CAUTION
Ř
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.
Ř
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.
Ř
Use only a genuine NSK cartridge. If a non genuine cartridge is used NSK cannot guarantee
performance and the handpiece warranty would become invalid.
Ř
Always first finger tighten the head cap then secure firmly with the wrench.
Ř
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.
Hold tight!
