CAUTION
Always follow the instructions provided by the bur manufacturer.
When a bur is rotating, do not turn the bur lock ring in the direction. Doing so will cause the Handpiece to break.
Particularly when replacing a bur, do so after rotation has completely stopped.
Should the handpiece function abnormally during use, stop using the handpiece immediately and contact your Authorized NSK
Dealer.
Clean the Handpiece on a timely basis. Follow the procedure in "7. Post-use Maintenance" in the Operation Manual to perform
cleaning.
Do not use the following fluids to wipe, immerse or clean the product; strong / super acid water, strong acid / alkaline
chemicals, chlorine-containing solutions, solvents such as benzine or thinner.
Do not lubricate the Motor Handpiece with oil. Doing so might cause it to generate heat or malfunction.
Perform regular function and maintenance checks. (Refer to "8. Periodical Maintenance Checks")
If the handpiece has not been used for a long period, rotate the handpiece and check for noise, vibration and overheating
before use.
To avoid clinical downtime it is recommended that a spare be kept on hand in case of a breakdown during treatment.
