Rotary instruments
> Only use rotary instruments which are in perfect condition and which have shanks that meet the
requirements of the DIN EN ISO 1797 standard. Observe the manufacturer's recommendations.
> Insert the rotary instrument only when the technical handpiece is stationary.
> Never touch rotary instruments which are still rotating.
> Do not activate the twist chuck on the technical handpiece during operation or slowing down. This leads to
detachment of the rotary instrument and damage to the twist chuck (risk of injury).
