5. Checking the Handpiece Before Each Use
The SGS/SGA series handpieces are designed for use with surgical burs (ø2.35mm, approx.
70mm in shank length).
Follow the check below before use. If any abnormalities are found, stop using the handpiece
immediately and contact your Authorized NSK Dealer.
1) Mount the Bur. (Refer to “3. Mounting and Removing the Bur”)
2) Adjust the handpiece rotation speed in accordance with the allowable maximum speed
for the attached bur.
3) Rotate the handpiece and check for abnormal rotation, vibration, noise and overheating.
If any of these conditions are found, stop using the handpiece and
contact your
Authorized NSK Dealer.
4) If there are no immediate apparent abnormalities, continue to rotate the handpiece for
about 1 minute. Then stop rotation and check for abnormal heating on the outer
surface. If abnormal heating is detected, stop using the handpiece and
contact your
Authorized NSK Dealer.
5) Operate the handpiece if no abnormalities are observed.
To Mount the Stopper (ONLY for SGS-ES, SGA-ES)
When using a bur designed for dental straight handpieces in implant surgery, etc., attach
the Stopper (Option) to the handpiece.
1) Remove the bur from the handpiece. (Refer to “3. Mounting and Removing the Bur”)
2) Turn the Bur Lock Ring to the OPEN position. (Fig. 2)
3) Insert the threaded portion of the Stopper into the chuck then screw it in with the
provided screwdriver.

Immediately after a surgery, the handpiece should be cleaned, lubricated and
sterilized. Failure to properly maintain the handpiece can lead to contaminants
remaining inside the handpiece. Unremoved blood may result in product failure
due to the internal blood coagulation. Improper maintenance may also lead to
overheating, causing burn injuries, product failure, or difficulty in attaching and
detaching the bur.
8. Periodical Maintenance Checks
CAUTION
The handpieces stated below are not suitable for the stopper. Use only with a surgical bur.
