NSK handpieces are manufactured using superior micro-precision production technology to tolerances of less than 1,000th of a millimetre. With over 100 years of experience, NSK is today regarded as the world’s largest dedicated manufacturer of quality precision high and low speed dental handpieces, micromotors and ultrasonic scalers.

To maintain these precision instruments in peak operating condition with the efficiency and accuracy required to perform precise clinical procedures, it is recommended that all NSK products be maintained using the following care and maintenance instructions.

1. PREPARATION

• Contra-Angle: Remove the contra-angle from the motor and detach the bur from the chuck.
• Air Turbine: Remove the air turbine from the coupling and detach the bur from the chuck.

Bring instruments to a dedicated decontamination area. Remove organic contaminants with a paper wipe.

2. MANUAL CLEANING

Clean the external surface of handpiece with running water (<38°C, demineralised water recommended).

3. LUBRICATION

• Essential after thermo-disinfection
• Essential prior to sterilisation process

Manual: Lubricate handpiece using NSK Pana Spray Plus / Pana Spray. To prevent mist spray from escaping into the environment, use absorbent cloth. Expel excess lubrication.

Automated: Clean and lubricate handpieces with NSK iCare. Be sure to use the right adaptor for each handpiece.

4. STERILISATION & STORAGE

Place handpieces in a sterilisation pouch and seal them. EN13060 4.6.3 recommends autoclaving for 20 minutes (minimum holding time) at 121°C or 15 minutes (minimum holding time) at 132°C. NSK recommends Class B or S sterilisation. (All NSK handpieces are autoclavable up to 135°C)  

After the sterilisation cycle, immediately remove handpieces from the autoclave. Keep them in dust-free, sterilised storage or bring them to a treatment room for use.

5. AUTOMATED CLEANING, DISINFECTION & STERILISATION

NSK handpieces with the unique symbol are thermo-disinfector-ready and therefore may be washed and disinfected using a thermo-disinfector. When using a thermo-disinfector, be sure to follow its manufacturer’s instructions.
