Rotary instruments
– Use only rotary instruments that are in perfect
condition and be careful when the rotary
instrument is rotating.
– Insert rotary instruments only when the contra-
angle handpiece is stationary.
– Do not activate the press-button of the contra
angle handpiece during operation. This leads to
detachment of the rotary instrument and makes
the head of the contra-angle handpiece hot.
To change rotary instrument in the Osscora contra-angle
handpiece:
Insert the instrument into the contra-angle handpiece
until back stop (a). Activate press-button (b) and turn the
instrument until it engages (c).
Check secure location by applying slight axial tension.
Remove the instrument by pushing the press-button.
