- Check for proper air and water spray function. The handpiece features 6 sprays (3 air, 3 water) for optimal cooling and debris removal.
- Confirm the LED light is functioning. The handpiece has a built-in electric generator that powers the LED using air pressure.
Operation
- Activate the dental unit's foot pedal to initiate air flow to the handpiece.
- The handpiece will begin to rotate, and the LED light will illuminate.
- Adjust air pressure and water flow as needed via the dental unit controls.
- Apply gentle, controlled pressure during dental procedures.
- After use, release the foot pedal to stop rotation and turn off the LED.
5. Maintenance and Sterilization
Cleaning
- Immediately after each use, remove the bur.
- Wipe the exterior of the handpiece with a soft cloth dampened with a suitable disinfectant solution.
- Clean the spray nozzles with a cleaning wire if necessary to prevent clogging.
Lubrication
- Lubricate the handpiece regularly according to the manufacturer's recommendations for dental handpiece oils.
- Apply lubricant to the air drive tube and the bur chuck.
- Run the handpiece briefly after lubrication to distribute the oil.
Sterilization
The handpiece is designed for steam sterilization (autoclaving). Follow these steps:
- Clean and lubricate the handpiece as described above.
- Place the handpiece in a sterilization pouch.
- Autoclave according to the sterilizer manufacturer's instructions (typically 135°C / 275°F for 20 minutes).
- Allow the handpiece to cool completely before handling or storage.
Cartridge/Rotor Replacement
The handpiece cartridge/rotor is a precision component balanced by a German balancing machine. If replacement is necessary due to wear or damage, use only genuine replacement parts.
