Contra Angle Handpiece
CAUTION
After removing, do not hold the shank upside down as it could cause the internal parts to drop.
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 OSSTEM cannot guarantee performance and the handpiece warranty
would become invalid.
Always first finger tighten the head cap then secure firmly with the wrench.
OSSTEN 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.
