If your treatment center is equipped with the ApexLocator option, you can
determine that the burr drive stops automatically at the physiological
apex, see “Turning on/off the automatic motor stop of the
ApexLocator" [ → 119]. If the Auto-Reverse function is switched on, the
next time the foot switch is activated following a motor stop, the motor is
switched to counterclockwise rotation. When the file is withdrawn, the
burr drive automatically switches back to clockwise rotation.
➢ Touch the
AutoRev

If the key is marked orange, the Auto Reverse function is
activated.
IMPORTANT
Torque adjustment
The maximum adjustable torque depends on the system motor and the
speed settings.
CAUTION
Improperly selected speeds and torque values endanger the patient.
Treatment errors, e.g. breaking of a file, may result from incorrect
settings.
➢ Observe the manufacturer's instructions regarding file systems.
CAUTION
Only the Sirona ENDO 6:1 contra-angle handpiece may be used for the
endodontics function.
Instruments from other manufacturers can lead to malfunctions. Outside
instruments may be improperly calibrated for endodontics.
➢ Use only the ENDO 6:1 contra-angle handpiece from Sirona for
endodontics.
➢ Check whether the reduction ratio on the touchscreen agrees with
the value specified on the contra-angle handpiece being used.
