> Make sure that the instrument used complies with the instrument group displayed.
> An overview for the correct power setting is included with each instrument.
> Ensure that the original shape of the instrument is not changed (e.g. by dropping).
> Instruments must not be bent back to shape or reground.
> Only insert the instrument when the handpiece is at rest.
> Never touch the instrument when vibrating.
> Remove the instrument from the handpiece after every treatment and place it in the instrument stand (provides

> The instruments Z25P and Z35P may only be operated with a coolant setting of max. 50%.
> Keep the handpiece moving at all times when operating the instrument.
