Manual cleaning and disinfection of the
contra-angled handpiece
– Remove the rotary instrument.
– Remove the contra-angle handpiece from the motor.
Pre-disinfection
If heavily soiled: Clean first with disinfectant cloths. Only use
disinfectants that have no protein-fixing effects. Clean and
disinfect the disassembled contra-angle
handpiece immediately after every treatment, to flush out any
liquid residues (such as blood, etc.) and to prevent settling on
the internal parts.
See page 39 on how to disassemble the handpiece.
Rinse under demineralised water (< 38 °C) with the aid of a
brush (not recommended in U.K.).
Then remove any liquid residues (absorbent cloth, blow dry
with compressed air).
Do not place the contra-angle handpiece in liquid
disinfectant or in an ultrasonic bath.
