Caution

When operating the handpiece always consider the safety of the patient.The handpiece is designed only for dental clinical use.

Check the vibration, noise and overheating outside the patient's oral cavity before use. If any abnormalities are found, stop using and contact your dealer.

If any abnormalities are found in use, stop using immediately and contact your dealer.

Do not allow any impact on the shank. Do not drop the handpiece.

Do not attempt to disassemble the handpiece nor tamper with the mechanism.Do not connect or disconnect the handpiece until the drive motor has

completely stopped.

Do not exceed a speed of 200,000min-1(rpm) at the head.Do not use eccentric, worn or damaged burs.

Use short shank bur for miniature head speed increasing handpiece. (Ti85L,

Ti85LA,Ti85) Using long burs could result in bur spin-out while using, or premature bearing failure.

Do not use a long surgical bur on speed increasing handpiece, which runs to 200,000min-1(rpm). Such long bur as 25mm in length shall not be used. Its shank may warp under load at a high speed and spin out of the handpiece when the load is released.

Before use always confirm that the bur is correctly seated and locked into place.

Depressing the push-button while handpiece bur is in rotation will result in

OVERHEATING of the handpiece head. Special caution must be exercised during use to keep cheek tissue AWAY from the push-button of the handpiece. Contact with cheek tissue may cause the push-button to depress and injury to the patient may occur.

Always operate with spray. Without cooling spray, the handpiece may build up heat.

Supply PANA SPRAY after each use.

Use only the genuine NSK-manufactured oil. (PANA SPRAY)
