Handpiece Maintenance

Hygiene and Maintenance

Follow your local and national laws, directives, standards and guidelines for cleaning, disinfection, and sterilization

  • Clean the handpiece immediately after every treatment, to flush out liquid (e.g., blood, saliva etc.) and to prevent settling on the internal parts.
  • Operate the handpiece for at least 10 seconds at idle speed.
  • Ensure that all coolant outlets are rinsed out.
  • Wipe the entire surface of the medical device with disinfectant.
  • Do not place the handpiece in liquid disinfectant or in an ultrasonic bath.

  • Clean the handpiece under running tap water (< 35°C/< 95°F).

  • Move moving parts back and forth several times.
  • Remove liquid residues using compressed air. Use only oil-free, filtered compressed air with a maximum operating pressure of 3 bar for manual drying.
  • Lubricate the dry handpiece immediately after cleaning and/or disinfection.
  • Test the handpiece after lubrication by operating the handpiece so that excess oil can escape.
  • Proceed with sterilization.
