Check the end cap (Fig.6) is firmly tightened. If loosened, take the following actions.
NAC / BB / NBBW：Tighten the end cap with the provided cap wrench.
NM：Contact your dealer. (The cap wrench is not provided due to not being
able to change the cartridge.)
3) Insert the bur.
4) Rotate the handpiece for about one
minute at the Max. rotation speed stated

check for abnormalities such as
abnormal rotation, vibration, noise.
5) After the handpiece rotation has completely stopped, touch the
handpiece head to confirm the head is NOT heating abnormally (Fig. 3).
