WARNING
• Immediately after a treatment (within 1 hour), perform maintenance and then store the handpiece. Failure to
properly maintain the handpiece may lead to overheating, causing infection, burn injuries or product failure.
(Refer to "7. Post-use Maintenance")
• If blood infiltrates inside a handpiece, an automatic handpiece cleaning and lubrication system may not
totally clean the internal handpiece components and may lead to blood coagulation inside the handpiece.
Coagulated blood may cause handpiece failure and overheating, causing burn injuries. To avoid the risk, NSK
recommends to immediately lubricate those handpieces with PANA SPRAY Plus.
• Depressing the Push Button while the handpiece is in rotation may lead to overheating, causing burn injuries
or product failure. Avoid the push button to contact with any oral tissue.
• Keep any debris or other foreign materials away from inside the gear or the handpiece. Foreign materials
remaining inside may lead to overheating, causing burn injuries or other accidents.
• Ball bearings, in time, will become worn and will require replacement. Be sure to inspect the handpiece
before use (Refer to "6. Checking the Handpiece Before Each Use"). If abnormal vibration or noise are
found, the bearings or other internal parts may require replacement. 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.
