Rotary Instruments
•
Use only rotary instruments which are in perfect condition and which have shanks
that meet the requirements of the DIN EN ISO 1797-1 standard. Follow the operating
instructions of the manufacturer.
•
Insert rotary instruments only when the contra-angle handpiece is stationary.
•
Do not interfere with the running or slowing down of rotary instruments.
•
Do not active the rotary chuck of the handpiece or press button of the contra-angle during
operation or slowing down. This leads to detachment of the rotary instruments, damage
to the rotary chuck(handpiece), and/or makes the press button hot (contra-angle) (risk of
injury).
