7. Checking the Handpiece Before Each Use
Follow the check below before use. If any abnormalities are found, stop using the handpiece immediately
and contact your Authorized NSK Dealer.

3) Mount the bur. (Refer to "5. Mounting and Removing the Bur")
4) Rotate the handpiece for about one minute with coolant water at the Max. rotation speed of the attached

NOT heating abnormally (Fig. 5).
