WARNING
• Clean, disinfect, lubricate and sterilize the handpiece immediately (within 1 hour) after each treatment to remove residue. Failure to properly maintain
the handpiece may cause infection, product failure, overheating leading to burn injuries. (Refer to "9. Post-use Maintenance")
• Do not change or otherwise reinsert a bur into the handpiece during a procedure. Doing so can introduce blood or other debris into the chuck,
increasing the risk of cross-contamination.
• Do not rotate the motor when the Bur Lock Ring is at the OPEN position, or when a bur is not mounted in the chuck. Either situation It may cause burn
injuries due to sudden heat generation. In addition, the motor insert could be damaged which may lead to difficulty in connecting and disconnecting the
handpiece.
• Always keep the bur shank clean. Dirt or debris in the chuck could cause heating, poor bur concentricity, or low chuck retention force.
• Supply coolant water through the irrigation nozzle while using the handpiece. Other irrigation methods than recommended may lead to overheating
causing burn injuries.
• Do not apply excess pressure to the bur as it may break, bend or become difficult to remove. Doing so may also cause burn injury due to abnormal
heating.
• Ball bearings are wear items and may require replacement. Be sure to inspect the handpiece before use (Refer to "8. Checking the Handpiece Before
Each Use"). If abnormal vibration or noise are found, the bearings or other internal parts may be worn out or damaged. Damaged parts may lead to
handpiece overheating causing burn injuries. If overheating is suspected, stop using the handpiece immediately and contact your Authorized NSK
Dealer.
• The temperature at the tip of the handpiece may reach up to 51˚C depending on the environment.
Contact with the body surface of the patient or the operator must be within 1 min..
Contact for longer than the specified time could cause higher risk of low temperature burn injury.
