and tip with water at a low power level for around 20- 30 seconds by pressing down
the foot pedal.
• In case of damage, excessive wear at least once a year: replace the watertight O-ring
which is located in the rear part by using the fitting tool (for details see Fig. 6).

to prolong its efficacy and prevent
internal leaks.

6 .2 . tIP MAIntEnAncE

Basically, shape and mass of a tip are the determining factors to obtain consistent
performance of the ultrasonic generator.
• The thinner the diameter of a tip, the less the tip should be re-used.
• After a certain time of usage the shape of a tip will gradually be modified, i.e. the tip
will become shorter.
• Operation with a worn tip will lead to longer preparation time and may increase
temperature in the cavity or root canal. It may also lead to tip breakage.
1. Do not actively modify a tip by filing.
2. Regularly check a tip for visible wear with a loup or microscope.
3. Replace
– the tip which is 3 to 4mm short after several operations, compared to the length
of a new tip.
– the tip which has apparently suffered an accidental impact (fall etc.).
– the diamond coated tip as soon as it is worn.
– tips that are bent to match canal curvature cannot be reused.
– follow the use instructions received with authorized replacement tips.

1. Regularly inspect accessories and cords for insulation defects and replace if necessary.
2. Regularly check whether the air vents of the control unit are clean to avoid overheating.
