Caution
General Cautions:

• Do not use this for the treatment in dental surgery.
• NSK handpieces should not be rebuilt.
• Should the handpiece function abnormally, cease operation immediately
and return the handpiece to the dealer for repair.
Cautions on Operation:
• This handpiece is designed for (dental) treatment and precision technical
use. Longtime excavation with high torque with thick burs such as 4mm
or greater in diameter may cause a short life to the bur, hard-to-pull-off
bur or bur drop-off, which results in injury.
• Do not allow any impact on the shank. Do not drop the handpiece.
• Check the vibration, noise and overheating outside the patient's oral
cavity before use. If any abnormalities are found, stop using immediately
and contact your dealer.
• Make sure that the bur is securely locked in the chuck before each use.
Improper mounting of the bur could cause the bur to spin out during
rotation and endanger anyone in the vicinity.
• Be sure to check on the device and the components periodically.
• Make sure that the product is normal by rotating it with attention to
backlash, vibration, noise, heat generation, when you use it again after a
long time.
Caution
Do not connect or disconnect the handpiece until the motor has
completely stopped.
