•Only Use Tips that NSK has approved for VarioSurg use. Damage, failure or an accident may occur; the following are
possible failure modes (NSK Warranty Exclusions).
• Vibration failure caused by using non conforming screws (Incorrect Tip).
• Patients' accidental ingestion of Broken or damaged Tip.
• Damage to thread of Handpiece output shaft.
• Handpiece, Handpiece Cord, Tips, Tip Wrench, and Tips Holder are all non-sterile items. Be sure to sterilize them
before use.
• Never sterilize the Handpiece etc., using ultraviolet sterilization. It may cause discoloring.
•After autoclave sterilization, wipe away any remaining water drops. They may cause discoloring.
•Do not press the Tip against anything unless it is part of treatment. Ultrasonic vibrations may damage tooth surface.
•The Tip wears down after every use. After wearing down, vibrations become weak and coating may come off. If these
problems occur, be sure to replace the Tip with a new one. It is recommended that the Tip be changed after 5 uses.
•When replacing the Tip, use the Tip Wrench to ensure that the new Tip is securely mounted to the Handpiece. If
mounting is loose, vibrations may be weak and output inadequate.
•If a new Tip is mounted with stray objects on the screw, vibrations may be weak and output inadequate. If there is
anything on the Tip, clean it off before mounting to Handpiece.
•If it feels as though the Tip is not vibrating during use, remove the Handpiece from the mouth of the patient, and step
on the foot control again. If the situation is no better, the Tip may have become loose during use, so check to make
sure it is securely mounted.
