• 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.
