10. Periodical Maintenance Checks
Every 3 months perform periodical maintenance checks,
referring to the check sheet below. If any abnormalities are
found, contact your Authorized NSK Dealer.
Points to check Details
Head Cap or Cap
(FX22) is loose
Tighten firmly using the correct head cap
wrench or cap wrench.
Rotation
Rotate the handpiece and check for
abnormalities such as abnormal rotation,
vibration, noise, and overheating.
CAUTION
• Before turning the head cap, make sure the wrench is
correctly aligned with the cap. Do not turn the wrench at
an angle as abrasion of the wrench may occur.
• Secure the shank firmly to the handpiece head so that there
is no gap between them. A loose connection could make the
head unstable, resulting in an accident during use.
• Use only a genuine NSK cartridge. If a non genuine
cartridge is used NSK cannot guarantee performance
and the handpiece warranty would become invalid.
• Always first finger tighten the head cap then secure
firmly with the wrench.
• NSK never recommends the disassembly and repair of
any NSK cartridge. There is NO EXCEPTION. In such a
case a handpiece may perform abnormally (abnormal
noise or abnormal vibration). Damage, failure or
accidents are outside of our guarantee.
