2. Allow the machine to work with water for 10 seconds before each clinical opera-
tion to remove any water remaining in the pipe.
3. Operators should be equipped with adequate protection (e.g., goggles, masks,
etc.) to prevent cross-contamination.
4. Product use must comply with the relevant operation specications and relevant
regulations of the medical department. And the operation is limited to trained doctors or
technicians.
5. Before each operation, please disinfect the accessories such as ultrasonic handpie-
ce, tip, torque wrench, air polishing handpiece and nozzle.
6. Please do not load or unload the tip while stepping on the foot pedal or the han-
dpiece is vibrating.
7. Do not step on the foot pedal button while the tail cord of the air polishing han-
dpiece has been removed from the main unit.
8. Before using the ultrasonic handpiece, make sure that the tail cord of the air po-
lishing handpiece is correctly placed on the handpiece bracket; similarly, before using
the air polishing handpiece, make sure that the ultrasonic handpiece tail plug is cor-
rectly placed on the ultrasonic handpiece bracket.
9. The tip must be tightened.
10. When the tip is damaged or worn, the vibration intensity will decrease. The ope-
rator should replace it with a new one in time according to the clinical situation.
11. Do not bend or grind the tip.
12. If the equipment is used in the anhydrous mode for a while, the temperature of
the tip may be more than 51 °C. It is recommended that the tip continuously works for
2 seconds and pause for at least 15 seconds in the anhydrous mode.
13. Under no circumstances should the air polishing handpiece nozzle be aimed at
people.
14. If the powder accidentally sprays into the eyes, it may damage eyes. We strongly
recommend that all personnel (doctors, nurses, patients) wear goggles during air po-
lishing treatment.
15. During the air polishing process, if you need to add powder to the powder tank,
please click the “Cleaning” key on the screen, wait for the internal pressure of the pow-
der tank to be released, then remove the powder tank from the machine and load the
appropriate amount of powder.
16. Before replacing the air polishing handpiece or the nozzle, please use a syringe
to blow the moisture at the joints at both ends (especially the gas interface) to prevent
moisture from entering the gas path and avoid clogging of the powder in the pipeline.
17. Do not use unclean water.
18. If a pressureless water source is used, the water surface of the pressureless water
source should be more than one meter above the patient’s head.
19. Do not pull the tail cord hard during the use of the device to avoid damage to the
tail cord.
