment of the rotary instrument and damages the chuck lever/latch.
11
RC-43
➊ Open the chuck lever.
➋ Insert the rotary instrument up to the back stop.
➌ Close the chuck lever.
➍ Check that the rotary instrument is held securely
by applying axial tension.
➎ Open the chuck lever and remove the rotary
instrument ➏.
12
RC-58

> Follow your country-specific directives, standards and guidelines for cleaning, disinfection and
sterilization.
> Wear protective clothing.
> Remove the rotary instrument.
> Remove the air motor from the supply hose and the handpiece/contra-angle from the air motor.
> Clean and disinfect the air motor, handpiece/contra-angle immediately after every treatment, to rinse out
any liquids that may have entered (e.g. blood, saliva, etc.) and prevent seizing up of the internal parts.
> Sterilize the air motor, the handpiece/contra-angle following manual cleaning, disinfection and lubrication.
> Sterilize the nozzle cleaner following cleaning and disinfection.
15
Pre-disinfection
> If heavily soiled, clean first with disinfectant
cloths.
Only use disinfectants that
have no protein-fixing effects.
Manual cleaning internal and external
➊ Rinse under demineralised water (< 38°C) with the
aid of a brush (not recommended in UK).

* When using longer rotary instruments (or if the rotary instrument is not inserted up to the back stop), the user must ensure, by correct selection of the operating conditions, that there is no
danger to the user, patient or third parties.
** If the rotary instrument is not inserted up to the back stop, the minimum chuck length must be maintained. In this case, or when using rotary instruments longer than 50 mm, the user must
ensure, by correct selection of the operating conditions, that there is no danger to the user, patients or third parties.
