For your safety and the safety of your patients
These instructions explain how to use your W&H product. However, we must also warn against possible hazardous
situations. Your safety, the safety of your team and, of course, the safety of your patients, are of paramount importance
to us.
It is therefore essential that you observe the safety notes on pages 14 – 15.
Intended use
The unit is a cleaning- and lubrication device for dental transmission instruments (especially straight- and contra angle handpieces,
turbines, airdriven scalers and airmotors).
Misuse may damage the Assistina unit and hence cause risks and hazards for users and third parties.
When transmission instruments are prepared with the Assistina unit, they are neither disinfected nor sterilized.
After cleaning and lubrication of the transmission instruments with the Assistina unit, they subsequently need to be
disinfected and sterilized.
